Penyandang tunanetra umumnya dalam beraktivitas sehari-hari mengalami banyak kesulitan sehingga memerlukan alat bantu untuk memudahkannya. Pada penelitian ini telah dibuat desain alat bantu berbentuk kacamata. Alat ini berupa desain sistem pendeteksi penghalang menggunakan sensor ultrasonik dan sensor inframerah dengan keluaran suara untuk penyandang tunanetra. Sistem perangkat alat bantu didesain dengan bentuk kacamata berbahan akrilik. Sistem perangkat keras ini terdiri dari modul arduino, dua buah sensor ultrasonik HC-SR04, sensor inframerah, Mp3 Player, dan headset. Sensor ultrasonik 1 digunakan untuk mendeteksi jarak penghalang didepan. Sensor ini mampu mendeteksi penghalang pada jarak (0-45) cm, (45-120) cm, atau (120-250) cm dengan Mp3 Player mengeluarkan suara 1, suara 2, atau suara 3. Jika sensor ultrasonik 1 mendeteksi adanya penghalang, maka sensor Inframerah akan aktif dan ikut mendeteksi penghalang tersebut. Sensor Inframerah yang mendeteksi radiasi inframerah manusia di depan sensor mengakibatkan Mp3 Player mengeluarkan suara 4. Jarak maksimum deteksi sensor inframerah sampai 700 cm dengan kondisi manusia bergerak dan 30 cm untuk manusia yang diam. Sensor ultrasonik 2 diatur untuk mendeteksi jarak kemiringan sebesar 60o terhadap permukaan lintasan, dimana sensor tersebut memiliki batas jarak kemiringan 73 cm sampai 89 cm yang sudah terprogram pada arduino. Jika sensor ultrasonik 2 mendeteksi adanya jarak kemiringan yang kurang dari 73 cm, maka Mp3 Player mengeluarkan suara 5, sedangkan jika jarak kemiringan sensor melebihi dari 89 cm, maka Mp3 Player mengeluarkan suara 6. Blind people generally experience many difficulties in their daily activities so they need tools to make it easier. In this research, a glasses-shaped tool has been designed. This tool is a barrier detection system design using ultrasonic sensors and infrared sensors with sound output for blind people. The system of assistive devices is designed in the form of glasses made from acrylic. This hardware system consists of the Arduino module, two HC-SR04 ultrasonic sensors, an infrared sensor, an Mp3 Player, and a headset. Ultrasonic sensor 1 is used to detect the distance of the barrier in front. This sensor can detect obstructions at a distance of (0-45) cm, (45-120) cm, or (120-250) cm with the Mp3 Player emitting 1 sound, 2 sound, or 3 sound. If the ultrasonic sensor 1 detects a barrier, then the infrared sensor will be active and will detect the barrier. An infrared sensor that detects human infrared radiation in front of the sensor causes the Mp3 Player to make a sound. 4. The maximum detection distance of the infrared sensor is up to 700 cm with human conditions moving and 30 cm for humans who are still. The ultrasonic sensor 2 is set to detect a slope distance of 60o against the track surface, where the sensor has a slope distance of 73 cm to 89 cm which has been programmed on Arduino. If the ultrasonic sensor 2 detects a tilt distance of less than 73 cm, the Mp3 Player makes a sound of 5, whereas if the sensor's tilt distance exceeds 89 cm, the Mp3 Player makes a sound of 6.

Robot sensing requires two types of observation – intensive and wide-angle. We selected multiple ultrasonic sensors for intensive observation and an image sensor for wide-angle observation in measuring a moving object’s motion with sensors in two kinds of fusion – one fusing multiple ultrasonic sensor data and the other fusing the two types of sensor data. The fusion of multiple ultrasonic sensor data takes advantage of object movement from a measurement range of an ultrasonic sensor to another sensor’s range. They are formulated in a Kalman filter framework. Simulation and experiments demonstrate the effectiveness and applicability to an actual robot system.

Penelitian ini bertujuan untuk menentukan nilai frekuensi osilasi pada dua pendulum terkopel menggunakan Arduino Uno dengan sensor ultrasonik. Gerak osilasi pendulum yang berbeda yaitu pada gerak sefase dan beda fase. Sensor ultrasonik dihubungkan pada board Arduino Uno yang kemudian dihubungkan pada PC menggunakan kabel USB. Proses pengambilan data dimulai dengan menggerakkan pendulum secara sefase dan menekan tombol conect pada aplikasi PLX-DAQ untuk memperoleh data yang secara otomatis akan ditampilkan pada microsoft excel. Selanjutnya, data yang diperoleh dilakukan analisis fitting data, kemudian hasilnya di-plot dalam bentuk grafik. Hasil menunjukkan perbedaan nilai frekuensi osilasi pada perbandingan pengukuran menggunakan tracker dan sensor ultrasonik. secara eksperimen menggunakan tracker, nilai ω sebesar 4,62 Hz dan secara teori nilai ω sebesar 5,66 Hz dengan ralat 18,4 %. Sedangkan pada sensor ultrasonik diperoleh nilai ω secara eksperimen sebesar 4,95 Hz dan secara teori sebesar 5,66 Hz dengan ralat 12,55%. Perbandingan pengukuran tersebut dapat dilihat bahwa nilai ω secara eksperimen menggunakan sensor ultrasonik lebih besar atau mendekati pada nilai ω secara teori. Artinya pengukuran frekuensi osilasi dengan menggunakan sensor ultrasonik juga memiliki tingkat akurasi yang baik sehingga layak digunakan dalam eksperimen osilasi terkopel. This study aims to determine the value of the oscillation frequency in two coupled pendulums using Arduino Uno with an ultrasonic sensor. The different pendulum oscillations are in phase and phase difference. The ultrasonic sensor is connected to the Arduino Uno board which is then connected to the PC using a USB cable. The data collection process begins by moving the pendulum in phases and pressing the connect button on the PLX-DAQ application to obtain data which will automatically be displayed on Microsoft Excel. Furthermore, the data obtained were analyzed using a fitting data analysis, then the results were plotted in graphical form. The results show the difference in the value of the oscillation frequency in the comparison of measurements using a tracker and ultrasonic sensor. experimentally using a tracker, the value of ω is 4.62 Hz and in theory, the value of ω is 5.66 Hz with an error of 18.4%. While the ultrasonic sensor obtained an experimental ω value of 4.95 Hz and theoretically 5.66 Hz with 12.55% error. Comparison of these measurements can be seen that the value of ω experimentally using an ultrasonic sensor is greater or closer to the value of ω in theory. This means that the measurement of oscillation frequency using an ultrasonic sensor also has a good level of accuracy so it is suitable to be used in coupled oscillation experiments.

Full textAbstract:
Photoacoustic imaging is a new type of noninvasive, nonradiation imaging modality that combines the deep penetration of ultrasonic imaging and high specificity of optical imaging. Photoacoustic imaging systems employing conventional ultrasonic sensors impose certain constraints such as obstructions in the optical path, bulky sensor size, complex system configurations, difficult optical and acoustic alignment, and degradation of signal-to-noise ratio. To overcome these drawbacks, an ultrasonic sensor in the optically transparent form has been introduced, as it enables direct delivery of excitation light through the sensors. In recent years, various types of optically transparent ultrasonic sensors have been developed for photoacoustic imaging applications, including optics-based ultrasonic sensors, piezoelectric-based ultrasonic sensors, and microelectromechanical system-based capacitive micromachined ultrasonic transducers. In this paper, the authors review representative transparent sensors for photoacoustic imaging applications. In addition, the potential challenges and future directions of the development of transparent sensors are discussed.

Full textAbstract:
Human motion analysis is a valuable tool for assessing disease progression in persons with conditions such as multiple sclerosis or Parkinson’s disease. Human motion tracking is also used extensively for sporting technique and performance analysis as well as for work life ergonomics evaluations. Wearable inertial sensors (e.g., accelerometers, gyroscopes and/or magnetometers) are frequently employed because they are easy to mount and can be used in real life, out-of-the-lab-settings, as opposed to video-based lab setups. These distributed sensors cannot, however, measure relative distances between sensors, and are also cumbersome when it comes to calibration and drift compensation. In this study, we tested an ultrasonic time-of-flight sensor for measuring relative limb-to-limb distance, and we developed a combined inertial sensor and ultrasonic time-of-flight wearable measurement system. The aim was to investigate if ultrasonic time-of-flight sensors can supplement inertial sensor-based motion tracking by providing relative distances between inertial sensor modules. We found that the ultrasonic time-of-flight measurements reflected expected walking motion patterns. The stride length estimates derived from ultrasonic time-of-flight measurements corresponded well with estimates from validated inertial sensors, indicating that the inclusion of ultrasonic time-of-flight measurements could be a feasible approach for improving inertial sensor-only systems. Our prototype was able to measure both inertial and time-of-flight measurements simultaneously and continuously, but more work is necessary to merge the complementary approaches to provide more accurate and more detailed human motion tracking.

This work proposes a new positioning method based on multiple ultrasonic sensors for the autonomous mobile robot. Unlike the conventional ultrasonic positioning methods, this new method can realize higher accuracy ultrasonic positioning without additional temperature information. Three ultrasonic sensors are used for positioning. A generalized measurement model is established for general sensor configuration. A simplified measurement model, which considers the computational complexity, is also established for linear/simplified sensor configuration. Three time-of-flight signals are obtained from the three ultrasonic sensors. The coordinates of the target are calculated by the ratios of time-of-flights. Positioning experiments were carried out to verify the feasibility and effectiveness of the proposed method. Experimental results show that the new ultrasonic positioning method is effective, both the two established models can implement positioning successfully, and the positioning accuracy is satisfactory. Compared with the conventional ultrasonic positioning method with the default ultrasonic velocity, the positioning accuracy is greatly improved by the proposed method. Compared with the ultrasonic positioning method with additional temperature compensation, the results obtained by the proposed method are comparable.

Abstract: Most of the braking systems used still use the drum system so that an automatic braking system is needed so that collisions rarely occur due to sudden braking which results in many accidents that claimed lives. This automatic brake control system is a device that functions as an automatic braking controller on four-wheeled vehicles without the driver having to press the brake pedal or brake manually. This system uses ultrasonic sensors to detect the distance of the car to objects that are in the way both in front and behind the car. Controlled by Arduino Uno microcontroller which is connected to servo motor and buzzer. The system can control the speed of vehicles and parking cars in the parking lot by designing and making a braking and parking system that works using ultrasonic sensors so that it can notify objects or things that are blocking both in front and behind the car. The car can stop quickly and accurately so it doesn't touch the object in front of it and the car can also park properly in the designated parking space.

This paper described fabrication and comparison of embedded ultrasonic sensors for NDE applications. A 1-3 cement-based piezoelectric composite was used as the sensing element of the ultrasonic sensor. As a front matching layer between test material and piezoelectric materials, cement/epoxy resin was selected. In order to make the backing materials for sensors had enough acoustic attenuation performance, the backing material of sensors doped with tungsten powder. When the mass ratio of tungsten/cement backing was two and the thickness of cement/epoxy resin front-face matching was 3mm, the 1-3 cement-based piezoelectric ultrasonic sensor showed a significant enhancement in both relative pulse-echo sensitivity and-6dB bandwidth. These promising results suggested the great potential for developing high-performance ultrasonic sensors using the 1-3 cement-based piezoelectric composite.

A sapphire ultrasonic temperature sensor was produced in this study which possessed working stability, antioxidation properties, and small acoustic-signal attenuation. A method was developed to solve the problems of long periods (>0.5 h) and ultrahigh temperature (1800°C) in tests. The sensor adopted here had good sound transmission performance as well as the high thermal conductivity of sapphire single crystals (Al2O3), as ultrasonic waveguides. The ultrasonic waveguide was produced by the method of the laser-heated pedestal growth (LHPG method). Calibration experiments in a high temperature furnace found that, at high temperatures and long exposure, sapphire ultrasonic temperature sensors had good stability and repeatability, and it survived in 1600°C for 360 min. This sapphire ultrasonic temperature sensor has potential for applications in aircraft engines where monitoring of high temperatures is very important.

Flooding is a natural disaster that is troubling for the community. Floods occur due to overflowing water from rivers, lakes, or gutters. The flood also caused material losses and even caused casualties. Sampang Regency is one of the districts located on Madura Island which is often flooded.The Raspberry Pi is a mini computer that is capable of performing the same tasks as a computer. The use of the Raspberry Pi as a server is more efficient than using a PC server which in terms of price is very expensive. The Raspberry Pi can also be combined with various sensors because it has 40 pins as a connector. The Parallax Ping sensor is an ultrasonic sensor that can detect the distance of an object by emitting ultrasonic waves with a frequency of 40 KHz and then detecting the reflection. By using an ultrasonic sensor as a water level counter, the height value of the river will be obtained. From this height value, it is then processed using the fuzzy mamdani method to produce a river water level status. This elevation status will then be informed to the public.Based on the test results, this flood detection system uses an ultrasonic sensor as a water level meter that is controlled by the Raspberry Pi. Data from ultrasonic sensors then calculated by fuzzy mamdani method can produce water level status. The water level status is obtained from the height data of the water surface calculated by using an ultrasonic sensor. The water level status is then sent to a cellphone number using a wavecom modem.

To reduce the risk of elderly people falling in a private room without relying on a closed-circuit television system that results in serious privacy and trust concerns, a fall monitoring system that protects the privacy and does not monitor a person’s activities is needed. An ultrasonic-based sensor system for elderly fall monitoring in a smart room is proposed in this study. An array of ultrasonic sensors, whose ranges are designed to cover the room space, are initially installed on a wall of the room, and the sensors are rotated to transmit and receive ultrasonic signals to measure the distances to a moving object while preventing ultrasonic signal interference. Distance changes measured by ultrasonic sensors are used as time-independent patterns to recognize when an elderly person falls. To evaluate the performance of the proposed system, a sensor system prototype using long short-term memory was constructed, and experiments with 25 participants were performed. An accuracy of approximately 98% was achieved in this experiment using the proposed method, which was a slight improvement over that of the conventional method.

A fatigue crack and its precursor often serves as a source of nonlinear mechanism for ultrasonic waves, and nonlinear ultrasonic techniques have been widely studied to detect fatigue crack at its very early stage. In this study, a wireless sensor node based on nonlinear ultrasonics is developed specifically for fatigue crack detection: (1) through packaged piezoelectric transducers, ultrasonic waves at two distinctive frequencies are generated, and their modulation due to a microcrack (less than 0.1 mm in width) is detected; (2) an autonomous reference-free crack detection algorithm is developed and embedded into the sensor node, so that users can simply “stick” the sensor to a target structure and automatically “detect” a fatigue crack without relying on any history data of the target structure; and (3) the whole design of the sensor node is fulfilled in a low-power working strategy. The performance of the sensor node is experimentally validated using aluminum plates with real fatigue cracks and compared with that of a conventional wired system. Furthermore, a field test in Yeongjong Grand Bridge in South Korea has been conducted with the developed sensor nodes.

In this paper, method of designing an Ultrasonic Tomography System due to the propagation manner of ultrasonic wave inside the various materials is investigated. The correct method of mounting of Ultrasonic sensors and behavior of the ultrasonic wave propagation in different layers has been simulated by the use of finite element software (COMSOL Multiphysics 3.5). To increase in practical nondestructive evaluation and inspection, we should increase our understanding of the basic physics and wave mechanics associated with guided wave inspection. A suitable ultrasonic sensor base on its efficiency and satisfying the simulation criteria is found and practically implemented on the surface of metal pipe. it is done by estimating the resonance frequency of sensor due to manner of ultrasonic wave propagation in different frequencies shown in simulation results.

Due to its payload, size and computational limits, localizing a micro air vehicle (MAV) using only its onboard sensors in an indoor environment is a challenging problem in practice. This paper introduces an indoor localization approach that relies on only the inertial measurement unit (IMU) and four ultrasonic sensors. Specifically, a novel multi-ray ultrasonic sensor model is proposed to provide a rapid and accurate approximation of the complex beam pattern of the ultrasonic sensors. A fast algorithm for calculating the Jacobian matrix of the measurement function is presented, and then an extended Kalman filter (EKF) is used to fuse the information from the ultrasonic sensors and the IMU. A test based on a MaxSonar MB1222 sensor demonstrates the accuracy of the model, and a simulation and experiment based on the T h a l e s I I MAV platform are conducted. The results indicate good localization performance and robustness against measurement noises.

The project we designed is used to develop a distance measurement system using ultrasonic waves and interfaced with Arduino UNO. We know that the human audible range is from 20hz to 20khz. We can use these frequency range waves through ultrasonic sensor HC-SR04. The main advantages of this sensor are when this sensor is interfaced with Arduino which is a control system and a sensing system, a proper calculation of the distance measurement can be done by using different types of new techniques. As huge amounts are spent on hundreds of inflexible circuit boards, the Arduino board will allow the business to bring many more unique devices. These distance measurement systems are mostly used as range meters and as proximity detectors in the different types of industries. The hardware part of the ultrasonic sensor is interfaced with the Arduino Uno board. This type of measuring distance is an efficient way to measure even small distances accurately. The distance of an object from the sensor is measured by using an ultrasonic sensor. After knowing the speed of the sound wave the distance of an object can be calculated.
