Abstract:
<p><em><span>Temperature is an object of research that is often studied. Research on temperature is within the scope of control and monitoring. The process of controlling and monitoring temperature is influenced by the selection of the right temperature sensor. The temperature sensors that are often used are the LM35 sensor and the DHT11 sensor. The LM35 sensor has advantages in terms of a simple design and easy to implement, while the DHT11 sensor has the advantage because in one sensor package there are two functions, namely to measure air temperature and humidity. In this study, temperature measurement accuracy was carried out to facilitate researchers in determining the right temperature sensor. The data monitoring method uses the internet of things (IoT). The results of the research show that the DHT11 temperature sensor is more accurate and more stable than the LM35 temperature sensor. The results of the sensor test at room temperature, the DHT11 sensor has an accuracy rate of 97.21% while the LM35 sensor has an accuracy rate of 96.86%. While the results of the sensor test in the server room, the DHT11 sensor has an accuracy rate of 95.26%, while the LM35 sensor has an accuracy rate of 90.32%.</span></em></p>

Abstract:
Noise merupakan parameter yang selalu muncul dalam setiap proses akuisisi data dari sebuah sensor. Sensor yang digunakan adalah jenis DHT11 dan LM35 yang dipasangkan pada arduino mega untuk memantau suhu ruangan laboratorium sesuai ketentuan ISO 17025. Kalman Filter dapat menghilangkan atau mengurangi noise dari sensor. Keberhasilan Kalman Filter dalam menghilangkan noise ditentukan oleh nilai R yang disebut kovarian noise pengukuran dan Q yang disebut kovarian noise proses. Nilai R dan Q dapat meningkatkan performa Kalman Filter dalam menghilangkan noise. Kalman Filter diaplikasikan pada sensor suhu jenis LM35 dengan keluaran berupa tegangan dan sensor suhu jenis DHT11 dengan keluaran derajat celcius. Selisih penunjukkan data sensor sebelum dan sesudah menggunakan Kalman Filter dengan nilai selisih variansi hasil filter lebih kecil dibandingkan dengan variansi tanpa filter, pada suhu konstan selisih variansi sama dengan nol untuk DHT11 dan 0,14 untuk LM35. Sedangkan pada suhu tidak konstan didapat selisih variansi 0,8 untuk DHT11 dan 0,3 untuk LM35.

Abstract:
Conventional fire protection systems, characterized by low installation costs, often lack the sophistication to provide optimal protection, especially in high-rise buildings. This study aims to refine the operational productivity concerning fire prevention and evacuation by embracing a detailed fire safety framework that leverages Internet of Things (IoT) capabilities. This prototype integrates SMS and phone call alerts to facilitate timely response in case of fire detection. The system utilizes three key sensors: a KY-026 flame sensor module, an MQ-2 gas and gas sensor, and an LM35 temperature sensor. Testing results indicate significant sensor value variations between normal and fire conditions. The KY-026 flame sensor module, for instance, exhibited an average reading of 137.3 under normal conditions and 895.2 during fire detection. Similarly, the MQ-2 sensor recorded 1234.7 ppm and 4237.8 ppm, respectively. The LM35 temperature sensor measured 28.34°C and 48.46°C under normal and high-temperature conditions. Despite the sensors showcasing commendable efficacy, they displayed a minor error margin fluctuating between 0.04% and 1.08%.

Abstract:
Catfish is one of the fishery products favored by the community because of its high protein. So that Catfish is one of the fish that is the center of business for fish farmers. The pond conditions used by Catfish farmers are generally still conventional. So that the maintenance of clean water in ponds is still done manually and even escapes attention. Water conditions will affect the health and productivity of Catfish. In order to achieve the optimum conditions in the third media, a control system consisting of three types of sensors will be used, namely Flowmeter, LDR sensor and LM35 sensor. The flowmeter sensor is used to regulate the flow of water, the LDR sensor functions as a receiver that is used to detect the level of turbidity of water based on how much light enters the water (turbidity). Meanwhile, the LM35 sensor functions to detect the temperature in the media so that the optimum condition for Catfish based on temperature parameters is around 22 - 32 ° C

Abstract:
Premature babies who are born alive before 37th week of gestation or babies born with weight criteria of less than 2500 grams need to be treated in an infant incubator because they are very susceptible to viruses in open spaces and will provide protection to newborns by providing premature babies stable temperature and humidity. Stable temperature regulation is needed to prevent hypothermia or hyperthermia that will occur in premature babies. Care of the baby in an infant incubator causes the separation of mother and baby. Mothers who have premature babies are found to lack trust in caring for their babies compared to mothers who have term babies. The purpose of this study was to analysis of temperature on baby incubator control system. In order to get a stable and precise temperature, the temperature sensor is positioned according to the standard of the baby incubator at the hospital. This research uses LM35 and DS18B20 temperature sensors which will be processed using Atmega 328 Microcontroller and will be displayed on a PC (personal computer). Based on the measurement results obtained an average value of min difference for sensor readings on the LM35 has the largest value of 0.22°C and the average max value difference has the largest value of 0.38°C and the average value of the min difference for the sensor readings on the LM35 has a value the largest is 0.39°C and the average difference in the value of max has the largest value that is 0.55°C. It can be concluded that the LM35 sensor is better than the DS18B20 sensor because it has smaller oscillations and also good accuracy. The results of this study can be implemented in infant incubators in accordance with established standards and can be produced at affordable prices in the domestic market.

Abstract:
The design and implementation of a Peltier-based mobile solar vaccine refrigerator is presented in this report. The refrigerator is specifically developed to provide reliable and portable storage of vaccines in areas with limited access to electricity. The system utilizes Peltier sensors, powered by a combination of a lithium-ion battery and a solar panel, to achieve the required cooling effect. The Peltier sensors provide cooling by utilizing the thermoelectric effect, while the liquid cooling system and air cooling system helps to dissipate heat efficiently. The solar panel and lithium-ion battery enable autonomous operation and recharge the battery during daylight hours. An LM35 temperature sensor is employed to monitor the internal temperature of the refrigerator, and the temperature readings are displayed on a 16x2 LCD display connected to an Arduino. This mobile solar vaccine refrigerator represents an innovative and sustainable solution for vaccine storage, overcoming the challenges posed by unreliable electricity supply in remote areas. The combination of Peltier technology and solar power offers a cost-effective and environmentally friendly approach to maintaining vaccine integrity and efficacy. The successful implementation of this design holds great potential for enhancing healthcare services and facilitating vaccination campaigns in underserved regions worldwide.

Abstract:
Research into health-related demands is a permanent fixture among the many IoT requests. The rising popularity of Internet of Things (IoT) approaches in the healthcare sector can be attributed to their potential to reduce expenses, improve clarity of communication, and restore patients' sense of satisfaction with their care. This study provides inspiration for visualising the potential of IoT in intricate medical operations. One of the most important Internet of Things (IoT) apps that connects mobile sensors, people, clinicians, networks, and other linked devices is the "Mobile Healthcare Management System (HMS)". The overarching goal of this work is to design a simple and inexpensive health monitoring system for people living in areas where access to specialised medical care is limited. This setup is easily transportable. Cost-effective and simple enough that even those with no special training can use it successfully. Moreover, Internet of Things (IoT) technology is used in the development of this idea so that information can be transmitted to a distant server and retrieved by physicians. This project makes use of a NODE MCU, an LM35 temperature sensor, a pulse sensor, and a 16x2 LCD display. Create an account with one of the IoT platforms that supports ThingTalk. The Username, Device-Id, Asset-Id, Secret key, etc., for the IoT account must be written down and entered into the Arduino code. All of these credentials, together with individual pin numbers for assets (Parameters), are added to the Arduino application. The NODE MCU has an internal ESP8266 Wi-Fi interface, so it may send the parameters read in the preceding operation to the IoT account together with the corresponding pin numbers

Abstract:
This research work was carried out for the purpose of modeling and simulation of temperature control in the anaerobic fermentation of waste water in a bioreactor or controlled fermentation reactor. Research carried out at the Professional School of Agroindustrial Engineering of the National University of Moquegua, Peru.It consists of using the LabVIEW software from National Instrument that allows graphic programming without the need for a programming specialist. Temperature control is applied in the on/off mode, which has control of the minimum and maximum temperature based on a Set point, where if the Set point value is modified, the minimum and maximum temperature is automatically modified. . For this, an analog temperature sensor is used, which is Lm35, which in this case is simulated and is an input variable and the output variable is the system cooler. In the block panel, a While Loop cycle is created for the installed indicators, the voltage to temperature converters are created. A SubVI is opened for the Lm35 to temperature converter. Using all this instrumentation, it was possible to carry out the modeling, simulation and temperature control in the bioreactor for the anaerobic fermentation of waste water, obtaining the results expected by this research using the LabVIEW software.

Abstract:
Most of the activities in the modern world are heavy power consumers. Therefore, wasting of power is identified as a critical factor which is badly impacted the environmental and economic growth. Using electrical appliances such as ceiling fans and bulbs in the commercial and domestic environment unnecessarily is identified as a main way of wasting power. As a solution, this paper proposes the designing and producing of a power saving device for ceiling fans and bulbs. Variables such as room temperature, light intensity and the number of people present in the location were considered as parameters to control ceiling fans and bulb automatically, so as to save power by changing the speed and turning off when not necessary. This device is consisting of six main units namely a main control unit using Arduino Nano microcontroller, bidirectional visitor counter unit using two Passive Infrared motion sensors, temperature and light intensity measuring unit using a LM35 temperature sensor and a light dependent resistor sensor, an output display unit using 1604 LCD display, ceiling fan controller unit using a fan regulator that was constructed using two RC circuits, a relay module and a bulb controller unit. Ceiling fan speed and the delay time to switch off the appliances is controlled using a fuzzy logic controller. Inputs of the fuzzy logic controller are temperature difference with the set temperature, rate of change of temperature difference within a five-minute interval, difference of the number of people inside the location with the set number of people and the rate of change of number of people within a five-minute interval. It was observed that, for the test cases, an average of 318Wh per day could be saved from a single bulb and a ceiling fan while avoiding unnecessary usage of appliances. KEYWORDS: Energy saving, fuzzy logic controller, Passive Infrared motion sensor, bidirectional visitor counter, fan regulator, room temperature and light intensity.
