Pengukuran jarak yang akurat merupakan komponen kunci dalam berbagai aplikasi teknologi termasuk robotika, sistem keselamatan, dan kontrol industri. Penelitian ini bertujuan untuk mengevaluasi keakuratan pengukuran jarak benda menggunakan sensor ultrasonik HC-SR04 yang dikendalikan oleh mikrokontroler NodeMCU ESP8266. NodeMCU ESP8266 dipilih karena integrasi Wi-Fi yang memungkinkan data dikirim secara nirkabel ke server untuk analisis lebih lanjut. Metode penelitian ini meliputi pengujian sensor ultrasonik pada berbagai jarak dan kondisi lingkungan untuk mengetahui keakuratan dan konsistensi hasil pengukuran. Hasil pengujian menunjukkan bahwa akurasi sensor ultrasonik menurun seiring dengan bertambahnya jarak pengukuran. Selain itu, kondisi lingkungan seperti suhu, kelembaban, dan permukaan benda juga mempengaruhi keakuratan pengukuran. Oleh karena itu, diperlukan kalibrasi tambahan untuk memastikan ketepatan pengukuran dalam kondisi lingkungan yang bervariasi. Penelitian ini menyimpulkan bahwa sensor ultrasonik berbasis NodeMCU 8266 dapat digunakan sebagai solusi yang efektif untuk aplikasi pengukuran jarak, namun kalibrasi dan penyesuaian diperlukan untuk menjamin keakuratan data pada berbagai kondisi. Hasil ini memberikan kontribusi penting terhadap pengembangan sistem otomasi yang lebih cerdas dan responsif.

In this research paper, we proposed an Internet of Things (IoT) based ATM security system using the NodeMCU ESP8266 module, PIR (Passive Infrared) sensor, LCD display with I2C interface, and the Telegram app. The proposed system utilizes the NodeMCU ESP8266 module, which is a low-cost Wi-Fi enabled microcontroller, as the main controller for the security system. The PIR sensor is used to detect motion or presence near the ATM, which can potentially indicate unauthorized access. The LCD display with I2C interface is used to provide real-time status information about the ATM, such as Motion Detected or NO Motion. When the PIR sensor detects any suspicious activity near the ATM, the NodeMCU ESP8266 module sends a notification to the ATM owner or security personnel via the Telegram app. The notification includes details about the detected activity, allowing the owner or security personnel to take immediate action. The real- time alerts enable prompt response to potential security breaches and help prevent unauthorized access to the ATM.

The process of the gas station’s fuel tank volume measurement that is used today is still mostly done manually using a measuring line or dipstick. This research develops a real-time fuel tank volume measurement system. This system sends measurement data to server if the system is connected to internet network. This system uses ultrasonic sensors to measure level of the fuel surface and uses NodeMCU ESP8266 as a controller and delivery via Wi-Fi. The ultrasonic sensor is directed into the buried tank in a position perpendicular to the surface of the liquid. The distance measurement results are obtained by calculating the transmitting time of the transmitter until it is received back by the receiver. Then, the calculation of the tank volume obtained from the distance calculation results is inserted into the equation for the area of the tank circle which is processed using the NodeMCU ESP8266 as the main controller. The volume measurement results are sent by the NodeMCU ESP8266 to webserver to be displayed on website and saved to database. The results of measuring the volume of the tank are quite accurate but there is still an average error of about 1.3. This is influenced by the slight bend in the tank.

Abstract - The system consists of an MQ2 gas sensor connected to an ESP8266 (NodeMCU) microcontroller, which detects gas leakages by sending alerts to users through the Blynk IoT platform. The ESP8266 performs Wi-Fi connection after start-up, then proceeds to read gas levels through its analog input. The sensor value is read by the system once every 2 seconds before it sends the data to the Blynk application. When gas concentration surpasses the set limit, the system creates an alert that switches off the LED light and activates the relay or motor equivalent to an exhaust fan or buzzer and sends immediate notifications to users through Blynk. When the gas measurement shows safety, the system activates the LED light while keeping the motor powered down. Remote monitoring occurs indefinitely because this configuration allows instant notification of gas leaks.

The use of the internet of things (IoT) in solar photovoltaic (PV) systems is a critical feature for remote monitoring, supervising, and performance evaluation. Furthermore, it improves the long-term viability, consistency, efficiency, and system maintenance of energy production. However, previous researchers' proposed PV monitoring systems are relatively complex and expensive. Furthermore, the existing systems do not have any backup data, which means that the acquired data could be lost if the network connection fails. This paper presents a simple and low-cost IoT-based PV parameter monitoring system, with additional backup data stored on a microSD card. A NodeMCU ESP8266 development board is chosen as the main controller because it is a system-on-chip (SOC) microcontroller with integrated Wi-Fi and low-power support, all in one chip to reduce the cost of the proposed system. The solar irradiance, ambient temperature, PV output voltage and PV output current, are measured with photo-diodes, DHT22, impedance dividers and ACS712. While, the PV output power is a product of the PV voltage and PV current. ThingSpeak, an opensource software, is used as a cloud database and data monitoring tool in the form of interactive graphics. The results showed that the system was designed to be highly accurate, reliable, simple to use, and low-cost.

<span>The use of the internet of things (IoT) in solar photovoltaic (PV) systems is a critical feature for remote monitoring, supervising, and performance evaluation. Furthermore, it improves the long-term viability, consistency, efficiency, and system maintenance of energy production. However, previous researchers' proposed PV monitoring systems are relatively complex and expensive. Furthermore, the existing systems do not have any backup data, which means that the acquired data could be lost if the network connection fails. This paper presents a simple and low-cost IoT-based PV parameter monitoring system, with additional backup data stored on a microSD card. A NodeMCU ESP8266 development board is chosen as the main controller because it is a system-on-chip (SOC) microcontroller with integrated Wi-Fi and low-power support, all in one chip to reduce the cost of the proposed system. The solar irradiance, ambient temperature, PV output voltage and PV output current, are measured with photo-diodes, DHT22, impedance dividers and ACS712. While, the PV output power is a product of the PV voltage and PV current. ThingSpeak, an open-source software, is used as a cloud database and data monitoring tool in the form of interactive graphics. The results showed that the system was designed to be highly accurate, reliable, simple to use, and low-cost.</span>

Electrical energy monitoring is increasingly important nowadays for residential and commercial usage. The energy meters are installed in consumer’s houses to track their energy usage. There are many chances of human mistakes for every electricity consumer while recording the manual energy meter reading in their houses. Also, the consumer does not have updated information about current electricity usage in each hour, day, and month. To overcome the above problems, the system is developed to remotely monitor from any world location using the NodeMCU and Arduino IDE. The energy monitoring is carried out by using the Node MCU, Arduino IDE, and PZEM-004T sensor. The PZEM-004T module is coupled to the Arduino controller. The sensor module receives a signal from the CT coil which is connected to load. The load parameters such as voltage current power etc., are measured and transferred to the Arduino. A NodeMCU ESP8266 is utilized as a Wi-Fi chip system. By using a Wi-Fi connection and the internet, the acquired data is sent to Thing Speak to save in the cloud to monitor the measured parameters remotely. The power analyzer instrument is also used to measure the real-time parameters consumed by the load which is used to cross verification and compare with the sensor measuring parameters. The passive load resistance, inductance, and 100-watt lamp loads are experimentally connected and tested. The load consumed electrical parameters such as current, voltage, power, power factor, real power, and frequency are monitored in online. Energy monitoring online may reduce the consumer's mistakes by recording the parameters and consumers can know each hour, day, and month's energy consumption up to date according to their usage.

Work as a nurse requires direct contact with patients, for example when carrying drugs or changing IVs. However, since the COVID-19 pandemic, awareness to reduce direct contact with patients is increasingly needed. Moreover, direct contact with patients with infectious diseases, such as covid-19. For this reason, it is necessary to create a tool / robot that can connect nurses and patients, especially patients with infectious diseases. In this study, a robot design and implementation was made that can assist nurses in delivering drugs to patients, without having to make direct contact with patients. IoT-based designed robots using NodeMCU, ESP8266 and Blynk. NodeMCU ESP8266 is used as a data processor and smartphones are used as remote controls via the internet. Data from the smartphone is processed by NodeMCU then sends a signal to the robot actuator via the L298N driver motor to drive the wheels. Furthermore, the internet-connected IP camera is used for live streaming on smartphones through the V380 Pro application as a directional guide. Then to prevent collisions, the ultrasonic sensor HCSR04 will send data to NodeMCU ESP8266 if there is an obstacle at a distance of 30 cm in front of the robot, so that the robot will move backwards. The experimental results show that the robot can run well where the robot is controlled by a nurse using the Blynk IoT application and V380 Pro on a smartphone via internet media. Then the test was carried out with two methods, namely smartphones using the robot's local Wi-Fi connection and smartphones using cellular networks. The results showed that the response time of the application command on the smartphone to the robot or viewing video results from the IP Camera was affected by the condition of the internet network used.
