Fire Alarm System using Arduino and GSM 🚨🔥 This project is a smart fire alarm system using an Arduino Uno, GSM module, and sensors to detect fire and smoke. The system triggers an alarm, displays ...

The circuit is highly-flexible so that you can use any SIM900A modem (and ofcourse any Arduino Uno board) of your choice. Carefully read the modem documentation before construction to make the task ...

This paper presents a novel solution to these challenges through the implementation of a prepaid energy meter system utilizing a GSM Module and Arduino Uno. The proposed system not only facilitates ...

With the use of Arduino, the system is easy to operate and can be customized to meet specific patient needs. The combination of the accelerometer, GSM, and GPS modules provides a reliable and ...

Shown below is the basic hardware setup diagram. Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C control, and the module is 3.3 V powered by the Arduino itself. It seems ...

Arduino have launched an upgrade to their 8-bit Arduino UNO R3 board with the Arduino UNO R4 featuring a 48 MHz Renesas RA4M1 Arm Cortex-M4F 32-bit microcontroller, and an optional ESP32-S3 module for ...

With no plans to discontinue the popular UNO R3, the UNO R4 will come in two versions – UNO R4 WiFi and UNO R4 Minima. The UNO R4 is powered by the Renesas RA4M1 32-bit microcontroller based on the ...
