This project involves using an Arduino to measure distances using an ultrasonic sensor and controlling a buzzer and LED based on the measured distance. The provided Arduino code performs the following ...

Works with the HC-SR04 ultrasonic sensor in the 3 Pin Mode/4 Pin Mode, the Ping))) ultrasonic sensor in the 3 Pin Mode and the DHT temperature/humidity sensors for getting precise distance values. !

How the Kisan Mitra Chhadi works, from its 5 to 15-metre detection range to the vibration alert that could help farmers avoid ...

Abstract: Fringe field-based capacitive proximity sensors are well-suited to detect the presence of both conducting and nonconducting objects. The configuration of electrodes within these sensors ...
