This project demonstrates how to use an IR infrared sensor module with an Arduino Uno to detect the presence of objects. The IR sensor emits infrared radiation and detects reflected radiation from ...

The Arduino Uno Infrared Sensor Receiver Module detects infrared (IR) signals emitted by IR transmitters. It typically includes an IR receiver and a circuit to demodulate the received signals, ...

Have you ever wondered how speed guns measure the speed of moving vehicles or how an athlete's sprint speed is recorded? Normally these speed sensors work with radar or laser technology to bounce back ...
