An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Like all IR sensor it has three pins which are 5V, Gnd and Out respectively. The module is powered by the 5V pin from Raspberry Pi and the out pin is connected to GPIO14 of Raspberry Pi. The ...

This project is based on an infrared (IR) sensor, which detects the presence of hands and consequently activates the motor pump to dispense alcohol-based sanitiser. The circuit is economical, reliable ...

Also, you can adjust the sensitivity of the sensor to detect the obstacles located near or far from the sensor. Figure-1, Schematic diagram of the IR obstacle detector. According to the TSOP1738 ...
