Introduction to IR Sensors
Infrared (IR) light is invisible electromagnetic radiation. Everything absorbs and emits IR, and it's utilised in a plethora o..
IR (Infrared) sensor tuned to 38KHz, perfect for receiving commands from a TV remote control. Runs at 3V to 5V so it's great for use on the Raspberry Pi!
To use, connect pin 3 (all the way to the right) to 5V power, pin 2 (middle) to ground and listen on pin 1. It doesn't do any decoding of the signal, just passes the 'raw data' along.
