IR DETECTOR CIRCUIT


Posted on Feb 6, 2014

The circuit uses an IR phototransistor, Q1, to detect a remote control`s IR output signal. A PNP transistor, Q2, then amplifies Q1`s output and lights LED1. That indicates that an infrared signal has been detected by the phototransistor, or in other words, that your remote control works.
