The basic principle is to control the switching of the relays using a remote, which then switches on or off the load connected to them. This made some sense. Hello Select your address All Hello, Sign in. These is typical work of my project; i love every explaination here and i will like to have them more, as i extend gratitude tarun agarwal for this wonderful post. The TSOP receiver is a 3 pin IR receiver which detects 38 kHz frequency and generates a low voltage output to the timer IC’s trigger pin, with the timer working in monostable operation. In the receiver, there is a tone decoder, which responds well to whatever signals the remote sends at a carrier frequency of 38 kHz. When the sensor gets IR rays from the remote, the output of the sensor turns low and triggers T1. Most A/V equipment is IR based and has an IR sensor on the front panel. Next, press and hold the Return and Play/Pause buttons simultaneously for at least 3 seconds.
