Design And Construction Of A Remote Controlled Light Switch

ABSTRACT

IR LED emits infrared light, and used in TV remotes. This Infrared is received by the receiver TSOP 1738. TSOP 1738 receives the modulated Infrared waves and changes its output.

In this remote controlled switch circuit, a TV remote is used to ON/OFF the AC light by pressing any button of remote, and using the TSOP1738 at receiver end. Receiver circuit is connected to AC appliance via Relay, so that we can control the light remotely. We have used IC 4017 to convert it into a push ON, push OFF switch.
