ir remote switch circuit

Posted on Feb 4, 2014

This circuit lets you control any line powered electrical device (a lamp, television, fan, etc. ) using any infra-red remote control. Almost everyone these days has a pile of old IR remotes left over from appliances they have long ago disposed of them. With this circuit, you can put them back into use. The circuit looks for any modulated IR source

and uses it to control a TRIAC, which then switches any appliance connected to it`s socket. For example, you can use it to control the room lighting in your home theater setup using any of the remotes you already have. The circuit is powered using a simple transformerless power supply from the line itself, making it compact and easily built into a light switch, wall box, power bar or even the appliance you wish to control.
