Fun Remote Control Light Switch Circuit Diagram

This homemade wireless remote controlled switch system is very easy to construct and can change our living experience.

Remote control light switch circuit diagram. Circuit diagram of remote controlled switch. So we have connected a 1uf capacitor across the output of the tsop so that this 38khz pulse train is counted as one clock pulse to the ic 4017. Tsop1738 used in the circuit for detecting ir signals from the remote.

Before wiring the circuit make sure that the carrier frequency of the tv remote you have is 38 khz for that wire the sensor part only point your remote to the tsop1738 and press any switch if out put of tsop1738 goes low them ok your remote is of 38khz type nothing to worry almost all tv remote are of this type. Output of tsop1738 oscillates at the rate of 38khz which is applied to clock pulse of 4017. This is a schematic circuit diagram of a remote controlled switch for home appliances.

Ir infrared remote controlled switch circuit diagram for light fan appliance. Tsop1738 is used in the circuit for sensing the infrared signal output from remote. In this circuit there are two relays are used the first relay is used for giving input signal to ic according to changing pulse from the sensor the second relay is used for connecting load ie fan light etc.

Before wiring the circuit make sure that the carrier frequency of the tv remote you have is 38 khz for that wire the sensor part only point your remote to the tsop1738 and press any switch if out put of tsop1738 goes low then ok your remote is of 38khz type nothing to worry almost all tv remote are of this type.
