Remote controlled appliance switch circuit
adminSeptember - 17 - 200861 Comments
Description.
Here is a versatile remote controlled appliance switch that can ON or OFF any appliance connected to it using a TV remote.
IR remote sensor IC TSOP 1738 is used for recieving the signal. Normally when no signal is falling on IC3 the output of it will behigh.This makes Q1 OFF.When a signal of 38 KHz from the TV remote falls on the IC3 its output goes low.This makes Q1 conduct anda negative pulse is obtained at pin 2 of IC 1 NE 555.Due to this IC1 wired as a monostable multivibrator produces a 4 Sec long highsignal at its out put.This high out put is the clock for IC 2 which is wired as a Flipflop and of , its two outputs pin 3 goes low and pin 2goes high.The high output at pin 2 is amplified to drive the relay .For the next signal the outputs of IC2 toggles state. Result, we get arelay toggling on each press on the remote.Any appliance connected to this circuit can be switched ON or OFF.

Notes.
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 of38Khz type.Nothing to worry almost all TV remote are of this type.You can use any switch because for any switch the code only changes,the carrier frequency remains same.We need this carrierfrequency only.Assemble the circuit on a good quality PCB or common board.
The appliance can be connected through NO or NC and contacts of the relay .

Hi Javid 1 to 1.5mm bit can beused. Use 12 volt relay increase the supply to 12 volts DC add a 560 ohms 1/4 between supply atthe relay point to IC2 Pin16 in the positive rail. This will take care of the rest of the circuits

Hi Rakesh this can be used for any on/off application. for varying speed you have to add 4017 etc.

To Seetharaman,Thanks for the tips. By solving false triggering problem this circuit may be used for multipurpose switching.

Hi seetharamansubject: 100watt sub-wooferi shorted R9 & R10 the temperature of transistors decreased but Q7 is getting hotter than Q5 why ?
Replyseetharaman says:August 22, 2010 at 9:41 am
Hi Imteaz you can connect 100uF and a reverse biased diode in parallel with relay coil K1, this should solve your problem as theback EMF from relay coil is false triggering your IC.

Replyadmin says:September 20, 2009 at 11:54 pm
the load that can be connected to this circuit depends on the current capacity of the relay that you are using.You can get only one switching action from this circuit.More that one devices cannot be independently switched.
