Remote Operated Home Appliances Circuit

Suitable for operating, Lamps, Fan, Radio etc.., Small n easy unit

Here is the circuit diagram of Remote Operated Home Appliances or Remote controlled Home appliances. Connect this circuit to any of your home appliances (lamp, fan, radio, etc) to make the appliance turn on/off from a TV, VCD, VCR, Air Conditioner or DVD remote control. The circuit can be activated from up to 10 meters. It is very easy to build and can be assembled on a veroboard or a general-purpose PCB.

Remote Control For Home Appliances

Remote Control For Home Appliances


  • R1 = 220K
  • R2 = 330R
  • R3 = 1K
  • R4 = 330R
  • R5 = 47R
  • C1 = 100uF-16V
  • C2 = 100nF-63V
  • C3 = 470uF-16V
  • D1 = 1N4007
  • D2 = Red LED
  • D3 = Green LED
  • Q1 = BC558
  • Q2 = BC548
  • IR = TSOP1738
  • IC1 = CD4017
  • RL1 = Relay 5V DC

Circuit Operation:
The 38kHz infrared rays generated by the remote control are received by IR receiver module TSOP1738 of the circuit. Pin 1 of TSOP1738 is connected to ground, pin 2 is connected to the power supply through R5 and the output is taken from pin 3. The output signal is amplified by Q1. The amplified signal is fed to clock pin 14 of decade counter IC CD4017 (IC1). Pin 8 of IC1 is grounded, pin 16 is connected to vcc and pin 3 is connected to D2 (Red LED), which glows to indicate that the appliance is ‘off.’

The output of IC1 is taken from its pin 2. D3 connected to pin 2 is used to indicate the ‘on’ state of the appliance. Q2 connected to pin 2 of IC1 drives relay RL1. D1 acts as a freewheeling diode. The appliance to be controlled is connected between the pole of the relay and neutral terminal of mains. It gets connected to live terminal of AC mains via normally opened (N/O) contact when the relay energizes. If you want to operate a DC 12 volt relay then use a regulated DC 12 volt power supply for DC 12 volt Relay and remember that the circuit voltage not be exceeded more than DC 5 volts.

Just like our home and even the appliances that we have. Simple heat wave can cause burns and even fire that can burn your home sweet home. As a matter of fact, Summer heat forces many United States power businesses to lower voltage sent to your home. While this may not be an issue for most, you should still think about safeguarding your home appliances in order to stay away from needless expenditure and repair time. You can get a new appliance with a cash solutions. Source of article: visit at present on this online site.
