    REMOTE CONTROL FOR HOME APPLIANCES 

    S. MOHAN


    Connect this circuit to any of your home appliances (lamp, fan, radio, etc) to make the appliance turn on/off from a TV, VCD or DVD remote control. The circuit can be activated from up to 10 metres.

    The 38kHz infrared (IR) 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 resistor R5 and the output is taken from pin 3. The output signal is amplified by transistor T1 (BC558).

    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 LED1 (red), which glows to indicate that the appliance is ‘off.’

    The output of IC1 is taken from its pin 2. LED2 (green) connected to pin 2  is used to indicate the ‘on’ state of the appliance. Transistor T2 (BC548) connected to pin 2 of IC1 drives relay RL1. Diode 1N4007 (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 energises.

    First apply the ip voltage and identify the the relay working.After 230 volts phase will connect to relay No and Nc connect to bulb or any thing and nutrol- directly connected to bulb another point.

    no it cannot be used to switch multiple appliances a single circuit is used to switch a single appliancenotice that there is not a specific key on the remote control which is to be pressed any key can be done.

    becoz 15th pin is reset pin 4 is out put each time output is shifted means at a time only one pin is high all others r low when 4 is high this high output used to reset the ic so output shifted to first pin.

    Sugar cube 5V relays are easily available in Delhi. You cannot use 12V relay. If you want to use 9V DC supply you need a 7805 regulator in the circuit.

    Remove the Fan or bulb ON/OFF switch on the wall, extend the the N and L terminal from the switch and connect them to the N and L terminal of the circuit shown here. Now, you can control your ceiling fan using this circuit alongwith remote control instead of wall switch.

    Firstly, the video was uploaded by one of the readers, not by EFY. Secondly, extra two capacitors may be used as noise filter in the power supply line. Thirdly, the extra IC may be 7805 regulator IC, which is used to supply 5V to the circuit.
