- 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 output of TSOP1738 goes low then OK, your remote is of 38Khz type. Nothing to worry almost all TV remote are of this type.
- You can use any switch of the remote because for any switch the code only changes, the carrier frequency remains same. We need this carrier frequency only.
- Assemble the circuit on a good quality PCB or common board.
- The appliance can be connected through NO or NC and C contacts of the relay.
- Use a regulated 6V power supply for the circuit.
