2 Channel Rf Remote Control Circuit Diagram. The proposed infrared or IR remote control circuit can be used to operate an appliance ONOFF through any standard TV remote control handset. Remote receiver decoder circuit.
This is a good solution for a unique and so interesting idea to wireless switching system to control the home appliance. In the above circuit the T1 of Switch1 S1 is connected to Normally Closed NC terminal of Relay. One of the weaks of Infrared is that the signal can not pass the walls.
The basic small-range remote controls are 2 Infrared and RF Radio Frequency.
This remote gives approximately 150 meter coverage by extending the ariel wire it can be increased up to 200 meters. Pin 14 is the input of the built in inverter inside the IC. RF Radio Circuits 26 Meters Detectors 63 Sound. And below ones showing the RF Receiver Circuit with Breadboard setup.
