Relay control by remote control


Functional Description:

  • Relay and power control via remote control.
  • The transmission medium is an infrared diode on the remote control (transmitter) and on the receiver - module KY-022.
  • The received signal can be decoded and assigned a specific action that is controlled by Arduino. Measure the quantity, send it to the server. Turn on output, lighting, boiler, drawer on demand, perform time action, sequence.
  • Use is simple and versatile. The receiver range is up to 10 meters. Can be used for various protocols: NEC, RC5, RC6, SONY, JVC.
  • Used hardware:

  • Arduino Nano Arduino Nano
  • KY-022 receiverKY-022
  • Remote control SILVERCREST KH 2159 SILVERCREST KH 2159
  • 8-channel relay 8-channel relay
  • Exploitation:

  • Remote light control
  • Open Garage / Entrance Gate on Demand
  • On Demand Measurement
  • Wireless toy controls (RC technique, custom projects ...)
  •       

    Source code with header file IRremote.h for signal loading and 1x relay control:

          
  • Return codes are from one button. Returns 820, 20 alternately for repeated presses. The same code repeated under RC5 is repeated when you hold down the button.
