IoT System to control 433 MHz RC power sockets, PIR sensors, Door Sensors and much more.
Use NPM to install the platform on a RPi:
npm install iot-433mhz -g --unsafe-perm
Upload the single-arduino-tx-rx (https://github.com/roccomuso/iot-433mhz/tree/master/hardware-layer) sketch on your Arduino Nano.
Connect the 433 Mhz Receiver and Sender to the Arduino Nano, following this pinout:
And then connect the Arduino to the RPi through the Serial cable.
