The motion sensor is simply a PIR sensor connected to a 434MHz RF transmitter via an encoder. The encoder uses four bits, in the form of resistors tied to HIGH (+VCC) or LOW (GND). That's enough for ...

The rover's arduino sends data that is collected from its sensors, using RF communication (NRF24 transceiver). A PC with another arduino and an NRF transceiver, runs the C# application. The ...

The creator of the Arduino RF Pro Mini open source development board Etienne, explains a little more about the inspiration behind the project. “ I’ve loved Arduino for years.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.
