Device is build from 3 boards :

Battery powered transmitter power supply , a DC-DC step up convertor providing 13 V DC to the beam transmitters.

Receiver front end, it distribute the DC power from the control unit, and transmit the sensors signals over RS485. The board include a DC-DC step down converter to power the RS485 circuit.

Controller unit, including the processor, DC-DC step up converter to power the sensors and DC-DC step down converter for the uC and other circuitry.
