2.1 Description
Figure 1: Radar proximity sensor block diagram
As depicted in figure above, the sensor comprises two printed circuit board assemblies (PCBA)
namely RF Board and Host Board which are connected internally through a board-to-board
connector. The sensor interfaces with rest of the system through an external connector which
brings power and system communication bus to the sensor. The sensor can operate from a
wide input voltage range, 12 – 36 VDC, and communicates with rest of the system over twisted
pair cable using Controller Area Network Flexible Data-Rate (CAN-FD) data-communication
protocol.
