The PCB implements the recommended application diagram from the MLX90316 datasheet. The MLX90316DC (SOIC-8) is mounted on the board. It also includes an aluminum ring in order to center the magnetic knob (see below) above the sensitive area of MLX90316. By default, the output transfer characteristic is programmed to get a 10%Vdd ... 90%Vdd analog output swing for 0 ... 360 Degrees travel (complete revolution).
