The sensor expansion card provides light, temperature, audio, passive infrared motion, dual axis acceleration and battery voltage sensing. As an option, 1 axis of the accelerometer can be disabled and replaced with a humidity sensor, Passive Infrared (PIR) motion detector or a servo output.


The pwr_ctrl pin is used to gate power to the sensor board (active low).
