Sensor-Walk

 

 Both of these sensors detect movement, the black one controls the lock on the door while the white one controls the lights, turning them on if it detects movement or turning them off if it doesn't detect movement for an extended period of time.

This sensor is a little different. It has an on/off switch that is easily accessible to anyone in the room but if it is turned on and it goes a certain period of time without sensing any movement in the room it will conserve energy and shut the lights off anyway.

 

This thing is pretty nifty.  The sensor detects if there is anything under the water dispensor and if so it turns the water on allowing to fill your bottle.
