Centralite Micro Door Sensor

The Centralite Micro Door Sensor (3323-C) acts as an open/closed and temperature sensor in one. With SmartThings and the Micro Door sensor can send you an immediate alert if a door, window, or drawer opens unexpectedly, notify you if dangerous off-limits areas of your home have been accessed, and offer up-to-the-moment temperature readings.
