The most versatile device in the Samsung SmartThings family, this sleek ZigBee device acts as a movement, vibration, orientation and temperature sensor all in one. The SmartThings Multipurpose Sensor can detect whether an object like a door or drawer is open or closed; sense when valuable or off-limits items have been moved or tampered with; offer temperature readings; and feel vibration. It requires the SmartThings Hub. SmartThings offers a one-year limited warranty on this product.
