Description

SwitchBot Contact Sensors is made up of two components that are fixed close to each other on things such as doors and windows. With a detection range of up to 16.4 ft (5m), 90° horizontally, and 55° vertically, any movements that your door or window makes can be detected to help notify you when contact takes place.
