With a detection range of up to 16.4 ft (5m), 90° horizontally, and 55° vertically, SwitchBot Contact Sensor detects your door/window open and closed. The magnet part of SwitchBot Contact Sensor needs to be aligned with the bottom of its main body, and the distance between the two components should be less than 1.2 inches (30mm).
*The data above is obtained from lab experiments conducted under 77°F (25°C)
Connected to SwitchBot Hub Mini, SwitchBot Contact Sensor pushes notifications to your phone when someone enters your home, when the window is open, or when your pet leaves the cage. It also works as an entry sensor for your safe home. With Contact Sensor on the door or window, your home security is taken care of by this watchful gadget and alerts will reach you in seconds even when you are far away. *Set in the app to stop your phone from ringing all the time you receive a notification.
When nobody's sensed first and the door is opened, you'll be taken as entering. Your light/AC/TV will be on automatically when you're home.
Small in size, easy to install, SwitchBot Contact Sensor can be placed on a refrigerator, pet cage, drawer, or a window to detect whether they are opened or closed. Make objects of all hues smarter by attaching a Contact Sensor to them!
