Window & Door Alarm Sensor for Home Security
SwitchBot Contact Sensor can detect the opening/closing of doors and windows, guarding security of the elderly, children, and pets. With the built-in light sensor, it will automatically trigger the Switchbot Bot to turn on the light when someone moves when the environment goes dark.
Detects People Leaving or Entering the Home
With the built-in motion sensor, Contact Sensor will know whether you are leaving or coming home, making it possible to trigger the different actions you set in the "Scene" in the SwitchBot app.
Easy to Install & Place It Anywhere
Thanks to the small and wireless design with long battery life, you can install Contact Sensor tool-free and get it set up in seconds.
