About this item

• [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. When it detects you leaving home, the appliances will automatically turn off, and when it detects you coming home, the appliances will automatically turn on. (SwitchBot Hub Mini required)
• [Home Security Alarm Sensor for Windows and Doors] The SwitchBot Contact Sensor is able to determine when doors and windows are opened or closed, providing security for vulnerable members of the household. Equipped with a light sensor, it will activate the Switchbot Bot to illuminate the area when motion is detected in dark conditions. Ensure proper alignment of the magnets at the bottom of the unit, keeping the distance between components under 1.2 inches (30mm).
• [Part of the SwitchBot Ecosystem] Connect Contact Sensor with other SwitchBot products and set up a ”Scene“ in the SwitchBot app. When windows are opened, the SwitchBot Bot will be triggered to turn off the Air purifier automatically. (SwitchBot Hub required)
• [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. Place it on a medicine box to track whether the elderly are taking their medication, or place it on your pet's cage to know if your kitten has slipped away.
• [Remote Alert Notification & Voice Alarm from Alexa] You will receive a door-open alert notification on your phone if a suspicious person enters the house while you are away (SwitchBot Hub required). Alexa will start a voice alarm to scare off any burglars, ensuring your apartment security.
