Description

• 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. 
• Motion Sensor Detects Your Movements: With a motion detection range of up to almost 30 feet within 110° horizontally and 55° vertically, there’s more than enough range to secure an entire room of your home. You’re also able to customize the sensitivity settings so that you are only alerted to movements that matter to you. 
• Works Well with Alexa & SwitchBot Ecosystem: Connect sensors with other SwitchBot products and set up a “Scene” in the SwitchBot app. When you come home, SwitchBot Bot will automatically be triggered to turn on the light, and Alexa will say ”welcome home”. When you leave, SwitchBot Indoor Camera will automatically turn on to detect indoor activity while you’re away (SwitchBot Hub Mini required)
