Sense your movements
With a detection range of up to 30 ft (9m), 110° horizontally, and 55° vertically, it can detect your body movements in a wide area.
Don’t worry about the perpetual notifications pushed to your phone, you can customize the sensitivity settings yourself! If Motion Sensor is set to be less sensitive, you will only be alerted to those conspicuous movements; a drama fly that idles its day by flying in your room here and there will never get into the spotlight to bother your phone.

Customers say
Customers find the motion sensor works well and is easy to set up, with one mentioning it detects both motion and light status. Moreover, they consider it reasonably priced. However, the functionality receives mixed feedback, with several customers noting it cannot be used as a Google Home automation trigger. Additionally, the lag aspect is also mixed, with some reporting consistent performance while others experience slow responsiveness. The notification capability receives negative feedback, with one customer reporting that neither presence nor absence events notify their phone.
