## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    great little motion sensor
  

*by R***. on Reviewed in the United States 🇺🇸 on August 25, 2020*

very sensitive I used this to make a motion sensor fan when you walk into the room the fan comes on automatically

### ⭐⭐⭐⭐⭐ 







  
  
    Fixes all the problems of the larger motion sensors
  

*by Y***N on Reviewed in the United States 🇺🇸 on November 20, 2018*

These fix all of the problems the larger motion sensor have. Wireless signals do not cause false positives like they do with other motion sensors. I'm using these attached to esp8266 boards and have had no problems. I will definitely be ordering more!

### ⭐⭐⭐ 







  
  
    Application is limited
  

*by A***R on Reviewed in the United States 🇺🇸 on April 19, 2019*

It works, there is nothing wrong with it. The only problem for me was the lack of configurations, in particular, duration before shut off. There are other options for the same money that have pots to change sensitivity and duration, which also can be modded to run from 3V.
