They're not accurate enough

Even after many adjustments, three out of five can miss the person walking directly in front of them half the time. I haven't tested the other two and intend to desolder the PIR sensor and build my own circuit instead.

Pros
  • Great for me
Cons
  • No instructions

Restricted use

It works, nothing wrong with it. The only problem for me was the lack of configuration, specifically the time to shutdown. There are other options for the same money that have potentiometers to change sensitivity and duration that can also be modified to run on 3V.

Pros
  • Very good price
Cons
  • Piggy bank Price

Fixes all large motion sensor issues

Fixes all large motion sensor issues. Wireless signals do not cause false alarms like other motion sensors. I am using these boards connected to esp8266 boards and have had no problems. I will definitely order more!

Pros
  • Hard surface
Cons
  • Was corrupted
