Review on Optimized 433MHz Home Wireless PIR Infrared Motion Detector Sensor for Alarm System by KERUI by David Pirlet

Revainrating 3 out of 5

Works with Sonoff RF Bridge

I am using this with Sonoff RF Bridge. Works perfectly. I couldn't figure out the low battery code. It sends a message to the base in 2 seconds. An extension antenna is useful. I just wish there was a slightly better build quality.

Pros
  • weight
Cons
  • thin

Unstable, unreliable. Find a better alarm.
