Review on HiLetgo 3pcs AM312 Mini Pyroelectric PIR Human Sensor Module Infrared IR Sensor Body Manual Motion Infrared IR Detector by Chris Horton

Revainrating 4 out of 5

Got 3, the tags are a bit sloppy!

I would like the pin marking on the board to be clearer (not the same as in the photo). One out of three boards burned out due to incorrect pin guessing. The other two boards worked fine, latency is instantaneous (that's what I was looking for, so everything is fine!). The output voltage is quite low, only 1.556 V DC, the LED barely registers; You need to connect a transistor for more functionality.

Pros
  • Pretty package
Cons
  • I don't remember
