“I bought this to experiment with. Unfortunately I just haven't had time as I've been focussed on making an improved robot. It appears to be well made though.”
“Great PIR sensor for use as presence detector in a magic mirror (https://magicmirror.builders). Switches off the monitor whe no one is around for more than 2 minutes and turns it back on when triggered. The sensor has a very wide angle so 8t triggers the circuit as someone is approaching from the side too.
Setting potentiometers are quite sensitive but easily adjustable.”
