Présence sensor

[ionic ravine]

I need a trustworthy presence sensor

[frail niche]

trustworthy in what sense? there are ways to get around problems with motion sensors, but for presence radar sensors may be what you need. or a combination.

i have ordered a radar sensor from apollo that is in shipping so no experience with it yet

mmWave is better for presence than a PIR

As always though:
