Several years ago, I used some radar boards to detect movement.
After that I used a MMWave board
These are amazing, I’m using this in my Lab to switch on my big LED panel. You don’t need to move, it will detect human presence.
Another one I’m using in my living room.
It can power off all media at night (like TV, amplifier and lights)
It’s part of my home alarm system when we are away.
Now I got a new MMWave sensor, it can detect up to 3 persons and their location.
Screenshot from a Bluetooth phone app reading the sensor.
