Human presence sensor (not IR)

[mackowiakp]

I'm browsing the project sources but I don't see support for a human presence sensor such as the LD2410 or similar.
I'm not talking about IR sensors, but Doppler radar sensors. Is it planned to introduce such a sensor into the driver set?

Yep, see pull request: https://github.com/letscontrolit/ESPEasy/pull/4852
And test builds for it: https://github.com/letscontrolit/ESPEas ... 6882140118

Ooo ! Very fine - THX for answer.

Oh... thats cool.

On their Homepage they claim "Directionality support".

Is it possible to detect if someone is moving from left to right or right to left?
I'd need something to check if someone enters or leaves a room.

If it is possible, I guess you can only detect moving closer or away from the sensor, not left/right from the sensor.
Then you probably need multiple sensors and use the data among them to triangulate the position.

For left-right movement detection, one approach can include using multiple sensors as per TD-er's suggestion. Another option that you can consider is using computer vision. You can use OpenCV. Following is an example of an hand tracking project using OpenCV and Micropython.
