Sorry @MMRIZE but I didn’t understand that the module “MMM-GroveGesture” was created by you and I apologize if I doubted its reliability.
I found the sensor you mentioned, in a nicer form to see, I am attaching the link:
https://shop.m5stack.com/products/unit-gesture-recognition-sensor-paj7620u2
Can you confirm that it is the same HW that you used?

Looks like so. (If the description is right). I think it is only housed with pretty cover. But I think its better without housing (Because you may want to dig this sensor to wooden mirror frame. In that case, without housing would be better to assembly)
Another possible issue might be HY2.0-4P Cable included. That connector would not fit with bare GPIO pins of RPI. You may need something like below cable (only one piece);

@Egnos said in Change page with MMM-Pages:

Furthermore, would it be possible to link the functions of the gesture sensor to a motion sensor (PIR)?
For instance:
IF the motion sensor does not detect movement THEN do not activate the gesture sensor (also because the monitor would be off …)
IF the motion sensor detects movement THEN also activate the gesture sensor (also because the monitor would be on …)

MMM-GroveGestures module already has onIdle and onDetected features, So these features could be used for your idle/wakeup behaviours. (But the sensor itself has not long distances like PIR, so to use PIR together would be better idea.)

If instead you took the sensor without a cover how did you think of attaching it to the frame? Do you leave the sensor naked or cover it with a self made cover?

Ok, I hope you will help me when I have to make it work!:winking_face:

From your tests what is the minimum distance that the hand must have from the sensor?

Thank you very much!

the doc for the sensor he linked says

Effective recognition distance 5cm-15cm
(without obstruction of case or cover)

If so, it is very little!

See how usage looks like.

I just have to try!

@Egnos
At this moment, I don’t have the real implementation to show,
But what I tried was;
Dig a hole then Implant the sensor in the frame. This gesture sensor has a short distance, but fortunately, through thin plastic/acryl/wood/paper/glass, it works. It detects changes in magnetic fields so except for metal/mirror(metal coated) it will work.
My first intention was to cover the hole with small cardboard paper, then paint it black (I prefer a black framed mirror), But I lost interest at the finish stage, so I left it naked. :D

Hi @MMRIZE unfortunately behind wood, plastic or plexiglass the sensor does not work … it’s a big problem!
Do you know by chance if this sensor has a SW adjustment (I don’t see any trimmer on the PCB …)?

thanks

By my test, under 5mm thick plastic or wood panel it works. But there is no s/w fixture about it.

I did several tests and even a piece of paper in front of it doesn’t work … it must be completely free …

I should try the glass …
