@davidward no, its the disruptive wave of their presence as compared the space without them… logically same as the magnetic wave detection…

wasn’t there before, now it is

I got it. I was reading here https://www.derf.com/an-overview-on-proximity-sensors/ and question pop ups. Dust can be a bigger challenge to maintain sensors. How they can be protected? Does companies use any specific coating or something?

@sdetweil said in Capacitive Proximity Sensors:

@davidward basically the sensor detects a change in the wave shape in front of it…

the wave shape is not magnetic, but different… (I can’t explain that part)

So they emit any kind of waves?

I have read online that capacitive sensors can detect both metal and non-metal. Can anyone please explain me their working in simple terms? I read on various places online but information I found was too technical or less.
