Distance sensor behind dark glass

1

Hello everyone,

I search a distance sensor that works behind dark glass. I found ToF sensor, infrared sensor, but they can not work regularly behind dark glass and the distance can decrease.
I want a sensor that measures a distance of aprrox. 30 cm ~ 100cm from through the dark glass, but it must be work correctly.

Can anyone suggest me such distance sensors?

Many thanks.

Try recent GHz band radars, they are basically used for motion detection, but can penetrate walls. Probably, they can be set up for your usecase.

@hdhdhd Welcome!
But I have a question: Why do you ask on this forum ? What is the connection between SC/Particulate Matter and your sensor ? After we answer your question, will you participate in our project ?
