OpenGarage Ultrasonic Sensor and Glass

[rgs]

Sorry for the noob question…

I’ve prepped two OpenGarage’s for installation and I’m now ready to mount them. My garage doors have glass panes at the top of each door.

Does glass affect the ultrasonic sensor?

I can avoid the glass but it just means that my installation is going to be farther from my garage door units. Thanks

I also have glass panes at the top of my door and it does not seem to matter. But you can test this just by holding the unit above the open door panes (don’t obscure the sensors with your hands) and watching the status on say your phone with the unit’s web page and look at the distance measurement and see if it makes sense and is stable. It does not need to be connected to the door opener yet for this to work. You do need to power it of course. I used a portable usb power pack.

Glass should be fine because the sensor uses ultrasonic waves (not light) to detect the door, so optical reflection does not affect the sensing.
