Hello all smart drones!

Im looking for a sensor switch.  
I want to make a lip-switch that would work indoor/outdoors.

I found IR switches but they are sensitive to sunlight. I have also check ToF sensors but they are also not suitable for outdoor/sunlight. At least the sensors I have found.  Capacitive sensors trigger when it's raining/snowing.

Does anyone here have an idea of a sensor can be used as a lip-switch? I only need to detect On and Off. 

 

Thanks!

@andre-alm10 Have you looked into [surface acoustic wave systems]

My personal scorecard is now 1 PC hardware fix (circa 1982), 1 open source fix (at age 82), and 2 zero day bugs in a major OS.

@zander No I haven't but I will definitely take a look. 
I just got some information about a ToF sensor from BroadCom, APDS-9930. It works in sunlight and there is a card already made for testing with Arduino, available on Aliexpress. Maybe the drone bot would like to make a video about it. 😀

@andre-alm10 I can't speak for Bill, but I don't see how a Lidar could be a lip switch. I am not 100% sure what you mean by lip switch, but if you mean controlling a switch by a handicapped person with only their lips, I believe they work by blowing into a tube.

@zander I'm paralyzed from the neck and also a developer. I have developed many ad devices for myself. ToF can be used as Switch. Just measuring the distance to where you want the switch to go On and Off. 
You have one in your smartphones to detect your head and shut off the screen. The APDS-9930 is used in smartphones. If you are curious, I use a Gyro Headmouse and Sip and Puff switch for clicks. Sometime it would be great to have more switches, thats why Im doing this little project.

@andre-alm10 Well today I learned something. My limited knowledge of Lidar is from this forum and they were used for mapping rooms so I had no idea they were in my smartphone. I checked and my iPhone 14 does have it. I tried the app and my quick first impression is it is not very useful but it could be used to determine if my phone was held to my ear to hear. I never do that as I have hearing aids so I get audio via Bluetooth. I can't see it being good enough for your purposes, but it is worth experimenting.

BTW, my screen does NOT shut off when near my head but it's not relevant to me.

Yes, always good to have more tools, keep us informed of your progress.

@zander I haven't mention Lidar anywhere. Only ToF and it measure distance. If you put it on a rotating device you will get a Lidar or control the light with lenses.

@andre-alm10 Sorry, my ignorance is showing, I thought TOF and Lidar were the same or at least similar.
