I'm an idiot my wife tells me every day. I'm trying to make a small device I'm going to strap on my drone to turn on a small light when I'm too close to the ground, for when I'm still playing around with it at night I have glow in the dark paint on it I can see IT but it's hard to tell when I'm too close too the ground and other objects. I'm thinking a pico or an adafruit trinket with a cr123 or a couple aa's to power it any help is appreciated it needs to respond fast. And again im an idiot I have limited experience putting Kali Linux on a pi.
How do you plan on doing the object detection?
I think a wire probe connected to a micro switch would work reliably.
I have not decided what sensor for object detection. Ir seems to be a possibility but I don't know if it's reliable enough, microwave radar is one but I don't know how cumbersome it is or anything, tof seems like a good one as well. I just want to figure out a reliable light weight low power sensor that's not too complex to utilize in this fashion. ToF seems like the most capable but I don't know how hard it is or really anything about utilizing it, or the weight or how much power it needs. If I could figure like an analog solution and design a circuit that powers a sensor that trips and turns on a light that would be awesome but that seems to be not at all possible or way harder than an Arduino and a sensor with 3volt battery and a fixture with a bulb. The wording of your question "what type of sensor for object detection." Indicates to me that I'd rather hear your thoughts as to what sensor I ought to utilize more than I want to tell you my ignorant thoughts on which to use.

I'm not sure I understand what kind of micro switch do you mean as well as kind of probe? Sorry like I said I'm an idiot I know my wife just told me yet again.
I mean any kind of microswitch you can somehow attach a long stiff wire to so when the end of the wire touches the ground the switch is moved to "on" and your light goes on. Then you know your thing is close to the ground.
I need it to wirelessly sense the ground. But I do like the way you think and I have another problem I was trying to solve that I'm going to try that on so thanks.
How much of your precious power are you willing to donate to the ability to continuously monitor the distance to ground? I also wonder about your use of an incandescent light rather than a LED.
Which MCU is controlling the drone? Does it have spare pins?
