Hi folks, I'm absolutely new to the forum and Arduino world would really appreciate if you can help and teach me sth
I was reading about this sensor here:
It says It out puts a square wave proportional to the light intensity. So if I have a laser emitter (1mW) am I able to use inverse-square law to estimate the distance of an object with it?
I can clearly see the leaser beam gets larger in the far field distance and did a bit study it seems real world lasers have "Laser irradiance"(not sure but I guess and I don't know the model of my laser but it is 1mW red laser AFAIK).
Could you please teach me a bit about why it is/is not possible?
Thank you so much
