hey guys,
First off let me start saying that i plan to make millions/billions with this design. But its missing a few key components, the first being a device that can measure the light intensity of a wall ~1m away.
Had a quick look and couldnt find what i need, wondering if you guys could help.
Basically i would like to sense light intensity at a certain distance. So i would point my sensor at the wall, and it would return the light intensity. When the light changes on the wall i should be able to detect this. The measured sample area should be small (ie narrow beam) and 50-100cm away.
I know there are devices out there that can measure the light intensity at the sensor, but i need to measure the intensity at the pointed object.
This can be best compared to those Sharp IR distance measurement modules, but i need to measure light intensity at the pointed object instead of distance.
Are there devices out there like this? Or how do i make one?
Thanks in advance for your help
p.s. if i get this going i'll be sure to put it up so everyone can make their own mil.
