Hi nerdy geeky folks,
I have two questions:
1. can a regular cadmium-sulfide detect infrared in a complete absence of light (but a beam of infrared)? if not, what can be used to detect infrared (for a beam break sensor)?
2. I just want to make sure that I am building the circuit right...
Optics and bio research
hi yall!
im doing a neuroscience research on the circadian behavior of different species of fishes, and i need a device to measure activity levels of fish under different light conditions. one of the mostly used method is to have a light source (IR or something else)...
