Rightly pointed out by ASh, photodetectors(even cheap LDR's ) have very high sensitivity and require quite some calibration to work with. The problem I personally have faced here is the lack of branded photodetectors. Here they sell cheap local variants for Rs5 a peice. The problem is that, you don't get the manufacturer's datasheet. So you'll have to painstaikingly go through the calibration process on your own.ashOther things to take into account when selecting your photodetector is a detector which has a very quick response time and sensitivity in relation to the laser you choose. You'll need to do some research on this 😀
