We use these around the lab:
It's a small photodiode sensor board with an amp and some minimal logic.
Puts out both analog (continuous) signal and thresholded level (on-board
pot). Hard to beat for ~$5 assembled... You can cut the traces powering the
LEDs if they cause problems with experiment, but useful for debugging..
