There is no documentation for it. Google HC-SR501. You can connect CdS light sensor in it. It has two potentiometers and jumper pads so you can setup to suit your needs.
Would be nice if a datasheet was available. But you don't really expect that from these kinds of assembled components. Google HC-SR501
Works very well and is cheap. Get one even if you don't need it immediately. Even if you don't find a use for it later on, they're fun to play with ;)
Value for money. Will buy again.
