    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:

    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.

    Cons:

    Would be nice if a datasheet was available. But you don't really expect that from these kinds of assembled components. Google HC-SR501

    OtherThoughts:

    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 ;)

    Bottomline:

    Value for money. Will buy again.
