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

    Pros:

    There is all documentation for it: 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.
    The plastic lens is removable, so you can fit another or fit it differently.

    Cons:

    no light sensor, but you can put a Cds in it, it has free holes for it, go for R3

    OtherThoughts:

    This is small PIR sensor with many settings and upgrade options, go for HC-SR501 an you can find schematic, datasheet, pretty much everything about it.

    Bottomline:

    Unbeatable must have for the price. Even if you don't have use for it now, you can learn everything about PIR technology on it without fear of blowing something expensive.
