    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:

    Very cheap and relient item. I am surprised as sensitive it is. I like it and would order more for other projects involved motion detection. Easy to use motion detector with variable sensitivity and variable output-High time (2 sec ... few minutes).

    Cons:

    Doesn't has a CDS cell for to disable operation when ambient light levels are high. Board could be smaller If device so small - they should use SMD capasitors It would be great to have digital in\out on it - I2C...

    OtherThoughts:

    with these prices I might need to build more PIR sensor lights for my house.

    Bottomline:

    Good price, good quality
