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

    Pros:

    Small Size, detects motion from 5+ feet which i tested, trimpots given for changing the sensitivity.

    Cons:

    The Plastic Lens case is very lightly attached.
    No datasheet provided in specifications
    Capacitors should have been SMD

    OtherThoughts:

    the Packaging should have been BETTER, as this can be easily damaged in transit.

    The Lens is NOT actual FRESNEL I think... there are simply Polygons inside, not sure if this is better or not than a FRESNEL Lens

    Bottomline:

    For the price, this is GOOD ENOUGH, works with Arduino... See the PIRSense Sketch

    • One in package and the other out of it
