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


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


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


    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


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

    • One in package and the other out of it
