  • Fantastic PIR module with included relay.

    - IR sensor works like a charm.
    - Trim regulator lets you adjust relay closing time.
    - Can be used with plenty varieties of voltages and powers, from simple AAA to powerful Lead-Acid batteries.
    - Separated sensor PCB gives you more flexibility when placing the sensor.


    - No range/sensibility regulator.
    - Relay makes a loud "click" when triggered.


    I'll upload some photos soon.


    I wanted to build an IR controlled 12V led light and I first tried with sku.139624 but I had no means of making it close a relay with its low output.

    Someone told me to fix my problem with a transistor, but since I don't have much knowledge of electronics he suggested me to buy this module with included relay.

    And, man, this is EXACTLY what I was looking for.
