    One more thing…
    To work properly…give 12 v supply..
    5v doesn’t work well


  2. ASHIM KUMAR DAS (verified owner)

    But the set which comes with 4 electrolyte capacitors at four sides…is good…
    Sometimes same set without capacitors are also sent, they’re not so sensitive…
    Please keep it in mind…

    Works good


  4. sriharidayalan (verified owner)

    robu satisfy your needs


  5. saharsh.bhadani (verified owner)

    Works well as expected. If there is temperature then the sensor returns high. I think no temperature at all will keep the sensor low.

  24. dhaval (verified owner)

    Have not used this yet in my project. packaging was good and delivery was quick. just one thing i would like to mention is that the description states that single /multiple trigger jumper is available, whereas the actual product has no such jumpers. just two solder pads for us to permanently select single or multiple trigger
