  • Human body touch sensor

    posted by hrpanchal

    I am using this product since couple of weeks and it is working fine. Its easy to use, attache and tiny.It is very sensitive to human touch. It is worth to buy at this price.I will buy some more sensors from dx.
    I guess, if it comes with some kind of touch plate will extend its uses.
    Less in price, easy to use and works excellent. If you are beginner you buy this kind of products.
  • Very nice movement detector sensor

    posted by margrilo

    It is very simple to use. It is very cheap (although it has a cheaper similar sensor in here: http://www.dx.com/p/ir-infrared-motion-detection-sensor-module-dc-5v-20v-139624)It is well made.It has two calibrations (timer and sensitivity)
    Very easy to use instead.Just plug the 5V and GND pins and the output is a HIGH/LOW signal.If movement is detected, signal goes HIGH.For other documentation on this sensor circuit board, you might wanna check: HC-SR501 on google
    It's a very usefull sensor for a plenty of projects.So for this price you might take two or three to have it with you and just plug and use when it become necessary

    it is cheapit is easy to install and useif you live in Brazil, I guarantee that it is fully compatible with PIAL PLUS system, I had installed mine and it is working fine. Maybe you have to accomodate the sensor box inside your wall but there is no big dealThe sensor has a screwcap so you can adapt to your needs. You can cut a little hole into your ceiling and install it. Nice, huh???
    watch out for the voltage, it is AC 100~265V and not 12v ok? If you pretend to use with LED you will have to use an adapter
    it is a good product, buy it!
  • great Device!!!!

    posted by spspider

    Firstly, a was very sad, because after connect a charger, the devise automatically call last binded number, then I send sms 0000, and 1111. The Devise turning off and switch on again. and work correctly.inside a devise all made in smd, and its wonder me - the plate is sophisticated!! all components soldered by modern machine.
    1. Insert sim2. call to sim, until Device automatically picks up you call.3.insert charger4. send sms 0000 then 1111 alternately
    in the future I try to remake it for my car, i will connect it to siren, throw controller(for calling function from alert of car to my phone), and connect alerting system of devise to car alarm(for turning car siren from PIR sensor)
