  • Great device and works well

    posted by ImSir2U

    Works really well, a bit of false triggering but I'm told even the car manufacturer ones do this but I've never owned a car with one in before so I wouldn't know.
    The clamping system to hold them in makes it really hard to get them in by pushing on them, you need to pull from behind and use a twisting action to get them to seat flush with the bumper.
    Great product that works as well as you can expect for the money and I am going to buy another kit with black sensors for my other car if I can bring it over to this country.
  • Wire colors for the sensor

    posted by georgeangelopou

    Cheap dual (humidity-temperature) sensor. Thiw item can be functional as a humidity temperature sensor in grain storage rooms where both values are critical for conservation.
    I was a little worried because i could not find info on the web of the sensor. I bought one to check if i can use it. The plasic dismantled easily revealing the wire connections.HUMIDITY SENSOR : Blue and Green wireTEMPERATURE SENSOR: Brown and White wireNo polarity seems to apply. i will connect it with 1.5V and measure the voltage drop in variouw conditions. Hope it is usefull info
    I will buy more sensors as long as i find how to read the values. Though i just wanted to be helpful to other buyers i had to enhance my review in order to have it in order.
  • 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.
    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.
  • Soundproof little circuitboard

    posted by Gabriel94

    Cheap,great quality,easy to apply to arduino builds,small,usefull in small compartments and overall a great piece of tech for DIY involving sound
    This sound sensor I had for intentions of connecting to my laserballproject to match incoming music to the pattern in which the lasers would blink it worked perfectly.
    Great piece of tech for those in need of a sound sensor for their DIY and worked very favourably for my project.
  • its good

    It is very good goods. All works. All functions are present. This that that I wanted.
    Passive infra-red detector IS-215 / IS-215T the companies Р&- Systems (trade mark IntelliSense) provides reliable detection at the reasonable price. The optical system forms the dense diagram of an orientation with a zone of detection 12 х 12 meters, including two petals, directed directly downwards under the detector. IS-215 / IS-215T has the gauge of opening of the case, it is steady against influence of white light and a radio noise. The detector is compact, attractive, simple in installation and service. It can be established{installed} inside of a protected premise{room} both on a wall, and in a corner without an arm or on an arm.
