  • Good product some error in product description

    posted by andrjoha

    Relativ smal but the circuit boards could be smaler. and does what it should do. Only short time testing but, a nice product for the price. Bouth of the circuit boards has holes so easily fixed to something. The timing potentiometer could have a + and - for easier adjustment of the time.
    In my opinion and with a "couple" of years of experiens in electronics. The relay on the circuit board is marked with 12V DC, this means that the product description it says 5-24V. Tested the board with 6volts and the relay didn´t pull befor you tapped on it. If you go higher than 12V it could break. I would recommend 9-16V.
    I got this for testing purposes only but I´m preaty shure I will use it for a light project in the future. If you need a cheap IR-motion detector buy this.
  • 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.
  • Simply works

    Is what it says on the description. Very, very cheap for what it's worth, and includes a voltage regulator, so it works with 3.3V or 5V.
    BEWARE: It comes without any documentation whatsoever, so you'd better know what to do with it when it arrives. Google "adafruit bmp085", if you are interested, they have many great, simple to follow tutorials.
    Cheap, simple, effective. If you are into electronics DIY and own something like an Arduino or a Raspberry Pi, like me, its a must-buy.
  • Nice module to replace SR*04 from Para*ax

    posted by Yenary

    This module for the first time I have a little suspicious to use it. so i try to buy 4. after arrived i try this module. from the power and the measurement. this module act like SRF04 that the price 24$ more. in my country the module price was 30$. I think this item help me so much to produce a low cost and high accurate robotic automatic system
    Many aplication can make by this cheap and good item. I don't fine other trouble caused by this item.
    Thank you Dx for provide this item. So i could buy an inexpensive module for my project that have the quality like an expensive module.
