  • Works great

    posted by ppsieradzki

    Really accurate! Like, very accurate, down to .5 degrees. This is fantastic if you're using it for something like a digital thermostat like I am. Really happy with this module and it even has a built-in LED that blinks when Arduino requests the temperature from it. Fantastic for diagnostic purposes.
    I'm using this as part of my home automation setup. I'm connecting this to an Arduino Mega (also purchased from DX) and the temperature it reads will allow Arduino to turn a relay on or off depending on the temperature which will give or cut power to the A/C unit in my room. Really handy.
    Fantastic value. With free shipping, this is by far the best deal on the internet.
  • Perfect little cheap and precise temp sensor

    Very tiny, digital, extremely precise and fast temperature sensor. Works over 1-wire bus. Ideal for DIY projects. Easy to hook up to a computer or microcontroller. In a passive mode just 2 wires are necessary.
    I bought 4 of them at first, built a simple 1-wire to RS232 adapter and used the SKU.24799 USB-RS232 adapter. It all works perfectly, reports temperature in 0.0625C degrees precision!I've built a home network of these sensors and measuring temperature in all rooms and basement. It's great!
    I am definitely buying more of them.
