Customer Reviews

  1. Review by Abram verified purchaser

    This is pretty good. I tried using jumper cables though and they don't work. The leads on the bottom are mainly for breadboard and pcb use. They're also quite fragile. Not the module, just the leads. It's a great, accurate solution for measuring temperature and humidity and is very reliable though! (Posted on 19/10/2018)

  2. Review by Ross verified purchaser

    Great for my weather sensing project. (Posted on 19/07/2018)

  3. Review by William verified purchaser

    Easy to use temperature and relative humidity sensor. (Posted on 16/07/2018)

  4. Review by LLoyd verified purchaser

    preparing the appropriate sketch to use this is at the moment a little challenging
    should have just bought the analogue one (Posted on 21/05/2018)

  5. Review by Kim verified purchaser

    Good little sensor but has an issue at high humidity, gets stuck around 100% and stays there. (Posted on 21/05/2018)

  6. Review by Rhys verified purchaser

    Easy to use, but you need a resistor. Seems to be very accurate. (Posted on 4/05/2018)

  7. Review by travis verified purchaser

    As described and good quality (Posted on 18/04/2018)

  8. Review by Nathan verified purchaser

    Fantastic product (Posted on 3/08/2016)

  9. Review by Rob - It just worked

    Connected this onto my Raspberrypi. Worked fine no problems at all. I was surprised at how close the temperature measurement was to my 1wire DS18B20 devices also connected to the RPi. (within 0.2 degrees between devices) (Posted on 22/05/2013)
