Humidity and Temperature Sensor - DHT22
 

The DHT-22 is a low cost humidity and temperature sensor with a single wire digital interface. The sensor is calibrated and doesn't require extra components so you can get right to measuring relative humidity and temperature.

Features:

  • 3.3-6V Input
  • 1-1.5mA measuring current
  • 40-50 uA standby current
  • Humidity from 0-100% RH
  • -40 - 80 degrees C temperature range
  • +-2% RH accuracy
  • +-0.5 degrees C

  1. Nice product, awkward packaging

    Posted by on

    I would probably order the cased one next time as I didn't realise this is really meant to be PCB mounted... otherwise performs as specified and does the job!


  2. certainly does the job...

    Posted by on

    once I had sorted the arduino code directories on the PC, all went to plan, then ported to the Raspberry pi, and same again, care with directory structure, and all was well.


  3. Easy to use and accurate

    Posted by on

    More stable than a TMP36 and with added humidity. I found the TMP36 had to be averaged out but this sensor is steady.
    A great little sensor for those starting out Arduino or Raspberry Pi. Either upload the data or put on an LCD display.
    A little pricey but worth it.


  4. easy to integrate

    Posted by on

    very helpful company, excellent sales and tech team


  5. Good, but expensive

    Posted by on

    The RHT03 (the actual product supplied, which is identical to the DHT22) is quick, accurate, and works on a single wire - but it's also pretty expensive.

    There's a full review - plus a link to an Arduino library for communicating with it - over here:
