DHT22 output calibrated digital signal. Small size & low consumption & long transmission distance(20m) enable DHT22 to be suited in all kinds of harsh application occasions. Single-row packaged with four pins, making the connection very convenient.
As you can see, the sensor size is so small when we compared with Malaysia 20 cent. Alternatively the size should be around our index finger size.
Note: Malaysia 20 cent is not included in the packing list. Picture above just for your reference only.
  • 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

Packing List:

  • 1 x DHT22 Temperature and Humidity Sensor
Hi, I've bought 2 of these sensors and have been using them for about a month now. I realize the the temperature readings goes off by up to 10 Deg C and humidity is mostly at 99.9 %rH. The same has been happening to both these sensors since I've started using them ( Justin, 31/10/2019 )
Hi, you may drop an email to support@cytron.io and our technical team will solve your problem. Thanks :)
When will restock? ( Mohamed Hakimi, 03/04/2019 )
Hi, it will available in 3 week. Please click on notify me button and we will send you an email notification once we have stock 
hai, does it necessary to connect 10K ohm resistor to the data pin to 5v supply?What are the effects if the resistor are removed? I check it does work without the 10K ohm resistor ( user, 17/05/2018 )
Hi, most of the tutorial advise to put a pull up resistor at the data pin in order to read the signal. In case you can read it without pull up resistor, then that's good. For further questions, please visit to our technical forum for similar question or post your question there, as this session is only for short inquiry. Thanks.
