Description of product: Sensor of temperature and humidity DHT22 (AM2302) - module + cables

The module includes a popular sensor for measuring temperature and humidity. On the board are also, required for proper operation of the system: a resistor and a capacitor to filter the supply voltage. The sensor can be controlled using a microcontroller or any commissioning set, for example, Arduino. Before using, you need to see the documentation.


The product is compatible with Arduino

Library and connection diagram with Arduino can be found on this address.

User manual can be found onour website.


Pins are popular goldpin connectors (2.54 mm pitch) for connecting the sensor via wires or to directly attach to the breadboard. The set includes three colorful wires.


Connection example

The system contains passive components necessary for the proper operation of the sensor. The module is sufficient to connect via wires, to any microcontroller in the following way:

  • VCC ( + ) - supply voltage from the range: 3 V to 5.5 V
  • GND ( - ) - the ground of the system
  • OUT- digital output connected to the input of the microcontroller

It works stably and accurately
Benedykt 08.09.2022 Confirmed purchase Translated review
the sensor uses it for the weather station works great, I recommend it
CZESŁAW N. 11.05.2022 Confirmed purchase Translated review
works as intended
Piotr A. 09.04.2022 Confirmed purchase Translated review
I recommend
Krzysztof K. 20.02.2022 Confirmed purchase Translated review
It works very well. I compared it with a non-contact hand thermometer and the difference in measuring the temperature in the room was approx. 0.2 degrees. I believe that is a pretty good result
Radosław M. 21.01.2022 Confirmed purchase Translated review
Everything is 100% functional and perfectly matches the temperature / humidity design
Mateusz R. 01.11.2021 Confirmed purchase Translated review
The sensor is well made. The only drawback that I noticed is that it is very easy to bend it away from the plate, which in the future may cause the sensor pins to break
