The mLink DHT22 sensor is a serial (I2C/IIC) temperature and humidity sensor module. It adds the ability of your microcontoller/Arduino to measure temperature (in oC) and relative humidity (%RH) to 1 decimal place using only its I2C interface. It is compatible with other mLink or standard I2C modules allowing you to daisy-chain several different types of modules together using only the two I2C pins of your microcontroller.

For Arduino users you can use the mLink library (see below) to control any type of mLink module. Only one single instance of the library is needed to control multiple types of mLink modules resulting in very little resources overhead and therefore making it great for Arduinos with small amounts of memory and pin counts.

David ★★★★★

I plugged this into my breadboard project and the serial connection was recognized instantly by the Arduino IDE—no fiddling with extra libraries needed. The temperature readings are stable and match my reference thermometer within 0.3°C, which is exactly what I needed for my fermentation chamber.

Natalie Y. ★★★★★

Was looking for a temperature sensor with reliable humidity readings, and this module delivered both right out of the box. The serial I2C interface makes wiring straightforward, and the data is consistent compared to my old DHT11.

Hannah ★★★★★

The I2C interface made it super easy to integrate with my Arduino—just two wires and I was getting precise temperature and humidity readings within seconds works perfectly for my weather station project.
