Keyestudio RJ11 Easy Plug DHT22 (AM2302)Temperature and Humidity Sensor for Arduino Uno r3

The Keyestudio RJ11 Easy Plug DHT22 is a highly reliable digital temperature and humidity sensor designed for quick integration with Arduino Uno R3 setups. Featuring a pre-calibrated digital signal output and a plug-and-play RJ11 connector, it is ideal for South African students, educators, and makers building weather stations or home automation projects.

Plug and play RJ11 connection

This sensor breaks out the traditional four pins into a standard RJ11 crystal socket, allowing you to connect it directly to an EASY plug control board. This solderless design eliminates wiring errors, making it perfect for classroom environments and rapid prototyping.

Simple physical installation

Built with two integrated mounting holes, this compact module can be securely fastened to your custom enclosures, chassis, or educational rigs.

Calibrated digital signal output

The sensor utilises dedicated digital module collection technology combined with temperature and humidity sensing techniques to ensure long-term stability and high reliability. It delivers an ultra-fast response time and robust anti-interference performance.

Accurate temperature monitoring

Capable of measuring temperatures from -40 degrees Celsius to 80 degrees Celsius, this sensor provides a high accuracy level of plus or minus 0.5 degrees Celsius.

Full range humidity detection

The module measures relative humidity across a complete 0 to 100 percent range with an accuracy of plus or minus 2 percent. Operating on a DC voltage of 3.3V to 5V, it outputs a single-bus digital signal and weighs just 9.3g.
