Description
Need a temperature and humidity sensor for a Raspberry Pi weather station? This HiLetgo DHT22/AM2302 module is a compact digital sensor for reading relative humidity and temperature in beginner electronics and connected-project builds.
Why it suits a Raspberry Pi project
- The DHT22/AM2302 is the sensor used in our Raspberry Pi weather dashboard example.
- A three-pin breakout module can simplify connections for power, data and ground when paired with suitable jumper wires.
- Readings can be collected by a Raspberry Pi and sent to a REST API or displayed locally.
Compatibility and wiring notes
- Check the module’s printed pin labels and your chosen Python library before connecting power; board layouts can differ.
- Use a safe 3.3V GPIO setup and follow the wiring diagram in the project guide.
- This is an electronics module, not a weatherproof outdoor sensor. Use suitable protection for outdoor experiments.
See the Raspberry Pi weather sensor dashboard guide for the role of the sensor in a complete build.
