Project description
This project demonstrates how to use the DHT22 temperature and humidity sensor with the W55RP20 EVB board, a one-chip solution combining the RP2040 and W5500. With minimal wiring, the project measures and outputs environmental data, making it an excellent starting point for IoT applications.
Wiring
- Data Pin: GP28
- Power: 3.3V
- Ground: GND
Project Highlights
- Reads temperature and humidity data from the DHT22 sensor.
- Outputs readings via the serial console.
- Provides error handling for sensor communication (timeouts and checksum validation).
This simple setup offers a robust example for integrating DHT22 with W55RP20, showcasing how the board can be used in sensor-driven applications.
