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.
