Project description

This project tutorial demonstrates how to connect the W6300-EVB-Pico2 Ethernet development board with a DHT22 temperature and humidity sensor, and send real-time sensor data to ThingsBoard using the MQTT protocol. The W6300-EVB-Pico2, which combines the WIZnet W6300 Ethernet controller and Raspberry Pi Pico RP2040, enables reliable and low-latency Ethernet communication. In this tutorial, the DHT22 sensor is interfaced with the Pico2 to periodically read temperature and humidity data. The microcontroller formats the data into JSON and publishes it to the ThingsBoard cloud platform via MQTT…
