Introduction

The Demo uses the GD32E230 analog IIC to read the data of the T/H sensor and the illumination sensor respectively, and then sends the data through the LORA module.

The implemented features include:

• Temperature And Humidity Acquisition
• Illuminance Acquisition
• LORA TRANSMIT

Quick start
