Remote data acquisition system based on GD32E231

LoRa technology occupies an important position in the development of the Internet of Things. Because of its ease of construction and deployment, it has become a commonly used dedicated network communication technology for the Internet of Things. In recent years, due to the leading position in the maturity of LoRa technology and the characteristics of LoRa's long transmission distance, low power consumption and strong anti-interference, LoRa modules are widely used.
This article designs to use GD32E231 to collect environmental data such as temperature, humidity, and infrared detection, and then transmit the data to the backend system through wireless transmission.
This design uses GD32E231C8T6 to control the temperature and humidity sensor DHT11, human body infrared detection module, OLED and LoRa communication module, etc. The adopted temperature, humidity and infrared alarm signals are displayed through OLED, and the data is transmitted to the LoRa node in the background through the LoRa communication node, and finally uploaded to the host computer.
