Design of Temperature and Humidity Detection System for a Material Warehouse Based on GM

In view of the measurement and control of temperature and humidity in the material warehouse of a factory, the Internet of things scheme is adopted, ESP8266 chip is used to connect WiFi, temperature and humidity sensor DHT11 is used to collect temperature and humidity, the collected temperature and humidity data is connected to Baidu intelligent cloud server through MQTT protocol, and the collected temperature and humidity data is sent to WeChat and stored in cloud through topic subscription and release of Baidu intelligent cloud According to, and at the same time use gray prediction model to predict the temperature and humidity data of the warehouse, through the WeChat end, you can view the current and predicted temperature and humidity data of the warehouse. The design of the measurement and control system is convenient and effective for real-time detection and prediction of the temperature and humidity data of the material warehouse. The system has the advantages of small size, low deployment cost and so on.
