Distributed temperature and humidity acquisition system based on STM32H745I

When I was growing up, there was no Internet to everywhere. In the past twenty years, the rapid development of technology has brought great convenience to our lives. In an era of network interconnection, we need to feel, integrate and utilize the convenience that the network brings to us. This time, in order to get closer to the network, we came up with this project - distributed temperature and humidity data collection system. As a centralized control system, the temperature and humidity data information scattered in various locations is collected into the system through WIFI network and wide area network, and saved; the temperature and humidity alarm value of each point can be set through the centralized control system. When the sampling data exceeds the set When the limit value is set, a light or sound alarm will be given at the sampling point. When you need to view data, you can connect to the centralized control system through the network, retrieve current data, and review historical data. The centralized control system uses the STM32H745I-DISCO development board + HLK-W800-KIT WIFI module. Don’t underestimate this WIFI module. This is also a development board and is not used as a data transparent transmission function. Main features: 1. Temperature and humidity wireless collection point (only 5V power supply is required) 2. MQTT transmission, collecting data and configuring sampling points 3. Independent centralized control system STM32H745I-DISCO4, data saving and historical data viewing 5. Host computer software connected to centralized control System 6, web configuration WIFI network
