Based on the ZigBee wireless transmission technology, the system chooses the intelligent solution of TI company, taking CC2530 as the control core. It realizes the data acquisition of temperature and humidity through DTH11 sensor. The MySQL database is used to store the temperature and humidity information, and the functions of server side data display, query and dynamic analysis are realized. In addition, users can send control commands remotely on servers and mobile application terminals by preset thresholds, change the level signals of the corresponding I / O ports, and automatically call control modules to adjust the state of devices such as relays, infrared transmitters, etc. In order to change the heating, cooling, drying and humidifying state of the controlled appliances, the remote operation of the temperature and humidity monitoring system is completed.
