Design of indoor temperature and humidity monitoring system based on CC2430 and fuzzy-PID

Aiming at the actual demand of environmental information monitoring, an indoor temperature and humidity monitoring system based on fuzzy-PID strategy is designed. The system uses CC2430 as the core to develop wireless sensor nodes which follow the ZigBee communication protocol, uses the data collection terminal with high-precision temperature and humidity sensor to collect temperature and humidity data of the environment, uses ZigBee technology to achieve networking of wireless sensors and the automatic aggregation of monitoring data, and uses the fuzzy PID control algorithm to improve the accuracy of test data. The indoor temperature and humidity regulation is achieved based on fuzzy PID control technology. The management function of various sensor nodes and a large number of environmental data is achieved based on embedded database. The monitoring results for temperature and humidity have shown that this system is stable, high reliable in data transmission and easy to use, and can be widely used in various areas of automatic monitoring of environmental parameters.
