ABSTRACT

In order to solve the problems of complicated wiring and high cost in the existing indoor temperature and humidity monitoring system, an indoor temperature and humidity monitoring system based on CC2530 and fuzzy PID control strategy was designed and developed. The system consists of four sensor nodes, a gateway node and a monitoring center. It takes CC2530 as the core to develop wireless sensor nodes, and completes the real-time monitoring of indoor temperature and humidity. The communication between nodes follows ZigBee protocol, and realizes the self-organized network of wireless sensor networks and automatic aggregation of monitoring data. The system realizes temperature and humidity regulation based on fuzzy PID control technology and improves control precision. It uses embedded database management mode to realize sensor node management, environmental data management and early warning functions. The experimental results show that the system has good stability, high reliability of data transmission, strong adaptability, good openness, economy and short development cycle.
