Indoor Temperature and Humidity Monitoring System Based on WSN and Fuzzy Strategy
According to the characteristics of large delay and large inertia of controlled object in the indoor temperature and humidity, an automatic monitoring system of indoor environment based on wireless sensor network is designed. By placing sensors network nodes in monitoring area, the monitoring information is aggregated to the central monitoring system in order to achieve a unified data management and network routing monitoring functions. The real-time data in collected, processed and sent to the receiver by wireless sensor network. At the receiving end, the data is received, saved and displayed to achieve temperature and humidity monitoring and fuzzy control by which the best expected value is get to achieve automatic control of indoor temperature and humidity. The monitoring results have shown that this system is stable, reliable, cost-effective, high regulation accuracy, adjust quickly and small overshoot.
