Research on Intelligent Temperature and Humidity Control System Based on MCU

An intelligent temperature and humidity measurement and control system applied to electrical equipments is designed in this paper. Design of this system covers signal processing, temperature and humidity acquisition, display and keying circuit, alarm circuit, and output control; these five sub-modules have realized its control function together. Hardware circuit design and system software application of various modules are illustrated in detail. According to practical test, software and hardware of this controller system match each other reasonably and the measurement accuracy is high. Besides, its design, development and maintenance are quite convenient, and the human-computer interface can be operated easily.
