The Measure and Control System Design for Temperature and Humidity in General Storeroom

摘要

Based on the STC89C52 MCU as the core, this paper designs the measure and control system for temperature and humidity in general storeroom. The system includes two parts: hardware circuits design and software design. The hardware circuits include MCU smallest system, temperature and humidity signal acquisition circuit, keyboard circuit, LCD display circuit, control circuit and alarm circuit; the software includes main program and subroutines (temperature and humidity setting, acquisition, display and overrun processing, etc.). Through system function debugging, the system can realize the temperature and humidity information acquisition, display and control.
