基于单片机的温湿度监测系统
Temperature and humidity monitoring system based on MCU
摘要
Abstract
The AT89S52 MCU and SHT11 digital temperature-humidity sensor are used to construct a temperature-humidity monitoring system with low cost. The data acquired and processed by 52-MCU is sent to LCD1602 for displaying. If the value of temperature or humidity exceeds the set valves,the sound and light alarms are generated by LED and buzzer. The system has simple structure,low cost,strong anti-interference ability,wide application range and low power consumption,and conforms to the trend of the instrument miniaturization,which lays the good foundations for the research and development of the intelligent micro temperature-humidity monitoring system.关键词
