The Design of Temperature and Humidity Monitoring and Alarm System Based on MCU
摘要
Abstract
Because of the complicated calibration problem of the classical analog sensors of temperature and humidity ,a new type of temper-ature and humidity monitoring and alarm system is designed ,which is based on a MCU AT89C52 and a digital temperature and humidity se-nor DHT11 .The system can display the temperature and humidity of environment on LCD at real time ,thus the monitoring function is real-ized .In addition ,the upper and lower limits of temperature and humidity can be set .When the temperature or humidity is beyond the limit , the system will alarm through a buzzer .The system is manufactured and can operate with high accuracy ,low power assumption and conve-niently .It can satisfy the temperature and humidity monitoring requirements in daily life and factory environment .关键词
