基于SHT21传感器的智能加湿器设计

针对传统加湿器人工操作频繁、欠缺智能化的缺点,设计了一种以SHT21温湿度传感器为核心的智能加湿系 统。系统由湿度采集、中央控制、显示输出和加湿控制4个部分组成,利用89C51单片机对SHT21采集的数据进行处理, 系统依据处理后的数据对加湿过程进行控制,同时把数据反馈给显示装置进行可视化输出。测试结果表明,加湿器系统 能及时、准确的测量环境温湿度数据,并根据系统预设值,控制加湿器正常工作,实现加湿器智能湿度控制的目的。

Design for Intelligent Humidirier Based on SHT21

iming at traditional humidifier manual operation frequently and lack of intelligent, designed the intelligenthumidifying system based on SHT21 sensor. The system consisted of four parts including humidity acquisition, centralcontrol,display output and humidification controls, processed data from SHT21 by 89C51 single chip microcomputer,controlled the humidification process based on processed data.at the same time feedback data to the display device forvisual output; the result shows that this system can measure environmental temperature and humidity data accurately.control humidifier work normally and realize the purpose of intelligent humidity control.
