摘 要:本文设计了一种粮仓温湿度检测系统[1],给出了系统的硬件电路、软件设计思路。该系统是以单片机AT89S51为控制中心,采用SHT11为温湿度检测元件,实时监控温湿度的变化。单片机与传感器相连,采集并处理传感器的测量数据;通过LCD1602实时显示温湿度的数值;当温度或湿度超出预定值时则报警,从而实现对整个温湿度检测系统的管理。因此该产品具有品质卓越、传感精度高、抗干扰能力强、性价比极高等优点。24930 毕业论文关键词:温度;湿度;AT89S51;SHT11;LCD1602
Design of Detection System of Temperature and Humidity in Granary
Abstract: A detection system on temperature and humidity of granary is designed in this paper, consisting of hardware circuit and software design. The system can accomplish real--time control on temperature and humidity, taking AT89S51 microcontroller as control core and SHT11 as sensing element of temperature and humidity. Microcontroller and sensor are linked together, collecting and processing measured data with sensor. Real--time temperature and humidity values can be displayed through LCD1602. When temperature exceeds the preset value, the system will alarm, so as to management and detection the whole temperature and humidity system. So the product has excellent quality, sensor with high precision, anti-interference ability, high cost performance advantages.
