摘要
针对当前实验室无法实现温湿度数据实时测量、数据传递不方便等缺点,以数字式温湿度传感器和通用单片机为基础,开发了实验室温湿度测量系统。该系统以AT89S52单片机为主芯片,数字式温湿度传感器SHT21为主要传感器,完成了测量系统硬件系统和软件系统的开发,并且设计了能够传递给上位机数据的通信程序。该系统可以实现温湿度测量,并且可以传递相关数据给上位机,对于实验室数据监测有着积极的作用。
Today the temperature and humidity data in real-time measurement and data transfer can not be realized in the laboratory and it is very inconvenient. So a temperature and humidity measurement system is designed based on digital temperature and humidity sensors and single chip. The system is based on AT89S52 microcontroller chip and the digital temperature and humidity sensor SHT21. Then the measurement system hardware and software systems are realized. This system can realize temperature and humidity measurements, and transfers data to the host computer. It is very helpful for data measurement in laboratory.
