摘要
设计了一个以C8051F020单片机为控制核心的温湿度数据采集系统,不仅介绍了C8051F020单片机、DHT21数字温湿度传感器和CH373-USB主控芯片等模块,而且给出了硬件组成和软件设计。通过C8051 F020单片机控制多个DHT21数字温湿度传感器,对干燥箱内多点实时监测,并由CH375-USB主控芯片,把检测的温湿度数据存储于U盘介质中,以实现数据存储操作。
This design is a temperature and humidity data acquisition system based on a single- chip microcomputer C8051F020, not only introducing the single-chip microcomputer C8051F020, digital temperature and humidity sensors DHT21, controller chips CH373-USB and so on, but also giving the components of hardware and the design of software o The single-chip microcomputer C8051F020 has controlled many digital temperature and humidity sensors DHT21 to monitor the temperature and humidity data in some spots of a drying cabinet in real time. And a controller chip CH373-USB has used to convert the temperature and humidity data into the U disk data storage media, achieving data storage operations.
