无线温湿度采集系统设计

Design of wireless temperature and humidity acquisition system

介绍了一种利用PT100热电阻和HS1101湿度传感器的无线温湿度采集系统的设计方案,采用C8051f330单片机配合铂电阻两线制测量电路和HS1101频率输出电路,2.4 GHz ISM频段射频收发芯片nRF24L01作为发送和接收无线通信模块,由CY7C68013结合无线通信模块作为接收机,通过USB将温湿度数据传送到PC机,并由LabWindows/CVI显示实时温湿度变化曲线。

Wireless temperature and humidity acquisition system using PT100 thermal resistances and HSll01 sensors is designed in this paper. The system uses C8051f330 microcontroller mating with two-wire resistance measurement circuits, HSll01 frequency output circuits, 2.4 GHz ISM band RF transceiver chips nRF24L01 as sending and receiving wireless communication modules, and the combination of wireless communication receiver modules and CY7C68013 as reeiever. The system uses USB2.0 to send temperature and humidity data to the PC, and displays the curves of LabWindows/CVI real-time temperature and humidity.
