Design of Wireless Multi-point Temperature Acquisition System Based on ZF01 Data Transmission Module

The traditional multi-point temperature measurements have many defects,such as the complex interconnection,the high demand for measurement environment.Because of the advantages of easy installation,small impact on the measuring environment,network flexible,the wireless multi-point temperature acquisition system using wireless communication technology has wide application value in the environment which needs multi-point temperature acquisition.This paper describes a wireless multi-point temperature acquisition system controlled by single chip microcomputer(SCM)based on wireless data transmission module ZF01 and digital temperature sensor DS18B20,and we also provide the system block diagram,principle diagram of the hardware circuit and the software flow chart.This system uses a TFT liquid crystal display touch screen as the man-machine interface,and SD card to save measure data.It is very easy to use,and has achieved good effect through the actual application.
