Design of Remote Temperature Monitoring System Based on GPRS

In this study, a kind of remote temperature monitoring system based on GPRS, used STC89C51 microcontroller is put forward as the host controller design, GPRS network as a remote signal transmission platform. The system can realize the measurement of temperature, also can realize the control of temperature to a certain extent. Using DS18B20 as the temperature detection element, the signal transformation was performed by A/D, and the system is showed by a high bright 12864 LCD. The testing results showed that the design can show the temperature of each point in time. When there are abnormal conditions, the parameters can be corrected and the number of detection units can be expanded.
