Abstract

Surface temperature is an important parameter commonly used in thermal infrared remote sensing. Precise measurement of temperature is one of basic tasks in ground parameter acquisition. A remote high precision temperature acquisition system based on GPRS is presented in this paper, which consists of a STM32 MCU acting as main controller, a temperature measurement module made up of PT100 sensor and AD7787, a wireless data transmission module using Neoway GPRS chip as core device, and auxiliary modules such as OLED display, Micro SD card memory, RS232 configuration interface. The paper describes in detail the Pt100 3-wire temperature measurement method, circuit design and software controlling of the system. Test on the system was done and results indicate that thermomeric error of this system is less than 0.20C. The system has function of remote data trasmission, so can easily realize unattended temperature collection in field applications, taking advantage of low-cost and labor-saving, and is expected to have good practical values.
