This system is a solution designed for wiring difficulties, wasting resources,taking up the space and poor maneuverability of harsh environment industrial site , wide range and hi-tech agricultural field. Based on the above mentioned problems is proposed, which is based on wireless solutions of SoC design of wireless temperature gathering system. This system USES low power consumption, high performance microprocessor and single bus digital temperature measurement device DS18B20 constitute temperature measuring system through wireless transceiver, and finally in PC complete configuration, display and alarm function. Used in the design of the microcontroller STC89C52RC and MCS-51 MCU core has the same pin. But STC_ISP through STC89C52RC can burn to download software.Wireless data communication transceiver chip is an industrial grade NRF24L01 hardware link layer protocol built low-cost wireless transceiver operating in the 2.4 GHz band global open ISM. In addition, the temperature sensor DS18B20 to bus line digital mode transmission, greatly improves the power system.
