Design of Multi-point Wireless Temperature Acquisition System

Feng Jin-liang

Abstract

This paper discusses the design process of multi-point wireless temperature acquisition system based on the nRF9E5,displayed the hardware program in which ATMEGA 16 is adopted as CPU,PT100 is used as temperature sensor,micro-power wireless module nRF9E5 is the system core,and analyzed the process of software in the system.Its operating distance is 100 meters under the circumstance of nothing blocked during the actual measurement.The steady performance,high reliability and the convenient collecting of node quantity in the extended temperature ranges as required made it possible to achieve wireless temperature acquisition in a large scope.
