The Research and Design of Wireless Temperature measurement system based on nRF905

Abstract

In modern production and life, temperature is an important parameter in many occasions.In many places, it is necessary to monitor the temperature parameter and making relevant processing so that the system runs in the best state. Therefore, it is significant to develop a reliable and practical temperature monitoring system. With the rapid development of wireless transmission technology, short range wireless transmission technology has been widely applied to many places where wiring is not available, offering great conveniences for people.

This paper introduces the temperature measurement system based on nRF905 wireless transceiver module, 80C52 microcontroller,DS18B20 temperature sensor.This paper puts forward that the wireless temperature data acquisition system is built with the RF transceiver chip (nRF905) as the core, and its guiding ideology is modularization, The system is consists of collection module and wireless transmission module. The data acquisition module detects temperature data with digital temperature sensor DS18B20, then the simply processed data is sent out by the RF transceiver chip (nRF905).Wireless transmission module sents, receives and processes data by the nRF905 chip.Finally the data is sent to PC through the level converter chip MAX232.
