Application of Wireless Communication in Multi-Channel Temperature Control System

Abstract:

In the technology of temperature measurement, the sensor is an important part of system. But with the increase of the number of sensors, it will undoubtedly bring with a lot of data cable. Compared with wired communication technology, wireless communications technology has the advantages of low cost, simple structures, low impact of environment. So the wireless communication technology meeting with the requirements of data communications has become a more practical, fast and efficient way. This paper describes a multi-channel temperature monitoring system using nRF905 wireless transmission module, STC89C52RC MCU and DS18B20 temperature sensor as core. Functions such as sampling, analysis, display, alarm and others can be done automatically by the system, dates transmitted by wireless module, and the system can realize the function of real-time monitoring of temperature.
