In the industrial, medical, military, life and many other places, all need to use temperature measuring device to detect the temperature. Traditional direct wiring measurement does not meet the requirements, especially in some bad industrial environment and outdoor environment, through direct wiring measurement is not reality. So the wireless transmission temperature detection is necessary. Some design can realize wireless temperature acquisition at present, but the biggest drawback is the high price.The system requires steadily and real-timing and the needs of reducing consumption.So it is very meaningful to design a low-power wireless temperate detecting system.This article presents a wireless temperate measurement which is achieved by using a STC89C52 MCU to control a DS18B20.The system can realize the remote control of the wireless temperature detection through a simple wireless communication protocol.It can reach the aim of reliability and power balance and measuring temperature.Low power consumption,real-time wireless temperature detection is the biggest advantage. The wireless transmission use nRF24L01 module.The system is a kind of wireless sensor solutions.It is simple structure,reliable and low cost.
