In the industrial, medical and military and life and many other place, it needs to use the temperature measurement device to detect temperature. The traditional direct measurement wiring does not meet the requirements, especially in some environmental bad industrial environment and outdoor environment, through the direct wiring measurement is not practical. So using wireless transmission temperature testing is necessary. At present some design can realize the wireless temperature gathering, but the price is too high, its biggest weakness. In the actual temperature control process requires both system has stability, real-time and the need to reduce power consumption. So the design of a kind of low power consumption wireless temperature detection system is very meaningful. This paper presents a USES the monolithic integrated circuit AT89S52 control DS18B20 of the realization of the wireless temperature measuring system. Through the simple wireless communication protocol, realize the reliability and power balance, the system can realize to the temperature detection, can simultaneously determine the temperature, can be realized the wireless remote control temperature detection system. Low power consumption, real-time wireless temperature detection is the biggest characteristic of the design. Wireless transmission using nRF24L01 module transmission. The system structure is simple, reliable, low power consumption,
