In order to improve the efficiency of measuring temperature, remote measure, design a more intelligent wireless temperature monitoring system based on nRF4L01, the system is divided into two parts and from the host machine, the machine from the temperature sensor to collect temperature signals, in contrast with the collection value and the temperature control of temperature control. The working condition of the equipment at the same time, through the singlechip microcomputer control wireless transmission module to upload data to the host temperature chip for liquid crystal display. The experiment results show that the 500 m can realize the realtime acquisition and control of multi points temperature, the error is 0.5 degrees, and the work is stable, which can meet the functional design requirements.
