With the improvement of living standards and the progress of science and technology, whether agricultural or requirement for temperature detection in daily life can request for a distance of transmission. Based on that this design is mainly based on MCS - 51 single chip microcomputer and the temperature sensor, wireless transmitter, LED digital tube and upper unit into synchronous display of temperature acquisition system solved the problems in daily life. Workplace sampling to temperature chip DS18B20 temperature to achieve the precision and accuracy, the last of the collected temperature data by module nRF24L01 wireless transmission and through digital tube display the current temperature controlled by single chip microcomputer, which can break the traditional operating temperature, is limited by distance of defects and easy to read temperature. After the hardware and software testing, we basically achieved with a temperature sensor to collect temperature, after a certain distance transmission with nRF24L01 in accept the PC software displayed on the model. Transmission distance 50 m, the
