Design of wireless multi-point temperature transmission system based on nRF24L01

摘要

Temperature transmission technology plays an important role in the industrial production, but the security and reliability of data can not be guaranteed because of its difficult and complex wiring. As for these problems, this paper puts forward a wireless multi-point temperature transmission system with RF chip nRF24L01 for 2.4GHz band and high-precision 1-Wire bus digital temperature sensor DS18B20, and the system's hardware and software design is also discussed in this paper. The system can realize a real-time temperature transmission with C8051F340 microcontroller and the wireless transceiver nRF24L01. At the same time, the wireless transmission system can be achieved with low complexity and low cost. The test results show that the system has high accuracy and wide temperature range, which can reliably realize wireless data transmission.
