Design of the Wireless Multi-Point Temperature Gathering System Based on nRF9E5

This paper introduces the design of a wireless multi-point temperature gathering system,which is a typical application of WSN.The concrete method about how to design the system's hardware is given.DS18B20 is used as the system's temperature sensor,and RF SoC nRF9E5 is used as the system's key device.The programs' flow charts were analyzed,and a reasonable communication protocol was provided.Lastly,the test results of the system are showed.
