| Abstract: | The LPC932 and nRF903 hardware connection and the communication protocol are mainly introduced.In order to reduce the power loss of the system,the function of LPC932 real-time clock may be used to realize the work and sleep function in turn,which saving electricity and reducing electromagnetic radiation to environments.LPC932 may be used in temperature-test system used in grain storages and any other systems needing observation and control of data transmission such as the small data network,safety protecting system,remote control system,toy,robot control and so on.The performance and characteristics of wireless communication chip nRF903 and the single-main-line temperature sensor DS18B20 are also introduced.A wireless temperature-test system for use in grain storages is constructed using monolithic integrated circuit LPC932,and its hardware constitution and software flow are specifically introduced. |
