Granary Wireless Temperature Monitoring and Alarm System Based on DS18B20

Abstract:

This paper introduces a Radio Frequency module based on the nRF905 all-digital granary wireless temperature monitoring system. The whole system adopts DS18B20 to measure the granary temperature, measurement data is processed by microprocessor MSP430 next, then carried out by the RF module nRF905 remote transmission, and displayed the measurement data through JHD1602. In addition to showing the temperature of the granary and alarming, the system can set up or modify the working parameters through keyword at control terminals. This system is characteristic of multi-point measurement, high-precision, wide rang of temperature monitoring, stability good and alarming timely, it may also apply in other related temperature control system, the versatility is very strong.
