粮仓无线温度测控及报警系统

Granary wireless temperature monitoring and alarm system

本文介绍一种基于射频模块nRF905的粮仓无线全数字温度监控系统。本系统采用DS18B20温度传感器对粮仓室温进行测量,并通过MSP430单片机把测量数据进行处理,然后由nRF905射频模块进行远距离传输,并且在测量端和监控端由JHD1602液晶显示出来,而且在控制终端设置有温度报警的输入键盘,可以根据现场需要设置温度区间,如有超出则自动报警。

This paper presents a Radio Frequency module based on the granary nRF905 all-digital wireless temperature monitoring system. It designs a temperature sensor on the granary DS18B20 measured at room temperature, meanwhile processing the measurement data by microprocessor MSP430, then carried out by the RF module nRFg05 transmission, and displayed the measurement data by JHD1602. Control terminals have a temperature alarm settings keyboard input; it will set the temperature range in accordance with the needs of the scene. It would automatically alarm, when the temperature have been out of the range.
