摘要
为了粮食安全储藏和研究粮仓温湿度变化,设计了带时钟芯片DS1302的单片机温湿度记录系统。采用单总线数字温度传感器DS18B20进行温度采集,采用电容式相对湿度传感器HS1101进行湿度采集,将动态数据记录到STC89C54单片机内部EEPROM中。该系统运行正常,可以实时检测并记录温湿度,如检测到温湿度超标时则报警。
A system was designed for measuring and recording the temperature and humidity in the granary, based on STC89C54 and DS1302,in order to assure grain security. The temperature sensor make use of DSI8B20 as temperature test component, which is a single bus digital temperature sensor;the humidity sensor make use of HS1101, which is a relative humidity sensor;dynamic data is stored to internal EEPROM of STC89C54. The system worked properly, it can satisfy the requirements of real - time detection and record,it can give an alarm when the temperature and humidity is over standard.
