摘　　要：为满足粮情测控系统实现全数字化的要求,研制出一种基于一线总线的粮情检测智能温湿度传感器。提出了以简单硬件电路结构为基础,通过软件补偿与校正技术提高传感器测量精度的方法。测试结果表明。In order to carry out the function of whole digital measure and control for the situation of grain store, a kind of smart temperature and humidity sensor based on one-wire bus and used for detecting the situation of grain store was developed. The methods based on simple circuit configuration with software compensation and emendation technique to improve the measure precision of this sensor was brought forward in this paper. The testing results showed that the sensor is on upper precision of measurement.
