摘要
利用单总线数字温度传感器DS18B20芯片以及微处理器,可以用软件方法实现对传感器由于环境温度带来的测量误差的补偿。文中以电阻应变式传感器为例,提出了具体的补偿方案。
A one-wire digital chip DS18B20 and microprocessor by software are used to modify the error caused by the changing of surrounding temperature when the sensor is testing. In this paper, a detailed compensation scheme about resistance stain type sensor is put forward.
