一般都希望传感器具有以下性能:(1)高性能(高灵敏度,高精度,线性、重复性好,响应快,互换性好,无迟滞,信噪比大);(2)高可靠性(寿命长,适应各种环境,破坏安全性好);(3)批生产性(小型,轻型,结构简单,廉价)。实际上全部满足上述要求的传感器是绝无仅有的。微型计算机与传感器结合可以弥补传感器的一些缺陷。例如:(1)对传感器本身的非线性进行线性化处理;(2)排除传感器的噪声;(3)自动校正传感器随时间变化的灵敏度和零点漂
Generally, the sensor is expected to have the following properties: (1) high performance (high sensitivity, high precision, linearity, good repeatability, fast response, good compatibility, Long life, to adapt to a variety of environments, destruction of safety is good); (3) batch production (small, light, simple structure, low cost). In fact all meet the above requirements of the sensor is unique. Microcomputers and sensors can compensate for some of the sensor defects. For example: (1) to linearize the sensor’s nonlinearity; (2) to eliminate the sensor’s noise; (3) to automatically correct the sensor’s sensitivity over time and zero drift
