传感器是指通过物理的、化学的、生物的或其它方法把非电的物理量转换成连续电信号的一种电子部件。它除了敏感元件外,为了提高灵敏度、精度、稳定性,还必须附加放大、线性化、滤波、测试补偿等辅助电路,结构通常比较复杂,研制难度较大。这种传统的传感器,确切地说,应称为模拟传感器,它作为人类五官的延伸,是构成测控系统的首要环节,已经应用了多年,基本上满足了模拟检测装 Sensor refers to an electronic component that converts a non-electrical physical quantity into a continuous electrical signal by physical, chemical, biological, or other means. It is in addition to sensitive components, in order to improve the sensitivity, accuracy, stability, you must also add amplification, linearization, filtering, test compensation and other auxiliary circuits, the structure is usually more complex, difficult to develop. This traditional sensor, to be precise, should be referred to as an analog sensor. As an extension of human facial features, it is the primary link in the measurement and control system. It has been used for many years and basically meets the requirements of analog test equipment
