Resistance, inductance and capacitance are the three major types of passive components in electronic technology, and a capacitive sensor is a sensor that converts the measured change into a capacitance change, which is essentially a capacitor with variable parameters.
Capacitive sensors offer the following advantages:
(1) High impedance, low power, only very low input energy.
(2) A large amount of change can be obtained, so as to have a high signal-to-noise ratio and system stability.
(3) The dynamic response is fast, the working frequency can reach several megahertz, the thick B contact measurement, and the measured object can be a conductor or a semiconductor.
(4) Simple structure. It has strong adaptability, can work in harsh environments such as high and low temperatures, strong radiation, etc., and is widely used.
With the development of electronic technology and computer technology, the shortcomings of capacitive sensors such as susceptibility to interference and susceptibility to distributed capacitance have been overcome, and barrier displacement sensors and integrated capacitive sensors have been developed: so it has been widely used in non-electric measurement and automatic detection, and can measure pressure, displacement, speed, acceleration, A-degree, thickness, liquid level, humidity, vibration, composition content and other parameters. Capacitive sensors have a good future.

Sick Sensors – An introduction to the photoelectric effect of photoelectric sensors
It is a physical phenomenon in which light irradiates certain substances and changes the conductive properties of the substance, which can be divided into three categories: external photoelectric effect, internal photoelectric effect and photogenerated volt effect. The external photoelectric effect refers to the physical emission of electrons from the surface of an object under the action of light.

Sick Sensors - Introduction to the static and dynamic characteristics of displacement sensors
Dynamic features:
The so-called dynamic characteristics of the sensor refer to the characteristics of the output of the sensor when the input changes. In practice, the dynamic characteristics of a sensor are often expressed in terms of its response to some standard input signal. This is because the sensor's response to a standard input signal ...

Sick Sensor – The difference between an infrared sensor and a laser sensor
Infrared sensors: Sensors that take advantage of the physical properties of infrared rays to make measurements. Infrared light is also known as infrared light. The infrared sensor does not have direct contact with the measured object during measurement, and the anti-interference performance is poor, so the lens needs to filter the infrared light before measurement, and it needs to be calibrated regularly.
