? Let me answer; Sensors and how they work ? Precision Tube Sensor (Sensor) is a device that converts non-electrical signals, such as physical, chemical, or physiological quantities, into electrical signals, and its main role is to convert external environmental changes into digital or analog electrical signals so that computers, microprocessors, and other digital electronic equipment can be identified, processed, and controlled.
Precision Tube Sensors Working Principle: Sensors are usually composed of specially designed physical quantity sensitive components, signal conversion circuits and processing circuits and other parts. Its overall workflow is as follows: feel the external physical quantity: Precision Tube Sensors sensitive components contact with external physical quantities, such as pressure sensors in the piezoresistive material, temperature sensors in the thermistor, etc.. These sensitive components can feel the external pressure, temperature, humidity, electric field, magnetic field and other specific physical quantities, and will be converted to the corresponding electrical signal output. Signal conversion.

Let me answer; Precision Tube Sensors have signal converters that convert the above output electrical signals into signal types more suitable for processing and control systems. These signal types include analog voltage/current signals, digital pulse signals, etc.? Processing and Amplification: The converted signals are fed into the sensor's processing circuit board, where filtering circuits may be required for signal denoising, and gain circuits may be required to make the processed signals more accurately fit the desired controller. Output: The final sensor outputs the processed signal to a computer, microprocessor, or other digital electronic device for data processing and control. By analyzing and interpreting the sensor output data, digital devices can be made to realize the perception and response to the external environment. Based on different working principles and different choices of physical sensitive components, we can divide common sensors into the following categories:? Chemical sensors: used to detect specific chemical substances in gases or liquids, such as carbon dioxide sensors, oxygen sensors and so on. Their sensitive elements usually use electrochemical cells, semiconductor materials, etc.? Optical sensors: use optical principles to detect the optical properties of the measured object, including reflection, transmission, absorption, etc., such as photoelectric sensors, infrared sensors, etc.? Sound Sensor: Used to sense the surrounding sound changes, input to the relevant equipment for signal processing and control. Displacement sensors: used to detect the position or movement of objects, such as magnetic induction displacement sensors, piezoelectric displacement sensors, etc.? Measurement sensors: used to measure the size, weight or shape of the object and other characteristics, common blood pressure sensors, weighing scales and so on. In summary, Precision Tube Sensors? is a class of devices that convert physical quantities into electrical signals. They sense changes in the external environment through sensitive components, and through conversion and processing circuits will be converted into digital or analog electrical signals output to computers and other digital electronic equipment for control and processing.
