Effect sensors

Sensor is a detection device can feel the measured information. And can feel the information is detected, according to certain rules converted into electrical or other forms of information output required to meet the information transmission, disposal, storage, display, recording and control requirements. Achieve first link automatic detection and automatic control. Different points of view can be classified on the sensors: conversion principle (basic physical or chemical effect sensors work); use; output signal type and the production of its data and processes. It can be divided into physical sensors and chemical sensors two categories based on the sensor works. Piezoelectric effect, the sensor works free of physical sensor applications such as physical effects. Magnetostrictive phenomena, ionization, polarization, thermal, optical, magnetic and other effects. Small changes in the amount of the measured signal will be converted into electrical signals. The signal small changes in volume will be converted into electrical signals. Chemical sensors, including those with chemical adsorption, the electrochemical reaction phenomena such as causality sensor. We can not be divided into chemical classes. Most sensors based on physical principles of chemical sensors that operate based on more technical issues, some sensors can neither be divided into physics. Such as reliability problems, the possibility of mass production, prices, etc., to solve such problems, the application of chemical sensors will be a huge growth.
