Sensors

A sensor is a device or apparatus that can sense the measured object and convert it into a usable output signal according to a certain pattern. Sensors generally consist of four parts: sensitive components, conversion components, conversion circuits, and auxiliary power supplies. The functions of sensors are often compared to the five major sensory organs of humans: Photosensor - Vision Sound sensitive sensor - auditory perception Gas Sensor - Olfactory Chemical Sensor - Taste Pressure sensitive, temperature sensitive, fluid sensors - tactile Classification of sensitive components: Physics based on physical effects such as force, heat, light, electricity, magnetism, and sound. Chemistry is based on the principles of chemical reactions. Biological class, based on molecular recognition functions such as enzymes, antibodies, and hormones. Usually, according to their basic sensing functions, they can be divided into ten categories: thermosensitive elements, photosensitive elements, gas sensitive elements, force sensitive elements, magnetic sensitive elements, humidity sensitive elements, sound sensitive elements, radiation sensitive elements, color sensitive elements, and taste sensitive elements. The characteristics of sensors include miniaturization, digitization, intelligence, multifunctionality, systematization, and networking. They not only promote the transformation and upgrading of traditional industries, but also have the potential to establish new industries, thus becoming a new economic growth point in the 21st century. Miniaturization is based on Micro Electro Mechanical Systems (MEMS) technology and has been successfully applied to silicon devices to make silicon pressure sensors. Advantages of glass encapsulated connectors: widely used in dew point meters, power equipment, IoT devices, aerospace connectors, coal mining and oil exploration equipment, to achieve data collection and transmission.
