Sensitive sensor dispensing

It is a special electronic component that can sensitively sense certain physical, chemical and biological information and transform it into electrical information. This kind of element is usually made by using some sensitive effect of material. Sensitive elements can be named according to the input physical quantities, such as thermal (see thermistor), photosensitive, (Electrical) varistor, (pressure) sensitive, magnetic, gas, humidity sensitive elements. In electronic equipment, the use of sensitive elements to sense the information of the outside world can achieve or exceed the function of human sensory organs. Sensitive element is the core component of sensor. With the rapid development of computer and information technology, the importance of sensitive components is increasing.
Central control electronic components dispensing

Electronic components are the components of electronic components and small-sized machines and instruments. They are often composed of several parts, which can be used in similar products. They often refer to some parts of the industry, such as capacitors, transistors, hairsprings, clockwork, etc. The common ones are diodes.
