Search on WeChat Technical Training Sensors are tools for humans to perceive, acquire, and detect various information from nature, enabling the collection of vast amounts of information that human senses cannot obtain. In modern science and technology, industrial and agricultural production, and daily life, sensors play an irreplaceable role.It can be said that the more … Read more
1. Working Principle Sensors are generally composed of four parts: sensitive elements, conversion elements, conversion circuits, and auxiliary power supplies. 1. The sensitive element directly senses the measured quantity and outputs a physical signal that has a definite relationship with the measured quantity; 2. The conversion element converts the physical signal output by the sensitive … Read more
