Specification

The utility model relates to a detection device, which can feel the measured
information and convert the sensed information into electrical signals or other
required forms of information output according to a certain law, so as to meet
the requirements of information transmission, processing, storage, display,
recording and control.


The characteristics of sensors include miniaturization, digitization,
intellectualization, multifunction, systematization and networking. It is the
primary link to realize automatic detection and automatic control. The
existence and development of sensors make objects have senses such as touch,
taste and smell, and make objects slowly become alive. According to its basic
sensing function, it is usually divided into ten categories: thermal element,
photosensitive element, gas element, force element, magnetic element, humidity
element, sound element, radiation element, color element and taste element.

The characteristics of sensors include miniaturization, digitization,
intelligence, multi-function, systematization and networking. It not only
promotes the transformation and upgrading of traditional industries, but also
may establish new industries, so as to become a new economic growth point in
the 21st century. Miniaturization is based on micro electro mechanical system
(MEMS) technology. It has been successfully applied to silicon devices to make
silicon pressure sensors.
