Sensors have a wide range of applications in our daily lives. Long ago, logic components, memory components, and sensing components were already listed as the three major components of electronic systems. The development of pressure measurement, mechanical measurement, electrical measurement has undergone many changes, and now it is the era of sensors. So what is the principle of sensors? Which fields are they being applied to now? Let's take a look together below:

1. Working principle

Firstly, a ± 15V power supply is provided to the sensor, and the crystal oscillator in the excitation circuit generates a 400Hz square wave. After passing through the power amplifier, an AC excitation power supply is generated, which is transmitted from the stationary primary coil to the rotating secondary coil through an energy ring transformer. A high-precision regulated power supply consisting of a reference power supply and dual operational amplifiers generates a precise DC power supply of ± 4.5V. When the elastic shaft is twisted, the strain signal at the mV level detected by the strain bridge is amplified into a strong signal of 1.5v ± 1v through an instrument amplifier, and then converted into a frequency signal through a V/F converter. The signal is transmitted from the rotating primary coil to the stationary secondary coil through a signal ring transformer, and then filtered and shaped by a signal processing circuit on the housing to obtain a frequency signal proportional to the torque borne by the elastic shaft. It can be provided to dedicated secondary instruments or frequency meters for display or directly sent to a computer for processing.

Due to the gap of only a few tenths of millimeters between the dynamic and static rings of the rotary transformer, and the fact that the upper part of the sensor shaft is sealed inside a metal shell, effective shielding is formed, thus it has strong anti-interference ability.

2. Application Fields

2.1 Household appliances

Sensors are commonly used in modern household appliances. Sensors have been widely used in electronic stoves, automatic rice cookers, vacuum cleaners, air conditioners, electronic water heaters, hot air heaters, air dryers, alarms, electric fans, game consoles, electronic mosquito repellents, washing machines, dishwashers, cameras, refrigerators, color and flat screen televisions, video recorders, tape recorders, radios, DVD players, and home theaters.

2.2 Medical

With the development of medical electronics, the era of diagnosis based solely on doctors' experience and intuition will come to an end. Nowadays, the application of medical sensors can perform high difficulty diagnosis on the surface and internal temperature, blood pressure and intracavity pressure, blood and respiratory flow, tumors, blood analysis, pulse and heart sounds, heart and brain waves, etc. of the human body. Obviously, sensors play a very important role in promoting the high development of medical technology.

2.3 Military field

The current battlefield is an informationized battlefield, and informationization is absolutely inseparable from sensors. It can be said that it is used at all times and places, from equipment systems such as celestial bodies, two bombs, airplanes, ships, tanks, artillery, to individual combat from participating in logistics support; From military scientific experiments to military equipment engineering; From battlefield operations to strategic and tactical command; From war preparation, strategic decision-making to war implementation, it covers the entire combat system and the entire process of war, and will inevitably expand the time, space, and frequency domains of combat in future high-tech wars, greatly affecting and changing the way and efficiency of combat, greatly enhancing power, combat command, and battlefield management capabilities.

2.4 Environmental Protection

At present, the air pollution, water pollution, and noise on Earth have seriously disrupted the ecological balance and the environment we rely on for survival. This situation has attracted the attention of countries around the world. Various environmental monitoring instruments made from sensors are playing a positive role in protecting the environment.

The current environment in China has been greatly polluted, mainly due to the development of industry causing serious pollution. The Yangtze River, Yellow River and other water bodies have varying degrees of pollution; The air is not fresh now, especially in industrial areas where PM2.5 and other pollutants exceed the standard; These are all detected through sensors.

2.5 Internet of Things

The Internet of Things refers to the integration of ubiquitous end devices and facilities, including sensors with "intrinsic intelligence", mobile terminals, industrial systems, building control systems, home smart facilities, video surveillance systems, and "externally enabled" assets such as RFID labeled assets, individuals and vehicles carrying wireless terminals, and other "intelligent objects or animals" or "smart dust" (Mote), through various wireless/wired long-distance/short distance communication networks to achieve interconnectivity (M2M), application integration (Grand Integration), and cloud based SaaS Operation and other modes provide safe, controllable, and personalized real-time online monitoring, location tracing, alarm linkage, dispatch command, contingency plan management, remote control, security prevention, remote maintenance, online upgrading, statistical reporting, decision support, leadership desktop (centralized Cockpit Dashboard) and other management and service functions, realizing the integration of "management, control, and operation" of "efficiency, energy conservation, safety, and environmental protection" for "everything". Simply put, the Internet of Things is the transmission and control of information between objects, people, and objects. There are three key technologies in the application of the Internet of Things, including sensor technology.

2.6 Robots

At present, robots have gradually replaced human work in places with high labor intensity or hazardous operations. It is also very suitable for robots to undertake some high-speed and high-precision tasks. But most of these robots are used for processing, assembly, inspection and other work, and are used as automated mechanical single energy robots for production. Only sensors that detect the position and angle of the arms are used on these robots.

To make the functions of robots and humans more similar, in order to engage in more advanced work, robots are required to have judgment ability. This requires installing object detection sensors, especially visual and tactile sensors, on robots to recognize and detect objects through vision, and to generate pressure, force, sliding, and weight sensations through touch. This type of robot is called an intelligent robot, which can not only perform special tasks, but also handle general production, affairs, and household chores, all of which can be handled by intelligent robots. This is currently one of the main research objects for the development of robots
