Smart home sensor home appliance machine industry application advantages microwave remote sensing equipment features and functions

Smart home sensors, home appliances and machinery industry application advantages Microwave remote sensing equipment features and functions, a sensor is a detection device that converts the measured sensory information into electrical signals or other necessary forms of information output according to certain rules. Meet the requirements of information transmission, processing, storage, display, recording and control. Sensors are actually functional blocks that convert various signals from the outside world into electrical signals. In order to detect and control various signals, the signal must be received as simple and easy to process as possible. These requirements can only be met by electrical signals. Electrical signals can be easily amplified, stored, remotely manipulated, etc. So which industries can smart sensors be used in, and what are the advantages?

1. Environmental protection

Currently, air pollution around the world. Water pollution and noise have severely disrupted the ecological balance of the planet and the environment on which we depend. In order to protect the environment, various environmental monitoring instruments made with sensors have played an active role. Carbon monoxide, sulfur dioxide, formaldehyde, PM2.5 and other toxic and harmful gases in the air.

2, car sensor

At present, the application of automotive sensors is to measure related parameters such as fuel balance. Not just limited to driving speed. driving distance. Engine speed, due to the increase in automobile traffic accidents and the damage to the environment by automobiles, sensors are also used in some new facilities.

3. Appliances

Sensors are widely used in smart home appliances. Including induction cooker, automatic rice cooker, air conditioner, electronic water heater, alarm, refrigerator and other household products.

With the improvement of people's living standards, the requirements for improving the function and automation level of household appliances are very strong. In order to meet these requirements, first use high-precision sensors to detect analog quantities to obtain accurate control information, and then use microcomputer control to make household appliances more convenient. Safe and stable, reduce energy consumption, and create a comfortable living environment for more families.

4. Robots

At present, robots have gradually been used to replace human work in labor-intensive or dangerous workshops. These robots only use sensors to sense the position and angle of the arm. Make robots closer to human functions, do better work, and make robots have judgment. This requires the installation of medical sensors, especially vision and tactile sensors, on the robot so that the robot can recognize and perceive objects using vision. Feel the pressure of the object by touching it. Slip and feel of weight. Not only can it do special jobs, but general household chores can also be handled by smart robots.

5. Application of medicine and human medicine

With the development of medical electronics, the era of diagnosis based on the doctor's experience and feeling alone will come to an end. At present, the application of medical sensors can make difficult diagnosis of human body surface and internal temperature, blood pressure and lumen pressure, blood and respiratory flow, tumor, blood analysis, pulse wave heart sound, heart wave, etc. Obviously, sensors play a very important role in facilitating the high development of technology.

6. Civil

In terms of civil use, the application of gas sensors is mainly reflected in the detection of dangerous gas leaks such as natural gas, liquefied petroleum gas, and city gas in the kitchen, and automatic control of microwave ovens for cooking food. In some high-rise buildings, gas sensors can also be used to detect signs of fire and alarm.

In today's fast-developing era, sensors can be integrated into every corner of life to analyze users' daily behavior and increase the user's mode of interaction with the world around them. Smart sensors can greatly improve the convenience and safety of life.

What are the characteristics of microwave remote sensing equipment? Remote sensing technology includes sensor technology, information transmission technology, information processing, extraction and application technology, target information characteristic analysis and measurement technology, etc. According to the selected spectral characteristics of the remote sensor, remote sensing technology can be divided into electromagnetic wave remote sensing technology, sonar remote sensing technology, and physical field remote sensing technology.

Electromagnetic wave remote sensing technology is to use various substances to reflect or emit electromagnetic waves with different characteristics for remote sensing. It can be divided into visible light, infrared, microwave and other remote sensing technologies. According to the energy function of the sensing target, it can be divided into active remote sensing technology and passive remote sensing technology. According to the expression of recorded information, it can be divided into image mode and non-image mode. The remote sensor platform can be divided into space remote sensing technology, aerial remote sensing technology and ground remote sensing technology. According to the application fields of remote sensors, it can be divided into earth resources remote sensing technology, environmental remote sensing technology, meteorological remote sensing technology, ocean remote sensing technology, etc.

A microwave remote sensor uses a certain sensor to receive microwave signals emitted or reflected on the ground in various shapes, that is, the information needed to identify, analyze and extract pictures. Microwave remote sensors are divided into active and passive types. Active types include imaging radar. Microwave Diffuser Microwave Altimeter and Rain Radar. Passive types mainly include microwave radiometers. These microwave remote sensors have their own characteristics and applications.

Microwave remote sensors are immune to clouds, rain, and fog, require no lighting conditions, and can acquire images and data throughout the day. In addition, microwaves also have a certain permeability, so deeper information can be obtained. Microwave remote sensing: The remote sensing technology of the working wavelength of the sensor in the microwave spectrum uses a certain sensor to receive and identify the microwave signals emitted or reflected by various geographical shapes. Analyze the picture and extract the information needed for the picture. Microwave remote sensing is a new generation of advanced cosmic remote sensing technology developed at the end of the 21st century.

Various objects on the earth will reflect external microwave signals, and the objects themselves also have the ability to radiate microwaves. Microwave remote sensing refers to the detection of microwave reflections of object shape and structure or its own microwave radiation. Due to the strong microwave permeability, it is not limited by changes in weather conditions such as all-weather, all-day features, clouds, fog, or day and night lighting conditions. These characteristics make up for the shortcomings of optical remote sensors and become the new favorite of remote sensors.

According to the working principle, microwave remote sensing equipment can be mainly divided into two categories. One is an active remote sensing device, that is, a sensing device, which can actively emit microwave signals, and then receive reflected or scattered signals from the detected objects. It works similarly to the well-known radar. The other is a manual remote sensing device, similar to a spectrum sensing device. That is to say, high-sensitivity microwave receiving technology is used to receive the microwave radiation signal of the target itself.

The research and development of microwave remote sensing equipment has promoted the progress of science and technology and promoted the change of life. Remote sensing products are gradually popularized in daily life, bringing convenience to people's work and life.
