Sensors can measure and sense various physical quantities in the environment, such as temperature, humidity, pressure, light intensity, sound, etc., and convert them into electrical signals for digital processing and analysis. It is also necessary to pay attention to maintenance during use to ensure its normal operation and long-term stability. This article will introduce the application scenarios and common types of sensors, and provide some maintenance guidelines to help readers better understand and use sensors.
1. Sensors and environmental protection.
At present, the earth's air pollution, water pollution and noise have seriously damaged the earth's ecological balance and the environment on which we live, and this situation has attracted the attention of all countries in the world. In order to protect the environment, various environmental monitoring instruments made of sensors are playing an active role.
2. The application of sensors in robots.
In places where labor is intensive or dangerous, robots have been gradually used to replace human work. Some high-speed, high-precision work is also very suitable for robots to undertake. However, most of these robots are automatic mechanical single-energy robots used for processing, assembly, inspection, etc. Only sensors that detect the position and angle of the arms are used in these robots.
3. Sensors and household appliances.
Sensors are ubiquitous in modern home appliances. Sensors are widely used in household appliances such as electronic stoves, automatic rice cookers, vacuum cleaners, air conditioners, and electronic water heaters.
4. Sensors and Internet of Things.
The Internet of Things is a network based on the Internet, traditional telecommunications networks and other information carriers, so that all ordinary physical objects that can be addressed independently can be interconnected. It has three important characteristics: the deviceization of ordinary objects, the interconnection of autonomous terminals, and the intelligence of ubiquitous services.
5. The application of sensors in medical treatment and human medicine.
With the development of medical electronics, the era of diagnosis based solely on the experience and feeling of doctors will come to an end. Nowadays, medical sensors can be used to diagnose the surface and internal temperature, blood pressure and intracavity pressure, blood and respiratory flow, tumors, blood analysis, pulse waves, heart sounds, and heart and brain waves. Obviously, sensors play a very important role in promoting the high development of medical technology.
6. Sensors and remote sensing technology.
Satellite remote sensing is an integral part of aerospace remote sensing, which uses artificial earth satellites as remote sensing platforms, mainly using satellites to conduct optical and electronic observations of the earth and the lower atmosphere. That is, from different working platforms far from the ground (such as towers, balloons, airplanes, fire bars, artificial earth satellites, spacecraft, space shuttles, etc.) through sensors, the electromagnetic wave (radiation) information on the earth's surface is detected, and through the transmission, processing and interpretation of the information, the earth's resources and environment are detected and monitored.
How to care for the sensor.
1. It is necessary to prevent the sensor from contacting corrosive gases, so as not to cause corrosion and affect the measurement results.
2. If the measurement is a high-temperature medium, it is necessary to see whether the temperature is within the appropriate temperature range of the sensor, if not, you cannot use this equipment to measure, you need to choose a suitable sensor to measure, but at the same time, it is also necessary to pay attention to the measurement, do not have sediment sedimentation.
3. The impulse pipe should be installed in an area with a small temperature change, and should not be installed in a place with large temperature fluctuations, so as not to damage the force equipment.
4. When measuring liquid, it is necessary to prevent the direct impact of the liquid on the sensor, because the direct impact of the liquid may cause damage to the sensor, which will affect the accuracy of the measurement results, and may also make it unable to work normally.
5. When measuring gas, the sensor should be installed in the upper part of the process pipeline, and the pressure port should also be opened at the top of the process pipeline, so that the accumulated liquid can flow into the process pipeline.
6. When wiring, use a waterproof connector and tighten the nut to avoid rainwater from seeping into the shell of the transmitter.
7. If the weather is cold in winter, the temperature is relatively low, or even when freezing, when the sensor is installed outdoors, anti-freezing and warmth measures must be taken to prevent the liquid in the impulse port from increasing and expanding in volume due to icing and destroying the sensor.
The above is an introduction to the application and maintenance guide of the sensor. IC Shopping is committed to continuously promoting and publicizing new technologies and products to help users understand and choose the most suitable components for their needs.
