With the rapid development of science and technology, sensors have become an indispensable part of modern life. Sensors can convert physical quantities into electrical signals, used in a variety of automation control system processing and feedback. Let us talk about the structure principle and application of various sensors.
Temperature Sensors
Temperature sensors are sensors that convert temperature into an electrical signal output. They usually use thermistors, thermocouples or infrared sensors and other technologies to achieve the measurement of temperature. Temperature sensors are widely used in industrial automation, medical equipment, household appliances and other fields, such as air conditioners, refrigerators, water heaters and so on.
Humidity Sensors
Humidity sensors are sensors that convert humidity into an electrical signal output. They usually use capacitive, resistive, electrochemical and other technologies to realize the measurement of humidity. Humidity sensors are widely used in meteorology, environmental monitoring, food processing and other fields, such as air purifiers and smart washing machines.
Pressure Sensors
Pressure sensors are sensors that convert pressure into an electrical signal output. They usually use strain gauges, piezoelectric crystals, capacitive and other technologies to realize the measurement of pressure. Pressure sensors are widely used in automotive manufacturing, medical equipment, aerospace and other fields, such as automotive tire pressure monitoring systems, blood pressure monitors and so on.
Optical Sensors
Optical sensors are sensors that utilize optical principles to make measurements. They usually use technologies such as lasers and photodiodes to realize optical measurements. Optical sensors are widely used in robotics, rangefinders, and photoelectric switches, such as self-driving cars and security systems.
Microwave Sensors
Microwave sensors are sensors that utilize microwave signals for measurement. They usually use radar, microwave antenna and other technologies to realize the measurement of microwave signals. Microwave sensors are widely used in the fields of radar ranging, vehicle control, and human body detection, such as intelligent parking lots and intelligent lighting systems.
In short, there are many kinds of sensors with a wide range of applications. With the continuous progress of science and technology, the performance of sensors is also improving, will bring people a more convenient and intelligent life.
