In order to get information from the outside world, people must resort to sensory organs.However, it is far from enough to rely on people's own sensory organs in the study of natural phenomena and laws as well as production activities.To accommodate this, sensors are needed.Therefore, it can be said that the sensor is an extension of the human five senses, also known as the electrical five senses.With the rapid development of the information age, sensors have been widely used in life and production applications. The following is the application of sensor modules such as PM2.5 sensor in daily life.
The harmful gas detection after the new house decoration
The harmful gas of 90% above in newly decorated room exceeds bid seriously, take formaldehyde as an example.Many new homes are newly renovated and have formaldehyde concentrations in excess of 2.5 parts per million, some as high as 10 parts per million.At this point, a variety of gas sensors, sensors, volatile organic compounds such as formaldehyde sensor, air quality sensor, etc., are applied to family life environment, such as formaldehyde, benzene, toluene and volatile organic compounds (VOCs) add independent gas detection products, or integrate the gas sensor with air conditioner, air purifier, in order to achieve the purpose of combining the new residential pollution detection and processing, to create a comfortable home environment.
New car in-car air quality monitoring
According to the investigation, 93.6% of the new car indoor air pollution seriously exceeds the standard, the pollution source in the car mainly comes from the decoration material of the car body itself, among which formaldehyde, xylene, benzene and other toxic material pollution consequence is the most serious, may cause cancer.Another often reported harmful gas in cars is carbon monoxide, known as the "silent killer."Its main source is automobile engine and automobile exhaust, which is produced by turning on air conditioning when parking.If people stay in cars for a long time, people in cars can unconsciously inhale the colorless, odorless and toxic gas and become poisoned.The use of appropriate gas sensors, such as formaldehyde sensors, carbon monoxide sensors and PM2.5 sensors, can not only monitor volatile organic compounds such as formaldehyde and benzene.It can also monitor the concentration of carbon monoxide in the car, so as to play the role of safety warning, remind the owner to take effective improvement measures to prevent the tragedy.
PM2.5 dust detection in indoor air
Indoor pm2.5 mainly comes from smoke during smoking and lampblack produced during cooking in the kitchen.These particles are vulnerable to various diseases, especially for the elderly, children, infants or people with respiratory diseases.Therefore, PM2.5 dust sensors are widely used in air purifiers, fresh air systems and air quality monitors. For example, the LD09 laser PM2.5 sensor module of LUFTMY is very small in size, which is usually used to detect indoor dust concentration in real time in air purifiers and other devices, and remind air purifiers to work by displaying the value.
