PM2.5 refers to particles with a diameter of 2.5 microns or less in the atmosphere, or 2,500 nanometers. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution is.
There are many fine particles in the air that enter our body with our breath, but we can't see them with our naked eyes. A bright pathway is visible in the air, indicating that there are many particles in the air that we can't see entering our body through our respiratory tract all the time, and if the concentration of harmful particles is too high, it will have an impact on our health.
PM2.5 air pollution
Purely from the naked eye to observe, is very inaccurate, especially PM2.5 dust particles. Laser sensor is a sensor device using laser technology for measurement. The laser sensor can realize contactless measurement with large range, high precision, strong anti-interference ability and fast speed. The laser dust sensor USES the principle of laser scattering to convert the scattered signals of PM2.5 particles into photoelectric signals, and amplifies the electrical signals to display the collected dust concentration.
The laser air sensor developed and produced by luftmy, a manufacturer of particle concentration sensor, can be embedded with various instruments related to the concentration of suspended particulate matter in the air, such as air detector or environmental improvement equipment, to provide timely and accurate concentration data.
