Air pollution, industrial pollution and other environmental problems are becoming increasingly serious. In recent years, haze weather also frequently appears, which leads to air quality problems that seriously affect people's living experien...
PM2.5 Sensor Module HPD05 use principle of optical scattering to measure concentration of dust inthe air,the module built in a Infrared Transmitter and a high sensitive Photoelectric Receiving Sensor the Infrared Transmitter emits light and ...
PM2.5 detector is specific to measure the PM2.5 (which can go directly to the alveoli of the lungs) data in the air. Laser method and particle counting...
pm2.5 laser sensor module LD09 adopts MIE spherical particle scattering principle, laser sensor uses laser to irradiate suspended particulate matter in the air to produce light scattering, photoelectric detector collects scattering light int...
The sensitivity of the dust sensor has a great influence on the performance of the smoke alarm, which determines the timeliness of the smoke alarm when it encounters the situation. However, once the fire alarm fails to alarm in time, the smo...
The principle of air purification can be seen as three steps: discovery, purification and release. Air purifiers detect indoor pollutants, filter them, and then expel clean air. Only when these three steps are well coordinated can air purifi...
Heart disease, lung disease, stroke and increased mortality have been clearly linked to air quality, particularly particulate matter concentrations (PM 2.5) and other standard pollutants....
PM2.5 sensor, also known as dust sensor, it can sense the environment within the scope of the dirt, dust, pollen, such as fine particulate matter, these tiny particles suspended in the air for a long time easy to cause air pollution, and som...
Vacuum cleaner has become an indispensable household cleaning tool for more and more families. How to distinguish the performance and function of vacuum cleaner?...
PM2.5 refers to fine particles with aerodynamic equivalent diameter less than or equal to 2.5 microns in ambient air.This kind of fine particulate matter mainly comes from the soot emission in industrial production, automobile exhaust in dai...
The detailed working principle of the dust particle counter sensor: the light from the light source is focused into the measuring cavity by the lens. When every particle in the air passes through the measuring cavity quickly, the incident li...
