What sensors are used for indoor air quality monitoring?

Everyone lives in a closed or semi-closed environment for most of the day, so indoor air quality is particularly important.However, the rapid development of urbanization has led to air pollution in many cities, and indoor air quality is also bad, which directly affects people's health and life quality.In order to improve indoor air quality, many indoor places and families now have installed air purifier and other environmental monitoring equipment.

What sensors are used for indoor air quality monitoring

Generally speaking, indoor environment monitoring should include the monitoring of carbon dioxide, temperature, humidity, PM2.5 particulate matter, noise, formaldehyde, air pressure and so on.So, which sensors are used in indoor air quality monitoring?

If a lot of people gather indoors, and the air is not circulating, the oxygen content in the air will be relatively reduced, producing a large number of carbon dioxide, indoor staff will appear different degrees of poisoning symptoms.The co2 sensor transmits the measured CO2 concentration to the air quality detector via digital or analog signals.

In order to ensure indoor air environment, we can use formaldehyde sensor to monitor indoor formaldehyde content.The formaldehyde sensor is composed of shell, probe and output line.Indoor air is sucked into the transmitter by the probe, monitored by the sensor inside and calculated the formaldehyde concentration.

According to the requirements of national indoor air quality standards: indoor air humidity standard in winter is 30% ~ 60%, humidity index is 50% ~ 60% of the most comfortable environment, indoor temperature is not higher than 24 degrees.Therefore, temperature and humidity sensors should be used for monitoring.

In the current field of air purification, PM2.5 sensor has almost become the standard component of air purification equipment, whose function is to monitor the concentration of PM2.5 and other particulate matter in the air.

Applied to air purification equipment of PM2.5 sensor type LUFTMY exceed recommended laser LD09 dust sensor modules, it adopts the Mie spherical particle scattering principle to accurate measurement of concentration of particulate matter in the environment, the dust sensor module design light, small volume, suitable for air purification machine, fresh air system and air quality monitoring equipment.
