With the introduction of PM2.5, people have become increasingly concerned about environmental issues in their surroundings. PM2.5 refers to particulate matter with an aerodynamic equivalent diameter of 2.5μm or less in the ambient air, also known as fine particulate matter. The higher this value, the more serious the air pollution. The haze weather we often see in the news or around us is caused by suspended fine particles of PM2.5.

A handheld air quality detector can help us check the air quality of our surroundings, displaying the PM2.5 concentration value, temperature, humidity, etc. Handheld air quality detectors can be used in buildings, workshops, and other fields. Luftmy provides gas sensor solutions applied to air quality detectors, including laser PM2.5 dust sensors and infrared PM2.5 dust sensors.

For measuring PM2.5 on an air quality detector, we choose Luftmy's PM2.5 sensor LD16. The PM2.5 dust laser sensor module LD16 is a high-precision particulate matter concentration sensor developed and produced using Mie scattering theory. It continuously collects the concentration distribution of particles with different diameters in the air and outputs it as a universal digital interface. This laser sensor can be embedded in various air purifiers, smoke alarms, fresh air systems, air detectors, and other instruments or environmental improvement equipment related to suspended particle concentration, providing timely and accurate concentration data.

The infrared PM2.5 sensor module GDS06 is also suitable for measuring PM2.5 on air quality detectors. It uses the principle of optical scattering to measure the dust concentration within the detection range through optical and circuit conversion. It features small size, high precision, low power consumption, and short response time. This PM2.5 dust infrared sensor module is used in air conditioners with purification functions, air purifiers, vehicle-mounted purification equipment, portable detectors, fresh air systems, smart detectors, air quality detectors, etc.
