Infrared dust sensor can be installed in PM2.5 detector. However, if it is a portable PM2.5 detector, because it requires fast response and the test field may be in change, laser PM2.5 sensor is generally used, while some fixed PM2.5 detector or PM2.5 detector that does not need to be moved frequently can be installed with infrared PM2.5 sensor.

No matter the infrared dust sensor or the laser dust sensor, if there is no special environmental demand, they can accurately measure the concentration of particles in the air.The difference is that the laser dust sensor with a fan can produce a stable airflow, as long as the start-up, it can quickly obtain the PM2.5 concentration value of the current environment.In the infrared dust sensor, there is only a heating resistance but no fan. After the resistance is heated up, the temperature difference between the inside and outside of the sensor can generate air flow, and detect the PM2.5 concentration in the air flow.Because of this reason, infrared dust sensor is not suitable for portable detector.
Portable PM2.5 detector structure
Although infrared dust sensor has no fan to bring stable airflow, it also has the irreplaceable advantage of laser dust sensor, that is, low price, suitable for more products.
