This is a multifunction air quality monitor that can detect not only the concentration of particles but also the value of temperature and humidity.

As the particle concentration sensor it can be used to obtain the number of suspended particles in the air by laser, as well as temperature and humidity.

The sensor can be inserted into variable instruments related to the environment parameters in the air or other environmental improvement equipments to provide correct data in time.

Working principle: Laser scattering principle is used for such sensor, i.e. produce scattering by using laser to radiate suspending particles in the air, then collect scattering light in a certain degree, and finally obtain the curve of scattering light change with time. In the end, equivalent particle diameter and the number of particles with different diameter per unit volume can be calculated by microprocessor based on MIE theory.

Features

Zero false alarm rate
Real-time response
Correct data
Minimum distinguishable particle diameter :0.3 micrometer
High anti-interference performance because of the patent structure of six sides shielding
Optional direction of air inlet and outlet in order to adapt the different design
Temperature and Humidity output
