Laser Dust Sensor Module

 

1. Product description:
  MD202 laser dust sensor is a general digital particle concentration sensor, which can be used to obtain the number and
mass of suspended particles in the air per unit volume, that is the particleconcentration (μg/m³), and output it in the form
of digital interface.
  The sensor can be embedded in various instruments and apparatuses or environmental improvement equipment related
to the concentration of suspended particulate matter in the air to provide timely and accurate concentration data.
The sensor adopts the principle of laser scattering, that is to say, laser irradiation scatters on suspended particulate matter in the air.
  At the same time, scattered light is collected at a specific angle to obtain the curve of scattered light intensity changing with time.
Then the microprocessor uses the algorithm based on Michaelis(MIE)theory to obtain the equivalent particle size of particulate matter
and the number of particulate matter with different particle sizes per unit volume.

2. The characteristic of sensor:
(1). Comprehensive shielded design, strong anti-interference ability, both the inlet and outlet are set at the same side.
 Customer do not require operation for air duct;
(2). The minimum size of resolvable particle is 0.3μm;
(3). Ultra-thin material and super silent;
(4). Zero false alarm;
(5). Real-time response;
(6). Accurate data;
(7). Long life;

3. Main application:
(1). Air Quality monitors, portable instrument, air cleaner;
(2). Fresh air ventilator, air conditioning, equipment for smart home;
(3). Hospital, hotel and school and locus public;
