1PC PMS5003 G5 High Precision Laser Dust Sensor Module PM1.0 PM2.5 PM10

MS5003 particle concentration (G5) is a universal digital sensors, per unit volume can be used to obtain the quality and quantity of suspended particles in the air, and the output in the form of digital interface. The sensors can be embedded in a variety of instruments associated with concentration of suspended particles in the air or environment to improve the equipment, the concentration of providing timely and accurate data.  

The sensor adopts laser scattering theory. Present laser scattering produces on the suspended particles in the air, at the same time at a specific Angle collect the scattered light, the curve of the scattering intensity changes over time. Then the microprocessor using the algorithm, based on the theory of the MIE (MIE) concluded that grain content of equivalent grain size of different size particles per unit volume and quantity.
