Ambient and laboratory evaluation of a lowcost ...

01/02/2017· There are a few potential reasons for the PMS''s better response than the Shinyei in ambient studies: flow control into the sensor, the sensor light source, and intrinsic limitations in the comparison of gravimetric and optical estimates of PM concentration. The PMS employs a fan to draw air past the sensor, whereas the Shinyei uses resistive heating to induce convective flow past the …


Grove Dust Sensor

Here is a demo to show how to obtain PM concentration data from this Grove Dust Sensor. 1. Plug the dust sensor into digital port D8 on the Grove Base Shield. It can only be D8 because the operation of this sensor involves sampling. This function only can be achieved by D8, the input capturing pin of ATmega328P, on Arduino/Seeeduino.

Particle Sensor Unit | SHINYEI Technology

Particle Sensor Unit PPD20V. Based on the light scattering method, it detects particles over µm (approx). An analog voltage signal that corresponds to concentration per unit volume of particles can be obtained, with using an original detection method based on light scattered principle similar to the particle counter.
