25/01/2017· Shinyei PPD42NS. from the data sheet: This sensor is to create Digital (Lo Pulse) output to Particulate Matters(PM). Lo Pulse Occupancy time (LPO time) is in proportion to PM concentration. The output from “P1” is for PM whose size is around 1 micro meter or larger. Model PPD 42NS; Detectable particle size: approx. 1 μm (minimum.) Detectable range of concentration: 028,000 pcs/liter (08 ...

They used either the Sharp GP2Y1010AU0F or the Shinyei PPD42NS. These sensors generally operate based on the lightscattering principle, by measuring the amount of light that is scattered by particles. The PPD42NS. Chris Nafis has done a great job documenting the use of both the GP2Y1010AU0F and the PPD42NS, compared against a Dylos DC1100 air quality monitor. As the GP2Y1010AU0F requires a ...

Two dust sensors PPD42NS Shinyei were integrated with an Arduino Due board and a HUZZAH ESP8266 wi module that sends data to the cloud and saves it for further analysis. Each sensor provided two outputs that were indicative of the concentration of particles larger than 1 mor 2:5 m. The sensors were placed in a home terrace during several weeks. The acquisition system proved 3 (a) Acquired ...

What does the Shinyei PPD42NS LowCost Dust Sensor Really ...

+

Shinyei PPD42NS sensor seems very popular due to its very low cost ( 8 15 USD) and apparent ease of use. Note that the Shinyei PPD42NS, Syhitech DSM501A and Samyoung DSM501 sensors are identical and produce the same PWMlike output (Pulse Width Modulation signal with variable frequency and duty cycle). Therefore, this analysis also applies to these three sensors. B. Electronic Description ...

Particle Sensor Unit PPD42NJ Based on the light scattering method, it detects airborne particles continuously. Pulse output 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.
