Dust Sensor () | MySensors Forum

Aug 17, 2014· I would like to notice that this setup of sharp dust sensor outputs highly unreliable measurements. Yes, this is hy I asked for a moratory on the shop and went out to try other versions which are cheaper (the DSM501 and the Shinyei PPD42NS) . I received a dead Shinyei PPD42NS, and am still in escalation on aliexpress on that.

Laboratory Evaluation of the Shinyei PPD42NS Low-Cost ...

Sep 14, 2015· Objective Finely resolved exposure measurements at the level of individual participants or over a targeted geographic area can be challenging due to the cost, size and weight of the monitoring equipment. We propose re-purposing the low-cost, portable and lightweight Shinyei PPD42NS particle counter as a particle counting device. Previous field deployment of this sensor suggests that it ...

This is based on Shinyei PPD42NS Dust Sensor. The Particulate Matter level (PM level) in air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration. The sensor responds to PM of diameter 1 ¦Ìm or larger. This sensor can provide reliable data for air purifier systems.??Key

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.
