This diagram shows types, and size distribution in micrometres, of atmospheric particulate matter This animation shows aerosol optical thickness of emitted and transported key tropospheric aerosols from 17 August 2006 to 10 April 2007, from a 10 km resolution GEOS-5 "nature run" using the GOCART model.[1][2] (click for more detail) * green: black and organic carbon * red/orange: dust * white: sulfates * blue: sea salt Movie map of distribution of aerosol particles, based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite. * Green areas show aerosol plumes dominated by larger particles. * Red areas show aerosol plumes dominated by small particles. * Yellow areas show where large and small aerosol particles are mixing. * Gray shows where the sensor did not collect data. Atmospheric particulate matter – also known as particulate matter (PM) or particulates – is microscopic solid or liquid matter suspended in the Earth's atmosphere.

Standalone: Sharp Dust Sensor ← Arduino Tutorials We based our work on the excellent post over here but contrary to the author, we did not try out multiple sensors and we are using an Arduino Fio. In this tutorial, we’ll focus on how to get your Sharp Optical Dust Sensor to work and what to watch out for. In addition, we will try to provide European shop references and prices in € where possible.

Particules en suspension Un article de Wikipédia, l'encyclopédie libre. Pour les articles homonymes, voir PM. Les particules en suspension sont d'une manière générale les fines particules solides portées par l'eau ou solides ou liquides portées par l'air. On peut les recueillir et quantifier par filtration ou par d'autres procédés physiques. Les matières particulaires (PM, (en) Particulate Matter) désignent les particules en suspension dans l'atmosphère terrestre[1]. Les matières particulaires dans leur ensemble sont désormais classées cancérigènes pour l'homme (Groupe 1) par le Centre international de recherche sur le cancer (CIRC)[2].

Sharp Dust Sensor and Arduino Sharp’s GP2Y1010AU0F is an optical air quality sensor, designed to sense dust particles. An infrared emitting diode and a phototransistor are diagonally arranged into this device, to allow it to detect the reflected light of dust in air. It is especially effective in detecting very fine particles like cigarette smoke, and is commonly used in air purifier systems. The sensor has a very low current consumption (20mA max, 11mA typical), and can be powered with up to 7VDC. The output of the sensor is an analog voltage proportional to the measured dust density, with a sensitivity of 0.5V/0.1mg/m3. This is how the optical dust sensor works: Build a Rocket Stove for Home Heating Author’s note, 2015-02-14: Based on the interest I’ve received in this project, I’m considering selling plans for a stove similar to the one described in this article. See the Rocket Stove Plans section at the end of the article and let me know if you’d be interested. Original article: For some time I’ve been considering the best way to deal with a pile of scrap wood that has been growing next to my home, the result of many woodworking and carpentry projects I’ve been involved in over the years.

The Mental Munition Factory: Measure air pollution in your home or backyard with a DustDuino This week, the World Health Organization (WHO) took a major step by announcing that air pollution is carcinogenic to humans. WHO also announced they are considering particulate matter, a major component of indoor and outdoor air pollution, as carcinogenic to humans as well. The International Agency for Research on Cancer (IARC), a special unit inside WHO tasked with promoting international collaborations on cancer research, reached that conclusion after reviewing more than 1000 scientific papers on the carcinogenicity of air pollutants. Air pollution and particulate matter will be included in IARC's Monograph, which is an encyclopedia of known carcinogens. Particulate matter will be classified as a Group 1 carcinogen, along with tobacco smoke and asbestos. In an IARC press release [1], the Deputy Head of the Monographs Programme, Dr.

Le poêle à bois : danger ou alternative ? Alliant véritable confort de chauffe selon l’isolation de la maison et besoins de chauffage, le poêle à bois est particulièrement simple à installer, puisqu’il suffit qu’il soit raccordé à un conduit d’évacuation. Offrant des performances de chauffe exceptionnelles qui permettent d’élever la température d’une pièce en très peu de temps, jouissant d’une installation facile et modifiable, le poêle à bois reste-t-il un bon moyen de passer l’hiver au chaud ? Le rendement d’un poêle à bois est de 60 % à 80 %, en moyenne par rapport aux cheminées à foyer ouvert, dont le rendement ne dépasse pas 20 %. Dust Sensor [中文] Introduction This Dust Sensor measures the Particulate Matter level in air by counting the Lo Pulse Occupancy time(LPO time) in given time unit. LPO time is in proportion to PM concentration. This sensor can provide you pretty reliable data for your PM2.5 project or air purifier system because it's still responsive to particulates whose diameter is 1um.

La pollution atmosphérique comparée 2. Revisions for 'DustDuino' What is it? DustDuino can help individuals with limited resources monitor PM10 and PM2.5 concentrations, indoors or outdoors. It uses Shinyei PPD42NS, a $15USD optical sensor that uses an LED and a lens to determine the concentration of dust in a partially closed chamber that draws in air from its surroundings. The sensor data is received by an Arduino development board and transmitted to Xively. Prototypes of DustDuino have been successfully built and used in various indoor and outdoor locations.

(rocket mass heater forum at permies) I was looking for scientific publications on anything closely relating a rocket mass heater just the other day. The closest thing I could find were journal publications on particulate emissions for masonry heaters. The studies were typically performed in Europe. When I lived in Germany my friend told me they were quite concerned about combustion particulates (diesel trucks and wood burning, typically). How I found the articles (abstract only typically): did a search on 'masonry heaters'
