Have a look at our Air Quality Monitoring overview page!
Also take a gander at these Air Quality Monitoring Systems we made with SC – AQMD (Southern California Air Quality Management District).
AQMD is a California government entity. SC-AQMD is responsible for air quality monitoring and compliance in Los Angeles, Orange County, and the great majority of Southern California.
This write-up shows how your organization can use sensor hubs, industrial sensors like Alphasense air quality sensors, and the Tools.Valarm.net gateway. This lets your organization rapidly deploy boxes to remotely monitor just about any air quality factor, like:
- Particulate Matter – PM1, PM2.5, PM10 with Optical Particle Counters like the Alphasense OPC-N2
- Specific Gases – O3 (Ozone), NO2 (Nitrogen Dioxide), H2S (Hydrogen Sulfide), VOCs (Volatile Organic Compounds)
Quality of life and air quality are important for citizens all around the world, but how do you know what your environment is really like?
The air we breathe every day has volatile organic compounds (VOCs) such as methane (from human breath), alcohol (cleaning supplies), formaldehyde (materials for building), ketones (paints), esters (glues), and terpenes (perfume). These are harmful to human health so:
- How can we find out how much bad air we’re breathing?
- Are there areas that are better for us to be when we’re outside?
- If you had the choice of where to go for an outdoor activity, would you choose based on air quality?
I was curious about this so I conducted a study in the Los Angeles, California, area using Tools.Valarm.net.
Valarm compatible sensors are available at Shop.Valarm.net. You can follow these steps and do the same thing in your neighborhood or area of interest to know your outdoor and indoor air quality (IAQ).
For some people the Los Angeles area is notorious for pollution, but LA covers a lot of area so which parts of town are more dangerous for your health?
Air quality can be observed to vary dramatically from the west end of the city (where the ocean is) to the east end, where mountains seem to trap pollutants. There’s also variability from the north to south in air quality (and other health factors).
My curiosity about this led to a presentation at the Vespucci Institutes: Synthesizing Population, Health, and Place on Catalina island. The pink dots in the map below show the areas where I collected Valarm VOC data.
Some residential neighborhoods like El Segundo, California, are surrounded by chemical emitters such as refineries, airports, busy roads and freeways, and sewage treatment plants. Below are a couple pictures of the city of El Segundo taken on a Valarm data collection trip.
To do personal environmental monitoring with Valarm I plugged in the Yocto VOC sensor and then placed the sensor in my jacket before I ran and walked around the different neighborhoods.
I used Valarm’s interval timer to collect data about the environment every 15 seconds. Next the Valarm data was uploaded to the Valarm Tools website where I could see the mobile data acquisition points and view graphs of sensor data.
Then I downloaded the VOC and air quality data in KML format from Valarm Tools in order to see it in 3D with Google Earth. [Tutorial here: How To Import Valarm Data Into Google Earth]
Now I can see the volatile organic compounds (VOCs) and their various ppm levels on a 3D globe.
And you can do spatial interpolation with GIS analysis methods like inverse distance weighting (IDW) and kriging to create pollution maps.
The air quality study shows parts of the Los Angeles, California, area that are potentially more dangerous, your results may vary!
As a result of all this I’ll do my running and outdoor exercise in the western part of Los Angeles. This opens up the possibility for crowdsourced air quality measures since anyone can download and share their Valarm data as much as they like. Where in the world are the most dangerous levels of air quality?
You, your teams, and your organization can effectively monitor remote assets with Tools.Valarm.net. Our customers do things like water resources management, environmental monitoring, and chemical resources management, fluid monitoring.
