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 responsible for air quality monitoring and compliance in Los Angeles, Orange County, and the grand majority of Southern California.

This write-up shows how your organization can use sensor hubs, industrial sensors like Alphasense air quality sensors, and Tools.Valarm.net – to 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)



Sustainable DC LogoValarm is working with the City of Washington, D.C., to provide public maps with real-time air quality! We’re part of the Sustainable DC Plan to make DC the healthiest, greenest, most livable city in the nation over the next 20 years. Here’s specific goals / targets:

  • Minimize the generation of greenhouse gas emissions from all sources.
  • Reduce greenhouse gas emissions by 50%.
  • Advance physical adaptation and human preparedness to increase the District’s resilience to futureclimate change.
  • Require all new building and major infrastructure projects to undergo climate change impactassessment as part of the regulatory planning process.

In order to measure, understand, and report progress toward sustainability goals, D.C. requires a measurement and monitoring solution that will provide real world, comprehensive, historical data about climate change and air quality. That’s where Valarm sensor and monitoring solutions come in! Here’s how we’re doing it:

  1. Placing mobile Valarm units on the rooftops of city-owned vehicles
  2. Valarm units gather geotagged air quality sensor data
  3. Monitoring units send air quality data to the Valarm Tools Cloud in real-time
  4. Valarm APIs allow for customized endpoints, webpages, and business intelligence systems to analyze and visualize real-time air quality data

We recently did pilot studies for this by deploying air quality sensors on public transit in California and on pedestrian / citizen sensors. With your neighborhood’s air quality information and the Esri ArcGIS platform you can know what your current situation is and decide if you want walk, bike, drive, or take public transit based on your health conditions. See the video below for an example of Valarm air quality sensor data visualized with Esri 3D tools.


Here’s a list of environmental factors Valarm will be collecting:

  • Presence and concentration of Volatile Organic Compounds as a group (VOCs)
  • Temperature
  • Humidity
  • Barometric Pressure
  • CO2 concentration
  • Particulate matter (PM2.5, PM10, “soot”)

Having this real-time, mobile air quality data available to citizens means it will be of use to the public and have wide ranging impacts for:

  • K-12 science/social programs
  • University researchers
  • Government researchers
  • Gaining a better understanding of the environmental impact of street-level design/policy decisions

We’ll be posting more updates this spring and summer on the deployment along with the webpages and maps where you can get the air quality info. Please don’t hesitate to contact us if you have any questions!
