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)



Valarm Deploying Real Time Mobile Geotagged Sensor Air Quality DC - 2

Sustainable DC LogoGovernment vehicles around the world drive every day throughout their areas – do you feel they could be collecting environmental sensor data at the same time? We sure do! That’s exactly what we did working together with the government of City of Washington, D.C., and OCTO.

The City of Washington, D.C., now uses Valarm sensor solutions to remotely monitor mobile sensors in real-time! Lorenzo & Edward recently deployed Valarm units on D.C. government vehicles to monitor environmental factors like air quality, temperature, humidity, pressure. These vehicles, driven by IT staff, are regularly driving around the city so they might as well be gathering useful ambient sensor information!

All of the geo-tagged sensor data is sent in real-time to the Valarm Tools Cloud via the Verizon cell network – huge thanks to Verizon for their support on this! Once the sensor information is in the cloud it can be mapped, graphed, analyzed, downloaded, or forwarded in real-time via Valarm Tools Cloud APIs for JSON, CSV, KML, and GeoRSS.

In the photos you’ll see a custom sensor enclosure a.k.a. sensor hat that’s on the roof of the vehicles that have been Valarmed. This sensor enclosure was custom designed by my brother Lorenzo and then printed with our 3D printer – MakerGear M2! USB sensors, e.g., VOCs (volatile organic compounds) and Meteo (temperature, humidity, pressure) are protected from the elements and connected via a standard USB cable to a Samsung Galaxy S4 running the Valarm Pro app inside the vehicle. A custom Valarm Y cable allows the phone to charge at the same time as it’s talking to external USB sensor devices. Environmental sensor data is uploaded to the cloud by Valarm at customizable intervals, e.g., every minute. The sensor hat enclosure is held down to the roof of the car with magnets for easy installation.

We put together an example of how to use the Valarm JSON API to integrate this mobile sensor data into your application! (Click here to see it.)

This example was submitted for the Esri Data Viz App Challenge 2015 (we got awarded runner up!) contest and you can view the full source code here.

We pull the latest sensor data from Valarm Tools Cloud using JSONP then visualize it on a map using the Esri ArcGIS JavaScript API. Below is a video demo of the example that uses an awesome demo version of Washington, D.C., OCTO’s custom base map.

Next trip to D.C. this summer we’ll be deploying more mobile environmental sensors as well as a stationary air quality unit for monitoring particulate matter (PM2.5 & PM10), dust, pollen, and additional factors. Big thank you to City of Washington, D.C., OCTO, and the GIO for making this exciting deployment possible!

Update: Note that we recommend using GSM, WiFi, or ethernet connector devices / sensors hubs with sensors from any manufacturers, since they’re much more reliable than Androids for Industrial IoT applications like:
