The South Coast Air Quality Management District (SC-AQMD) is the air pollution control agency for all of Orange County and urban Los Angeles, Riverside, and San Bernardino counties. That’s 1 of the most critical areas to monitor air quality for your and everyone else’s health! We’re excited to be working together with AQMD to monitor particle and gaseous pollutants in the south coast air basin.

We put together this video tutorial to show you how rapidly you, your teams, organization or business can deploy Valarm Tools Cloud software with air quality sensors made by Alphasense that are attached to an echem328 circuit board made by CircuitSci. If you need to monitor Particulate Matter (PM1, PM2.5, PM10) then see here how you can do that with a SPI sensor adapter and Valarm Tools Cloud.

The sensors hubs and serial sensor adapters you see in the video are available at

Howdy! This is Edward from Valarm. In this video you’ll learn how to rapidly deploy Industrial IoT applications for air quality monitoring. We’ll be adding telemetry to Alphasense air quality sensors, like the ozone and nitrogen dioxide sensor you see in this video tutorial. There are lots of other air quality sensors available that will work with Valarm in the same way like Hydrogen sulfide, H2S, carbon monoxide, sulfur dioxide, and plenty more. We’re happy to help you so please don’t hesitate to contact us at info { at } if you need to monitor air quality.

Here you see the hardware you’ll need to get your air quality sensor data in Valarm Tools Cloud at There’s an Alphasense Ozone and Nitrogen Dioxide, aka NO2, sensor that’s connected to an echem328 circuit board made by CircuitSci. This air quality sensor information is read by this serial sensor adapter that’s connected to the appropriate channels on the sensor circuit board for receive (RX / RD), transmit (TX / TD), ground, and power. The serial sensor adapter is connected to a sensor hub that connects to the internet via GSM mobile cell network, WiFi, or ethernet. If you need serial sensor adapters or sensor hub connector devices, you can find them on

After you’ve got these components connected your air quality sensor data is available at for mapping, graphing, exporting, analysis, and forwarding via our APIs. Note that you can also add a GPS if you’d like to do mobile air quality monitoring.

If you haven’t gotten credits or linked your sensor hub to Valarm Tools Cloud then see our other how to tutorials and videos on to get your sensor hubs connected to

Once you’ve got your air quality sensors and sensor hubs linked to Valarm Tools Cloud, you can map the air quality sensor readings to Valarm Tools fields. You’ll do this with the CSV input menu under Configure Data Path. The Alphasense air quality sensor readings are coming in from the serial sensor adapter as CSV, or comma separated values. This the order of the air quality sensor values coming in to Valarm Tools Cloud : INDEX, TIME, PPM, PPMf, PPMaux, TEMPf, TEMP, WEf, AUXf, Vin, Vdd, Vref, Vwe, Vaux, sens, zero, aux. Map the index of the sensor values you need to your desired fields like you see in this example where we’re mapping the ppm values to Valarm fields.

That’s it! Now all of your air quality sensor data is available throughout like on graphs which you’re seeing here. You can map your remote monitoring data and see your GPS-tagged, real-time mobile air quality sensor data. It’s also easy for you to forward the sensor telemetry information to your dashboards or business intelligence and analytics systems, like Esri ArcGIS, by using our JSON API.

If you, your teams at your organization or business need real-time Industrial IoT sensor data on web dashboards, send us message and we’ll help you get it done. If you need to receive threshold alerts or have any other remote monitoring needs, or have a request for another video, then please, don’t hesitate contact us on our website at, or email us any questions!


UPDATE: Also have a look at the SPI sensor adapter that you can use with Alphasense OPC-N2 particulate matter air quality sensors and sensor hubs like 3G GSM, GPRS / 2G, WiFi, and ethernet.

Use your sensors hubs and this SPI sensor adapter with your Alphasense OPC-N2 sensors to get your real-time, geo-tagged air quality sensor data on maps, graphs, interactive dashboards, and however else you want it at Valarm Tools Cloud
