Howdy! This is Edward Pultar from Valarm.

In this video you’ll see how organizations use, to remotely monitor air quality like specific gases and particulate matter.

We’ll go through key components inside of Valarm air quality monitoring units that are deployed in the field. gives you all the tools you’ll need to monitor any brand of Industrial IoT sensors, like sensors that measure specific gases like ozone / O3, nitrogen oxides / NOx, hydrogen sulfide / H2S, Sulfur dioxide / SO2, dust, and particulate matter like PM1, PM2.5, and PM10.

Once your Valarm units are deployed in the field then all of your real-time air quality sensor information is available on graphs, dashboards, 2D and 3D maps, and anywhere else you need it via our APIs.

You’ll see remote monitoring units in this video that use sensor hubs with any internet connectivity, WiFi, 3G mobile cell network, or ethernet to send air quality sensor data to You’ll also see that these telemetry boxes can be powered by any source, like standard mains wall power or solar panel power.

These Valarm air quality units monitor specific gas sensors made by Alphasense for measuring ppms / parts per million of O3 a.k.a. Ozone and NO2 a.k.a. Nitrogen Dioxide. There is also an Alphasense OPC-N2 in each box, which is an optical particle counter for measuring particle pollution in the air like dust and particulate matter of different sizes in micrometers, like PM1, PM2.5, and PM10.

These boxes were made together with the air quality scientists and technicians at the Southern California Air Quality Management District, a.k.a. SC-AQMD or just AQMD. The Alphasense sensors AQMD chose for these boxes were run through rigorous tests in their air quality sensor performance evaluation center (AQ-SPEC), so these air quality sensors have proven their effectiveness according to government standards. They’re pretty darn good when compared to the price of US EPA standard sensors that can cost many, many times more.

You’ll see the specific gas sensors are located at the bottom of each box. They’re exposed to ambient air in the bottom of the box. A rubber O ring protects the contents inside of the box while the Alphasense air quality sensors measure and monitor the real world air quality conditions.

There are fans inside the boxes to keep air flowing and keep the boxes from reaching any extreme temperatures. A meteo sensor (micro-climate weather station sensor) in each unit monitors temperature, humidity, and pressure at all times, which is useful for calibrating and curve adjusting air quality sensor data.

The particulate matter sensors in each of these boxes are Alphasense OPC-N2 Optical Particle Counters. This air quality sensor has a forced air intake fan and uses a laser to measure and count particle pollution, dust, and particulate matter like PM1, PM2.5, and PM10. AQMD chose this sensor due to its excellent combination of cost-effectiveness and accuracy. The OPC-N2 particulate matter sensors are located in the top of the boxes and air goes into the sensor through a 90 degree aluminum pipe that keeps out rain, snow, and precipitation, yet allows ambient air into the sensor for monitoring.

Your organization can see air quality sensor information on web dashboards, which you can view on any device with a web browser, like your phone or tablet.

If you’ve got a GPS / GNSS sensor installed with each of your units then your sensor information will be geo-tagged and visible on maps in 2D and 3D. You can see the GPS unit installed in these boxes is located towards the top of the box. The GPS also provides a more accurate time stamp for air quality sensor data, which is critical for the air quality scientists at AQMD who need really accurate Industrial IoT Sensor Time Stamps.

So whether you’re monitoring air quality with boxes that are stationary or mobile you’ll likely want to include a GPS sensor. Remember that you can use hardware from just about any sensor manufacturer (especially those that use international sensor standards, like 4-20mA and 0-10V, with, we’re an open platform. So if you’ve got a specific brand of sensor you want or already have deployed on your assets like trucks, then we can help you deploy the best remote monitoring solution for your specific needs.
