    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)



This video shows you how easy it is to do air quality monitoring with Valarm! You’ll see the VOC (volatile organic compounds) sensor in this video but keep in mind that Valarm is compatible with thousands of sensors using standard sensor signals like 4-20 mA and 0-10 V. There’s also radiation and PM2.5 / dust / pollen sensors compatible with the Valarm Pro app. Have a look at the video above and don’t hesitate to contact us if you have any questions!

You can get Valarm compatible sensors at shop.valarm.net and all of your real-time sensor data will be available in the Valarm Tools Cloud at tools.valarm.net.

Video transcript / voiceover:

Hello, this is Edward from Valarm. In this video you’ll see how to use Valarm for remote environmental monitoring. There are thousands of sensors compatible with Valarm monitoring solutions. In this video we’ll focus on air quality and sensors for volatile organic compounds, or VOCs.

What you’re seeing here is a Valarm compatible Yoctopuce VOC sensor. Perhaps you need to monitor air quality indoors, or outdoors. With Valarm, you can literally monitor anything, anywhere. Here you’ll see how to use the Valarm Pro Android app and Yoctopuce USB sensors to have affordable, real-time, mobile sensors to perform remote environmental monitoring.

In this demo setup you see a Sony Android device running the Valarm Pro app, a Yoctopuce USB VOC sensor, and a Valarm OTG + Charging Y-cable that allows an Android device to talk to external sensors at the same time as charging.

First we’ll plug the Valarm Y cable (USB Host OTG+Charge) into the power source, then the VOC sensor, and last into the Valarm connector hardware. When the sensor is detected, you’ll be asked if you want to launch the Valarm app. Click ok to launch the app then use your device’s menu button to go to All Settings then Yoctopuce, then VOC and CO2. Be sure to Enable Yoctopuce sensors at the top of the screen if you haven’t already. Then you can click Scan All to verify all of your sensors are properly connected. You can see the VOC vppm values are being reported so we’ll turn on the VOC sensor to have its values reported to the Valarm Tools Cloud. Now I’ll breathe some of my volatile organic compounds from my mouth onto the sensor. Scanning the sensor values now reports a much higher value of VOCs, time to brush my teeth! Note that you can also set hi and lo threshold values using the sliders for any sensor.

Now go back to the All Settings screen and turn on the interval timer. This tells Valarm to gather all sensor values at the custom time interval you set, for example, every 60 seconds or every hour.

Your last step is to turn on Valarm Web Integration and link the device to the http://tools.valarm.net website. Then we’ll be able to map, graph, analyze, and download all of our sensor data from the Valarm Tools Cloud. Use your Valarm Tools login info then your geo-tagged sensor data will be uploaded to the cloud in real-time. For step-by-step instructions on how to do this, watch Valarm’s YouTube video tutorial on linking devices to the web.

We’ve got everything configured, now we’re ready to arm Valarm by clicking Arm on the app’s home screen. Now that Valarm has been deployed and armed, the sensor data is being sent in real-time to the Valarm Tools Cloud website using the device’s internet connection: 3G/4G cell network, WiFi, or any other connection. I’ll affect the VOC air quality sensor readings here by putting my toxic breath onto the VOC sensor.

At any moment you can see your real-time Valarm sensor data on any computer connected to the internet by logging into your account at http://tools.valarm.net . Once you’re logged in go to your device in the Device Manager to see your latest geo-tagged sensor data. Here you’ll see the latitude and longitude coordinates associated with every sensor reading, in this case you see sensor data collected every 3 seconds.

Click graph sensors then check your sensors of interest to see an interactive graphic of your sensor data. Hover your mouse over the graph to see exact values at that point.

See Valarm’s other videos to learn how to export your sensor data in 3D formats like KML. Here is some sample Valarm VOC data gathered from the roof of a public transit bus driving its route around Los Angeles, California. All of your geo-tagged sensor data is available here and the heights of each data collection point are the VOC air quality sensor reading for that location.

Now you know how easy it is to deploy Valarm’s real-time, mobile sensors for remote environmental monitoring, so get out there and do it! Don’t hesitate to contact us at info@valarm.net if you have any questions, comments, or suggestions for another video.
