Industrial IoT Applications - Remote Air Quality + CO2 Sensor Monitoring

Introduction: Industrial IoT Applications - Remote Air Quality + CO2 Sensor Monitoring

About: I love remotely monitoring Industrial IoT / IIoT sensors. My favorite things is water monitoring systems, water levels / well telemetry, and flood warning systems. Questions? Please don't hesitate to get in...

**Update: The article below is from our legacy Android app! Valarm is Industrial IoT. We'll help you, your teams, and your business with Industrial IoT applications using Valarm Tools Cloud.

We recommend using GSM, WiFi, or ethernet connector devices / sensors hubs with any sensors since they're much more reliable than Androids for Industrial IoT applications like:

You can use Valarm Industrial IoT, telemetry and remote sensor monitoring solutions with any of the following connector devices:

Valarm Industrial IoT sensor data is mobile, GPS-location enabled, time-stamped, and sent to Valarm Tools Cloud / via any internet connectivity like WiFi, ethernet, or cell network. With Valarm Tools Cloud you’ll find services for mapping, graphing, and APIs like JSON to help you with your real-time, geo-enabled sensor monitoring and Industrial IoT applications.

Valarm compatible sensors and Industrial IoT hardware are available at

Have a look at our Industrial IoT Customer Stories page for more on how these remote sensor monitoring and telemetry solutions are deployed in various industries.

Learn how all of this works together on our Web Dashboards for Remote Monitoring, Telemetry, Sensors & Industrial IoT.

Please don’t hesitate to contact us if your business needs help with deploying an Industrial IoT application or have any questions!


This video shows you how to use Valarm to do remote environmental monitoring, specifically air quality and CO2.

The Valarm Tools Cloud website is where you can map, graph, analyze, and download your sensor data:

The Valarm app is available here.

You can get Valarm compatible sensors and connector hardware at

This is a Valarm compatible CO2 sensor made by Yoctopuce. The Valarm Y cable you see here allows you to charge a Sony Android device while using USB OTG to host one or more external sensors at the same time. After you have installed the Valarm Pro app plug your power in to the female micro USB end of the Y cable. This can be power from solar panels, a vehicle, or from the wall as seen in this demo. Next plug in your USB sensors, in this case we’re using an air quality carbon dioxide sensor although you can connect Valarm to any number of a variety of sensors using a standard USB hub. See for more info on currently available sensors.

Last, plug the Y cable in to your Android device and you will be prompted to launch Valarm. After you launch the Valarm Pro app use the menu button to go to the all settings screen then click Yoctopuce sensor settings. Next click the VOC (volatile organic compounds) and CO2 button. Turn on Yoctopuce sensors by clicking the button in the upper right then enable the CO2 sensor. Click the Scan All button to verify that the sensor has been detected and take sensor readings. You’ll see the current sensor value next to the help button, in this case our environment is a little over 1000 ppm CO2.

You can use the Valarm app’s interval timer to get your sensor data at regular intervals like every minute or every hour. You can also use the sliders to set your custom threshold values for minimum and maximum levels for any sensor. If a value goes above or below your specified threshold, Valarm will be triggered and can upload the alert GPS location and sensor values to the Valarm Tools website at You can also receive alerts via text message and email. See Valarm’s other videos for step-by-step instructions on linking your Valarm devices to the Valarm Tools Cloud.

If you breathe on the sensor and scan values again you’ll verify everything is connected properly and see a rise in CO2 levels.

Now your Valarm device is ready to be deployed for remote monitoring! Go back to the home screen to arm Valarm. Now that Valarm is armed and deployed you will see all of your Valarm data in real time on the Valarm Tools website at You can also receive alerts when there is a max or min trigger. See Valarm’s other videos for instructions on how to link all of your sensor data to the Valarm Tools Cloud at as well as how to configure text message and email alerts from Valarm.
