Update: Below there is some info from our legacy Android app. For your business, government agency, or other organization’s CO2 monitoring needs, we recommend you use our CO2 Air Quality Monitoring Package from at Shop.Valarm.net since dedicated sensor hubs are the most reliable, power-efficient, flexible, and effective.

Does your organization need to monitor air quality?

Take a gander at this Industrial IoT application that our customers deploy in the states monitor CH4 / Methane along with weather and sound / noise sensors.

See this story about how air quality is monitored in California. These air quality monitoring systems are used by government agencies like the California Air Resources Board / CARB.

Also have a look at this Industrial IoT / IIoT Customer Story on how we work with South Coast Air Quality Management District (SC – AQMD), the California government agency responsible for air quality monitoring and compliance in Los Angeles, Orange County, and the majority of Southern California.

Your organization can easily + effectively monitor particulate matter, like PM1, PM2.5, PM10, as well as specific gases like O3 / Ozone, NO2 / Nitrogen Dioxide, H2S / Hydrogen Sulfide, SO2 / Sulfur Dioxide, NOx / other Nitrogen Dioxides, CH4 / Methane, and any other gases and air quality factors you need to measure.

Have a look at our Industrial IoT Applications on our Customer Success Stories page for more on how these sensor solutions are used by businesses and organizations in over 45 countries around the world to monitor things like:

Your sensor readings are measured, GPS-tagged, time-stamped, and sent to Tools.Valarm.net via any internet connectivity like WiFi, ethernet, or cell network.

On Tools.Valarm.net you’ll find services for mapping, graphing, and APIs to help you with your real-time, geo-enabled sensor monitoring and Industrial IoT solutions.

Valarm compatible sensors and Industrial IoT hardware are available at Shop.Valarm.net.

Late last week we released v1.2 of Valarm Pro, which includes support for the Yoctopuce Yocto-CO2 and Yocto-VOC. These two new sensors bring indoor (and outdoor) air-quality monitoring to Valarm, along with a host of possibilities and important use cases.

Some common users of CO2:

  • Hydroponic growers (and to some degree aquaponics) frequently supplement CO2
  • Captive reef aquarium facilities are also users of supplemental CO2

Some common producers:

  • Brewery and winemaking operations are significant producers of CO2
  • Humans in poorly-ventilated enclosed spaces like boardrooms, classrooms, music practice rooms, recording booths, and small music or video editing studios

Monitoring CO2, whether you’re using it for agricultural or ornamental purposes, or producing it due to industrial or food production activities, or simply living and working in enclosed spaces of any kind – can be critical for human health, productivity, and creativity.

Your most important info: late last year the highly respected Lawrence Berkeley Labs released a study that shows in frightening numbers just how negatively CO2 affects human mental performance! We’re talking about CO2 in a not-unusual boardroom, classroom, studio, or other enclosed space full of people.

The Yocto VOC USB sensor

Also in this latest release of Valarm Pro: VOCs or Volatile Organic Compounds can now be monitored and alerted upon like our other sensors.

VOCs detectable by the Yocto-VOC include alcohols, aldehydes, aliphatic hydro-carbons, amines, aromatic hydro-carbons (e.g. gasoline vapors), carbon oxides, methane, LPG, ketones, and organic acids.

All of these substances are seriously harmful to human health.

Industrial IoT sensor monitoring systems allow you to monitor VOCs in real-time, record data to visualize trends, and trigger alerts at configurable levels.

Check out this air quality study in the Los Angeles, California, area to see which neighborhoods have healthier air.
