Valarm compatible sensors 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. Edward is currently creating a CO2 page with much more information. We’ll link to it here as soon as he’s done. Perhaps the 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. Valarm allows you to monitor VOCs in real-time, record data to visualize trends, and trigger alerts at configurable levels. Check out this air quality study with the Valarm app in the Los Angeles, California, area to see which neighborhoods have healthier air.

 

In other news, we’ve dropped the price of Valarm Classic to $3 USD, and we’ve raised the price of Valarm Pro to a whopping $10 USD. For the customers who purchased early, yay! You will continue to receive updates to Valarm Pro for the entire product lifetime (forever, we hope!). Will the price go up again? Almost certainly. As we continue to develop Valarm, we will occasionally adjust the price to compensate for the rising value of our flagship product. With everything Valarm Pro does now, we still consider $10 to be a terrific value (and in fact we are frequently advised to raise the price significantly!)
