What’s new in the SV20 series

What’s new in the SV20 series

Updated over a week ago

Beginning in November 2022 the Air Quality Sensors product lineup will feature 3 New devices, that have slight variability between each other and our previous model. This guide should help explore the different features in a general sense and what has changed. For further questions please reach out to [email protected] or your account owner for more information.

SV21 - a low-cost sensor easily scalable for deployment in conference rooms and office spaces.

SV23 - an all-around air quality monitor best for smoke and vape detection in bathrooms or other sensitive spaces.

SV25 - our heavyweight sensor that combines several essential monitoring devices in a single easy to deploy package.

All sensors in the lineup will now include a carbon dioxide sensor. CO2 monitoring has been a big ask, and it’s not hard to see why.

Unfortunately, many buildings suffer from poor ventilation and have high levels of CO2 or other pollutants, which have been linked to higher virus transmission rates or even just making it difficult to focus.


The new lineup of sensors now support the ability to be mounted to walls without sacrificing precision in temperature readings or air quality readings. For installations like CO2 monitoring low-level wall mounting is actually required; however, for vape and smoke detection ceiling mounting is still required.

TVOC measurements are now reported as a more qualitative Index

Total Volatile Organic Compounds (TVOCs) are carbon-based or organic chemicals that evaporate into the air. Concentrations were previously reported as ppb (parts per billion) which is an air concentration. TVOCs include a long list of chemicals with widely different vapor pressures that may impact this reading as compared to what you may smell in the room. TVOCs are now reported as an index in respect to a moving average. The TVOC Index mimics a human nose’s perception of odors with a relative intensity compared to recent history. The TVOC Index is also sensitive to odorless VOCs, but it cannot discriminate between them. This allows for data to be more quantitive and easier to understand; a high TVOC index reading would be indicative of a lingering odor.

Additional New Sensors

With the SV25, we now offer more sensors for all-in-one air quality monitoring on a single device.

4 new sensors are available with the release of the SV25:

Carbon Dioxide (CO2)

Carbon dioxide (CO2) is a colorless and odorless gas that’s produced both naturally like people breathing and through human activities such as burning gasoline, wood, or oil. Indoor CO2 levels are dependent on factors such as the number of people present, the amount of time an area has been occupied, the amount of fresh air entering the space, the size of the room, and nearby combustion by-products.

Measuring CO2 has become a common way to determine the air quality of an indoor space and a way to determine how good the ventilation is in a room.

Carbon Monoxide (CO)

Carbon monoxide (CO) is an odorless, colorless, and toxic gas. Common sources of CO are automobile exhaust, gas stoves, leaking chimneys and furnaces, and generators. Because it is impossible to see, taste or smell the toxic fumes, CO can be deadly and the presence in a building can be unknown.

The effects of CO exposure can vary greatly from person to person depending on age, overall health, and the concentration and length of exposure.

Formaldehyde (CH2O)

Formaldehyde is a colorless, flammable gas at room temperature and has a strong odor. Exposure to formaldehyde may cause adverse health effects. Common sources of formaldehyde are resins used to manufacture composite wood products, building materials, insulation, and household products such as flues, paints, lacquers, fertilizers, pesticides, and old furniture.

Barometric Pressure

Increasing pressure tells us higher pressure is coming and skies will clear up, while decreasing pressure signals a low pressure system is on its way bringing clouds and possibly rain. In addition to knowing about approaching weather, monitoring pressure changes at home can help you understand your joint pain and headaches or migraines.

There are no thresholds or warning levels in Command for Barometric Pressure because thresholds will depend on altitude.

Ambient Light

Ambient light is a measure of how much natural (e.i., sunlight, moonlight) and artificial (e.i., lamps, interior lighting, etc.) light is in a given area. The amount of light an individual is exposed to could cause physical discomfort.

Knowing ambient light levels in a space can help point out energy inefficiencies and improve overall energy consumption. There are no thresholds or warning levels in Command for ambient light because thresholds will depend on your environment and installation.
