Verkada SV21 Air Quality Sensor
SV21 Datasheet
Overview
The SV21 air quality sensor is a cloud-managed device for monitoring indoor air quality and ambient environment conditions. It specifically measures temperature, relative humidity, and carbon dioxide. The SV21 additionally offers readings for indices like Heat Index, Humidex, Mold Risk Index, and Dew Point Index, which each represent a unique composite of temperature and relative humidity.
This sensor is well suited for environments like IDF/MDF closets, server rooms, and cold storage areas, where regulating temperature and protecting food, inventory, and networking infrastructure is paramount.
Organizations additionally benefit from alerts for offline devices, 24/7 support, and automatic firmware updates, helping to ensure their sensors are operational and improving over time.

Reading Overview | Ambient Environment Indicators
Temperature
SV25 temperature measurements are accurate from 23°F - 122°F (-5 – 45°C). As with other data streams, users can customize temperature alerts if a space is kept at a temperature outside of the recommended green zone.
Relative Humidity
Relative humidity is the amount of moisture in the air compared to what the air can hold at that temperature.
Heat Index
The heat index represents what the temperature feels like to the human body when relative humidity is combined with the temperature. It is derived from our existing temperature and humidity readings and uses the National Weather Service's heat index chart to calculate the reading value.
Humidex
Similar to the heat index and commonly used in Canada, Humidex indicates how hot it feels to the average person. It is calculated using a formula developed by Canadian meteorologists.
Dew Point Index
Dew point is the temperature at which air cools enough for water vapor to condense into dew or frost. Industries from transportation to agriculture often use this index to predict and mitigate risks from conditions like frost or fog.
Mold Risk Index
The Mold Risk Index assesses the likelihood of mold growth in confined, unventilated spaces based on temperature and humidity levels. Higher temperatures combined with elevated humidity create ideal conditions for mold spores to thrive, making these factors key indicators of potential mold growth.
Carbon Dioxide (CO2)
CO2 measurements capture the absolute level of CO2 in an environment. At levels of 800ppm or less, CO2 is harmless. Between 800 and 2000ppm, CO2 levels can be harmful to health, at levels above 2000ppm, CO2 can be extremely harmful to human health.
Tamper Detection
Indicates if your device has been moved or tampered with.
