Indoor air quality (IAQ) directly impacts the comfort, health, and safety of your building’s occupants. Poor air quality management can lead to significant short and long term health risks for occupants, as well as reduced productivity and concentration. Code compliance and legal scenarios also hang in the balance for a wide range of public and private indoor environments, such as educational facilities. Investing in precision air quality testing equipment helps ensure you are prepared.
To ensure a healthy and productive environment, you need full-time air quality monitors in place for all occupied areas and other climate-sensitive environments (chemical storage, library archives, museum displays, animal habitats, etc.).
The right indoor air quality sensors can track all of the necessary variables from temperature and RH to airflow measurement and the presence of harmful but odorless contaminants like CO2 or irritating VOCs. Armed with a continuous data model of your building’s IAQ, you can make informed decisions that will optimize your BAS for efficiency and your HVAC schedule for maximum occupant comfort.
Continuous IAQ testing will also give you critical insights into the health and maintenance needs of your building’s HVAC systems. Smart indoor air quality products not only alert you to substandard environments, but provide helpful feedback about the condition or effectiveness of the systems that are regulating it. The more data you have, the easier it will be to maintain compliance and comfort while saving time and money through preventative action.

According to OSHA, the most common causes of subpar IAQ include:
Of further concern is the fact that many indoor air pollutants have no smell. It’s easy for substances like CO2 or irritating VOCs to develop undetected until occupants experience symptoms like headaches, fatigue, sleepiness, or other respiratory issues. If these side-effects have begun to appear, you may have a problem with IAQ.
Other factors can also play a role in the way your occupants feel about indoor air quality standards. For example, things like odors, inconsistent temperature, air pressure (drafts or stuffiness), added heat from unfiltered sunlight, and more can affect the comfort of the indoor environment and require remediation from air quality management systems.
Properly maintained and updated ventilation, heating, and cooling systems are important. However, they’re only as useful as your ability to manage setpoints, automate a schedule, track performance, predict needs, and respond to deficiencies.
The best approach to measuring indoor air quality is to deploy an integrated network of indoor air quality sensors with a combination of RH, temperature, and VOC outputs in all sensitive locations. Comprehensive data from numerous indoor air quality monitor devices will help maintain a reliable environment. A safe, compliant, and comfortable indoor climate ensures that your building and its occupants will thrive.
Among other things, air quality sensors are used to:
With modern IAQ sensors, it’s even possible to remotely monitor indoor air quality and adjust fan, thermostat, or ventilation schedules from any location. A remote-enabled sensor system, such as the IAQ sensors made by Veris, makes your job easier and more efficient. You’ll be able to save on costs, prevent waste, minimize downtime, and meet compliance standards with a simple and highly compatible indoor air quality sensor system.
Whereas temperature and humidity are easy to feel, gas emissions are difficult to detect—and can cause discomfort . It’s important to monitor the concentration of airborne pollutants with a carbon dioxide sensor, preferably with the ability to detect volatile organic compounds (VOCs), carbon monoxide, and nitrogen oxide as well. Here are a few priorities to set when evaluating CO2 wall mount sensors, duct CO2 sensors, and more:
An innovative CO sensor, NO2 sensor, CO/NO2 sensor or Refrigerant Sensor will drastically reduce project costs for critical environments like parking garages, sally ports, and similar structures. The remote CO2 sensors from Veris offer several important advantages. You’ll be able to tell instantly, from a distance, if you need to:
At the same time, Veris sensors give you incredible flexibility and compatibility with removable terminal blocks and the ability to integrate into a variety of control systems (4-20mA, 0-5V, or 0-10V, BACnet MSTP and Modbus RTU). Take a closer look at these leading carbon dioxide and VOC sensors in our CW2 series of CO2 and VOC sensors:
Temperature sensors are critical to monitoring the comfort of living and working spaces, but also for protecting temperature-sensitive materials or environments from mishaps. Many indoor temperature sensors focus on air temperature, but this is only one aspect of ensuring a compliant, safe, and comfortable environment. Pipe temperature sensors, for instance, help to ensure safe and optimal water temperatures (and to predict maintenance issues with heating systems) .
Here are a few priorities to set when evaluating wall mount temperature sensors, duct temperature sensors, discharge air temperature sensors, and other HVAC temperature sensors:
Veris makes temperature sensors for your every need, including: wall, duct, outdoor, averaging, pipe/immersion, discharge air, contact/strap-on, button, ceiling, and more. With the advantages offered by our indoor temperature sensors, you’ll be able to:
With the help of temperature sensing devices, climate-dependent locations like museums, schools, printing shops, hospitals, data centers, and others can protect sensitive materials and stay ASHRAE compliant while also ensuring maximum occupant comfort. The best results will come from averaging temperature sensors over time in a continuous, multi-sensor system that models long-term trends and predicts future needs. Take a closer look at these leading wall temperature sensors in our TW2 series of temperature sensors:
Few indoor air quality sensor platforms can offer the same advanced precision and robust data models, which will help keep building occupants comfortable and temperature-sensitive environments or materials safe.
Humidity sensing systems are an often overlooked area of building climate control, but quality humidity sensors are no less essential than thermostats, CO2 sensors, fire detectors, VOC sensors, and the like. The relative humidity (RH) of an indoor environment impacts occupant comfort, personal safety, and even the integrity of sensitive materials or equipment. For example, hospitals with high humidity are at risk of breeding mold or creating environments conducive to pathogen growth. A laboratory setting, on the other hand, may require higher humidity than most people find comfortable.
A network of humidity sensors helps you to better optimize the RH of your indoor climate. Here are a few priorities to set when evaluating humidistats, duct humidity sensors, wall humidity sensors, and more:
The Veris HW2 series of indoor RH sensors was designed to bring all of these qualities to a simple, easy-to-install wall humidity sensor. You’ll also have the freedom to select from three interface options to suit your needs, including a color touchscreen, three-button LCD display, or a subtle non-display (blank face) sensor that’s exclusively controlled through the BAS. Veris humidity sensors can be used to:
A detailed long-term data model of the indoor climate, from a multi-sensor system, is the best way to monitor and maintain a consistent, comfortable, or ideal atmosphere in climate-dependent facilities. If you’re looking for an efficient humidity sensing solution, take a closer look at these leading wall humidity sensors in our HW2 series of humidity sensors:
Your complete network of indoor air quality sensors will likely include devices in a wide range of locations, from room sensors in highly trafficked lobby areas to duct sensors in remote maintenance areas or unreachable wall sensors near the ceiling of large rooms. For this reason, it’s best to use a sensor platform that offers a choice of interfaces to suit the needs of each individual device.
The Veris IAQ room sensor platform, for instance, offers these three interface options:
It’s possible to mix and match sensor interfaces throughout your installation, so that each device is optimized for the context. If you need more information, check out our brief guide on choosing an IAQ sensor platform.
