Comfort That Lasts! Compare CO2 & Humidity Sensors for Your Space
Is it a seasonal scramble to keep your building comfortable? The key to stable indoor comfort lies in how you monitor your environment. You can fight some of the most common culprits of discomfort, like rising summer humidity and poorly ventilated rooms, with two proven Veris sensor lines — our CO₂ sensors and humidity sensors — which we’ve designed for control, consistency, and confidence in every zone.
Sensors for monitoring CO₂ and humidity support both occupant comfort and energy-efficient operations. You’ll avoid unnecessary runtime and over-ventilation with easy, real-time insights into your HVAC systems. In the end, that gives you the confidence you need to adjust schedules and setpoints in ways that reduce costs, extend equipment life, and better support compliance with evolving building codes.
The wall and duct-mounted sensors below are perfect for simplifying upgrades and retrofits for school facilities, commercial offices, or healthcare environments. Learn more about them and how you can get precision and peace of mind with Veris!

How to Monitor CO2 Levels with Veris Sensors
Poor circulation of indoor air can impact productivity, comfort, and even occupant health. However, over-ventilation can mean high energy costs that are unnecessary. The upgraded CW2 Series sensors from Veris give you everything you need to properly track and manage CO2 levels for a safe, compliant, and welcoming indoor environment.
6 Benefits of a Wall-Mount Humidity Sensor
We often think about temperature and CO2 levels when tracking indoor air quality, but humidity is equally important to track and control. In fact, for some environments, the relative humidity (RH) can have a significant impact on equipment lifespans or regulatory compliance with IAQ standards. Here are six major benefits of installing wall-mount humidity sensors from Veris within your facility.
