IAQ Sensors

Help Improve Indoor Air Quality 


IAQ Sensors for Healthy Buildings

Some concentrations of organic chemicals are higher indoors than outdoors. In other scenarios, contaminated outdoor air may be introduced into a building through ventilation to achieve unintended consequences. Indoor air quality (IAQ) sensors support the need for sensing these pollutants and implementing ideal ventilation strategies as part of the BMS.

Our new IAQ Sensors will help improve the air within the building, creating a healthier environment for occupants. This will help improve the air in your building and create a healthier environment for your building occupants. 


Honeywell IAQ Features, Specifications, & Benefits:


Start with Precise Detection & Monitoring

Honeywell’s healthier buildings can help keep facilities safer for occupants, in part by cleaning the air automatically as people come and go. To do that, your building needs accurate data about the air quality - and that starts with our versatile range of sensors of indoor air quality (IAQ).


ALL-In-One

A multi-sensing device that contains integrated sensors for temperature, relative humidity, CO2, PM, and TVOC, while reporting values to the BMS system to provide real-time air quality monitoring. This is suitable for bench-marking and developing ventilation, filtration, and other healthy building strategies.

Total Volatile Organic Compounds

TVOC refers to the total concentration of multiple airborne VOC’s present in indoor air from a variety of sources. Using TVOC sensing indoor air quality can be assessed beyond the limitations of using CO2 as a standard metric. TVOC concentrations are up to 10 times higher indoors than outdoors, supporting the need for sensing devices and ventilation strategies as part of the BMS.

CO2 Sensors

Used for demand control ventilation (DVC) to control the amount of fresh outdoor air supplied to a space for cooling and maintaining acceptable levels of CO2. Additionally, ventilation via CO2 sensors can help minimize energy costs due to over-ventilation. Honeywell's self-calibrating and factory certified CO2 sensors ensure accuracy and compliance with CA Title 24, §120.1(d)3 and 4.




Air Quality Matters

Proper air exchange can help dispel odors, chemicals and CO2, while reducing disease transmission

Better Temperature Control

The right temperatures improve health as well as productivity.

Keep Occupants Safer

Relative humidity of 40-60% can decrease occupant exposure to infectious particles and help reduce the spread of airborne pathogens.



Disinfect with UV Light

UV-C Light can help inactivate virtual, bacterial and fungal organisms to disinfect surfaces.

Better Pressure Control

Pressure control in a space can help prevent and isolate airborne pathogens.

Cleaner Air

Air cleaners can help remove particles and clean recirculated and outdoor air.


We Can Help Turn Your Facility into a Healthy One

The past year or so has changed the world in many different ways. One of which is a new focus on healthy buildings. As we trend back to our typical way of doing business, offices, schools, and businesses will begin to open back up. And when they do, an emphasis will be put on the health and safety of the building. Let Stromquist be your source for how to transition your facility to a healthy one.
