Sensor Technology
FreshAir Sensor’s advanced molecular sensor technology enables hoteliers to turn air quality from a potential liability to a revenue-generating brand asset. The FreshAir Sensor not only helps solve the smoking challenge, but also delivers the data needed to gain actionable air quality insights that unlock greater efficiency, higher revenue, and newfound levels of guest satisfaction.
Our data is enabled by unique and proprietary molecular sensor technology. We continuously monitor guest room environments for common contaminants, such as tobacco or marijuana smoke, and VOCs, as well as collecting data on temperature, humidity, etc.
It’s Pure Science
FreshAir's mission is to improve lives through novel sensor technology.
Our patented molecular sensors are based on over 20 years of research and development at Dartmouth College.
FreshAir’s Smoking Sensors immediately detect specific molecules in tobacco smoke and marijuana smoke.
Our detection system is the only technology available to monitor for and prove tobacco smoking and marijuana smoking with court-proven scientific evidence.
FreshAir’s Detection Devices continuously monitor and track additional air quality data, including temperature and relative humidity (aka conditions for mold), as well as the presence of VOCs (Volatile Organic Compounds), etc.
Our chemistry and engineering teams have an active, ongoing research and development agenda to expand the application of existing sensors and develop new sensors for other hazardous chemicals.
The science behind molecular smoking detection.
How it works
The sensors function similarly to biological receptors in the body.
The sensors are highly sensitive and specific, binding only with target molecules in tobacco smoke and marijuana smoke.
The sensors reset following smoking detection for continued monitoring.
