Sensor Technology

Trust the only sensor technology to monitor for and specifically detect tobacco and marijuana smoke.

Leverage proprietary molecular technology based on 20 years of Ivy League research funded by the National Institute of Health.

Monitor, detect, and prove in-room tobacco and/or marijuana smoking with court-proven data.

Eliminate false alarms and common excuses (candles, incense, burning foods, steam, smoke odors, fragrances, etc.).

FreshAir Matters

It’s Pure Science

  • FreshAir Sensor’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 Sensor is the only solution to specifically monitor for, immediately detect, and scientifically prove in-room burning tobacco and/or 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.

  • Our molecular sensors continuously monitor and track additional air quality data, including temperature and relative humidity (aka conditions for mold), with unique occupancy and vaping sensor capabilities in final development.

  • 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 sensor functions 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.

Accuracy Matters

Discrete Alerts

Enforce, Enhance, and Save

Enforce smoking policies, enhance the guest experience, and save on cleaning costs with data alerts and scientific evidence any time unauthorized smoking of tobacco and/or marijuana occurs.
