Sensor Technology

Sensors for tobacco and marijuana smoking in hotels and apartments


PolySens® Technology

FreshAir's mission is to improve lives through novel sensor technology
Our patented polymer sensors are based on over 20 years of research and development
PolySens® technology immediately detects 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 in hotels and apartments
Our chemistry and engineering teams have an active, on-going research and development agenda to expand the application of existing sensors and develop new sensors for other hazardous chemicals

How It Works

The science behind the smoking sensors

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
