“Smelling” when crops are ripe or food is burning

Stratuscent presents Digital Nose

At this year’s tech expo CES this week, digital noses are becoming a bit of a thing. At the Stratuscent booth, a Montreal, Quebec-based startup which is digitizing scents to detect freshness, they showed their eNoses, sensors that detect chemicals in the air to create a scent print — like a fingerprint for a smell.

According to CEO David Wu, who gave me a tour, Stratuscent’s “secret sauce” is its superior AI and machine learning, which can quickly and accurately determine any number of complex scents, even ones too tricky for humans to smell. The company’s tech came from NASA, where it was originally used for leak detection.

The eNose is pretty simple to use. Just wave the product in question under the eNose and it will determine what it is — as well as its percentage of accuracy — in under thirty seconds. You can see Wu demonstrating the technology below:

Stratuscent isn’t the only player digitizing smell technology. The Aryballe company has their new Digital Nose 2.0, which also debuted at CES this week and also digitizes scent to detect freshness, cooking smells, etc.
