OCISense Breath
N2O NDIR gas sensor

Miniaturized infrared spectroscopy sensors dedicated to nitrous oxide, gas measurement in breath air.

What is OCISense?

OCISense is an advanced infrared spectrometer designed for the accurate analysis of volatile organic compounds (VOCs) in exhaled and ambient air. The OCISense is designed to detect and quantify N2O molecules in exhaled air, providing valuable insights into respiratory health.


The measurement chamber of the sensor is ingeniously designed to be crossed by infrared radiation. As exhaled air flows through this chamber, the molecules of interest selectively absorb specific wavelengths of the radiation, resulting in a perceptible reduction in the optical signal. Based on the principles of Beer-Lambert’s law, the sensor accurately deduces the concentrations of these gases, providing essential data to help medical diagnosis, improving patient care and outcomes.
