Sensirion SBN41 Breath Analysis Sensors - Coming Soon
Sensirion SBN41 Breath Analysis Sensors are miniaturized respiratory gas exchange sensors that deliver real-time, breath-by-breath analysis of O2 and CO2 with medical-grade accuracy in a compact form factor. Built to handle the dynamic conditions of human breath, the Sensirion SBN41 enables portable indirect calorimetry and advanced metabolic monitoring, bringing lab-quality insights to wearables and smart devices. These compact sensors deliver full respiratory gas exchange data required for accurate VO2, VCO2, and RER calculation. The SBN41 sensors maintain precise measurements even under rapid changes in temperature, humidity, and gas composition at high breathing rates.
