CO2 Sensor and flow meter


Lumen uses a CO2 sensor and flow meter to determine the CO2 concentration in a single breath. This indicates the type of fuel your body is using to produce energy and allows you to make smart nutritional decisions to consume more or less of the macronutrients your body is needing more or less of at a specific time, such as before or after training. Historical data can be reviewed in the app letting you and your coach analyse trends in how your metabolism evolves. This enables you to lose weight and gain performance more efficiently and effectively.
