GAS SENSOR WITH HEATER

摘要

A first embodiment of a disclosed breath analyzer detects a particular breath component in a breath sample. The analyzer includes a housing defining an interior cavity and having an inlet aperture for receiving the breath sample and an outlet aperture. A sensor is disposed within the cavity for sensing the component of the breath sample. An anemometer circuit is associated with the sensor and measures a rate of flow of the breath sample within the housing. The analyzer further includes a controller operatively connected to the sensor to receive breath component information sensed by the sensor.
