GAS SENSOR DYNAMIC ENVIRONMENTAL COMPENSATION USING AUTO-CALIBRATION METHOD

A gas sensor system and a method of operating the gas sensor system can include a group of sensors and a microcontroller that can receive sensor measurements from the group of sensors. Feedback from the group of sensors can generate a sensor offset and a pulse width modulation (PWM) demodulator can...

Beschreibung
Zusammenfassung:	A gas sensor system and a method of operating the gas sensor system can include a group of sensors and a microcontroller that can receive sensor measurements from the group of sensors. Feedback from the group of sensors can generate a sensor offset and a pulse width modulation (PWM) demodulator can be varied to reduce the sensor offset to null and provide sensor-to-sensor variations, which are independent of error in the sensor measurements.
