Abstract
The invention discloses a method and a system (100) of operating a gas sensor 10 in a portable electronic device (50). The gas sensor (10) operates in an ultra-low power mode when the portable electronic device (50) is inactive and the gas sensor (10) operates in a normal power mode when the portable electronic device (50) is active. The method involves storing a baseline resistance value of the gas sensor (10) in the ultra-low power mode.

A rate of stabilization of resistance value of the gas sensor (10) is computed in the normal power mode. A stabilized resistance value of the gas sensor (10) in the normal power mode is estimated based on the rate of stabilization of resistance value of the gas sensor (10) in the normal power mode, the baseline resistance value in the ultra-low power mode and a comparison chart of stabilized resistance values of the gas sensor (10) in the ultra-low power mode and the normal power mode.
