Abstract

An electronic sensing system (100) located on a printed circuit board (110) is provided. The electronic sensing system including: a target gas sensor (192) configured to detect a resistance of the target gas sensor; a reference sensor (194) configured to detect a resistance of the reference sensor; a resistance comparator (400) including a digital potentiometer (160), the resistance comparator being electrically connected to the target gas sensor and the reference sensor, wherein the digital potentiometer is configured to be adjusted to determine a first resistance in response to the resistance of the target gas sensor and a second resistance in response to the resistance of the reference sensor; and a system on a chip (130) in electronic communication with the resistance comparator, the system on a chip being configured to determine a target gas concentration in response to the first resistance and the second resistance.
