ABSTRACT:
An apparatus for sensing a constituent in an environment including a sensor circuit and a suppression circuit. The sensor circuit has a sensor element and an operating state control element. The sensor element senses the constituent by presenting an electrical parameter which varies as a function of a degree of the constituent. The control element maintains the sensor at a preferred operating state. A detected electrical parameter of said sensor element is subject to error resulting from a leakage of electrical current between the control element and the sensor element. The suppression circuit reduces or stops the leakage to reduce the error.
