Abstract
A sensor apparatus incorporates a responding gas sensor to measure and display gas concentrations or other indications. Calculation of a gas concentration may be derived from an output signal of a light detector through the use of a linear equation. Through the use of digital processing an output signal may be sampled to calculate a gas concentration based on a rate of change of the output voltage.
