摘要:
A pair of pollution sensors which react oppositely to exposure to respective different pollutants are connected together in one or more voltage-divider circuits so that a combined output voltage always becomes either more negative or more positive regardless of which sensor is responding to the presence of the respective pollutant. For example, a tin-dioxide sensor for gasoline exhaust and a tungsten-trioxide sensor for diesel exhaust can be connected in series as a voltage divider with a center tap connected to an evaluating circuit.
