  • Indoor air quality sensor and method
    Patent number: 5394934
    Abstract: An indoor air quality sensor designed to be utilized in a zone of a building to control the ventilation of the zone and the method of effecting such control. The sensor comprises a first sensor for sensing a selected leading indicator of contamination in the zone and providing an output signal representative thereof and at least one additional sensor for sensing at least one selected secondary indicator of contamination in the zone and providing an output signal representative thereof. A processor, utilized for generating an output signal representative of the indoor air quality in the zone, receives the output signals from the first sensor and the least one additional sensor and generates the output signal representative of the indoor air quality in the zone by influencing the output of the first sensor by an amount that is a function of the output signal of the least one additional sensor.
