Figaro Engineering Inc. is pleased to announce our latest development, the Ventilation Index Sensor TGS2660. This sensor’s output has a high correlation with indoor air contaminant level caused by occupants. It is in the final stage of development and is set for release soon.

The sensing element is comprised of a metal oxide semiconductor layer formed on an alumina substrate of a sensing chip together with an integrated heater. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.

Thanks to the high correlation between the sensor output and the air contaminants level affected by occupants in a room, TGS2660 is useful for ventilation control and ventilation index monitors. With its compact size, this sensor is the ideal choice for size-oriented applications such as ventilation fans in offices and living areas, and kitchen range hoods.
