VOC Sensor Air Quality Sensor High sensitivity to VOCs and odorous gas

Description

The sensing element is comprised of a metal oxide semiconductor layer formed
on the alumina substrate of a sensing chip together with an integrated heater.
In the presence of detectable gas, sensor conductivity increases depending on
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.
The TGS 2602 has high sensitivity to low concentrations of odorous gases
such as ammonia and H2S generated from waste materials in office and home
environments. The sensor also has high sensitivity to low concentrations of
VOCs such as toluene emitted from wood finishing and construction products.
Due to miniaturization of the sensing chip, TGS 2602 requires a heater current
of only 56mA and the device is housed in a standard TO-5 package.
