Product Description:

TGS2602 - for the detection of Air Contaminants

Features
* High sensitivity to VOCs and odorous gases
* Low power consumption
* High sensitivity to gaseous air contaminants
* Long life
* Uses simple electrical circuit
* Small size
Applications
* Air cleaners
* Ventilation control
* Air quality monitors
* VOC monitors
* Odor monitors
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 TGS2602 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, TGS2602 requires a heater current of only 56mA and the device is housed in a standard TO-5 package.
