Product Description

High sensitivity Small size and Long life time Air Contaminants Sensor-TGS***0
 

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.

The TGS ***0 has high sensitivity to low concentrations of gaseous air contaminants such as hydrogen and carbon monoxide which exist in cigarette smoke. The sensor can detect hydrogen at a level of several ppm.

Due to miniaturization of the sensing chip, TGS ***0 requires a heater current of only *2mA and the device is housed in a standard TO*5 package.

Below the advantages of the oxygen sensor:

* Low power consumption
* High sensitivity to gaseous air
contaminants
* Long life and low cost
* Uses simple electrical circuit
