ow Power Consumption Figaro MEMS Semiconductor Air Quality Gas
---Worlds smallest gas sensor class
The sensing element is comprised of a sensing chip and an
integrated heater formed on a silicon substrate using MEMS technology, and a metal-oxide semiconductor layer formed on the sensing chip.
The device is housed in a surface-mount ceramic package. Due to
miniaturization of the sensing chip,TGS 8100 requires a heater
power consumption of only 15mW, and is suitable for low-power
equipment and battery-operated instruments.
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 8100 has high sensitivity to low concentrations of gaseous
air contaminants such as cigarette smoke and cooking odors.
By utilizing the change ratio of sensor resistance from the
resistance in clean air as relative response, human perception of
air contaminants can be simulated and practical air quality control
can be achieved.
