TGS3870-B00 Carbon Monoxide Gas Sensor

Tgs3870-b00 gas sensor for the detection of both methane and carbon monoxide
features:
* miniature size and low power consumption
* high sensitivity and selectivity to both methane and carbon monoxide (co)
* low sensitivity to alcohol vapor
* long life and low cost
applications:
* combination methane and carbon monoxide detectors
tgs3870-b00 is a micro-bead type semiconductor gas sensor for the detection of both methane and carbon monoxide. Using a micro-bead gas sensing structure, both methane and carbon monoxide can be detected with a single sensor element by periodic application of two different heater voltages (high and low). Miniaturization of the gas sensing bead results in a heater power consumption of only 38mw (average).
tgs3870-b00 has low sensitivity to alcohol vapors (a typical interference gas in the residential environment) and has high durability, making the sensor ideal for consumer market gas alarms.
