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.
