Product Description:

TGS3870 Methane Carbon Monoxide Sensor (CH4/CO sensor) For Gas Alarm

Features:

figaro methane carbon monoxide sensor (CH4/CO sensor) TGS3870

The TGS3870-B00 is a microbead semiconductor gas sensor for the detection of methane and carbon monoxide. Due to the use of a microbead gas sensing structure, through the heating of the sensor

By applying a periodically varying high and low voltage, a sensor can detect both methane and carbon monoxide. Also, the gas sensing body is very small

Small, heater power consumption only 38mW (average).

The TGS3870-B00 is extremely durable due to its low sensitivity to ethanol vapor, a typical disturbing gas in residential environments, making it the ideal sensor for the gas alarm market.

Two, Japan figaro methane carbon monoxide sensor (CH4/CO sensor) TGS3870 features:

* Small size, low power consumption

* Good selectivity and sensitivity to methane and carbon monoxide

* Low sensitivity to ethanol vapor

* Long service life, low cost

Third, methane carbon monoxide sensor (CH4/CO sensor) TGS3870 application:

* Methane, carbon monoxide composite alarm

Four, methane carbon monoxide sensor (CH4/CO sensor) TGS3870 sensitivity characteristics (methane) :

The figure below shows a representative sensitivity characteristic curve measured under standard test conditions (see back).

The ordinate represents the sensor resistance ratio Rs/Ro, and the definition of Rs and Ro is as follows:

Rs = Resistance value of the sensor in various concentrations of gas

Ro = Resistance value of the sensor at 3000ppm methane
