Product Introduction
1. Japan Figaro Methane Carbon Monoxide Sensor (CH4/CO Sensor)TGS3870Description:
TGS3870-B00 is a micro-bead type sensor used for detecting methane and carbon monoxide.Semiconductor gas sensorDue to the micro-bead type gas sensing structure, by applying periodically varying high and low voltages to the sensor's heater, a single sensor can detect both methane and carbon monoxide gases. Moreover, the gas sensing element is extremely small, and the heater's power consumption is only 38mW (average).
TGS3870-B00 has extremely low sensitivity to ethanol vapor, a typical interfering gas in residential environments, and is highly durable, making it the most ideal sensor for the gas alarm market.
2. Japan Figaro Methane Carbon Monoxide Sensor (CH4/CO Sensor) TGS3870Features:
* Small size, low power consumption* Good selectivity and high sensitivity to methane and carbon monoxide
* Low sensitivity to ethanol vapor
* Long lifespan and low cost
* Methane and Carbon Monoxide Composite Alarm
