Household Combustible Gas AlarmProduct characteristics:
Ultra-low power consumptionDescription
TX711-A70 Combustible Gas Sensor (hereinafter referred to as "the Sensor") is a compact, general-purpose sensor that utilizes the Non-Dispersive Infrared (NDIR) principle to detect combustible gases present in the air. It features excellent selectivity, is independent of oxygen concentration, offers a long service life, incorporates built-in temperature compensation, and utilizes a digital output for ease of use. This high-performance sensor is manufactured by seamlessly integrating mature infrared absorption gas detection technology with precision optical and circuit designs.
