ماژول سنسور تشخیص گاز دی اکسید کربن MH-Z19B

Description:

MH-Z19 Carbon dioxide gas sensor (hereinafter referred to as sensor) is a general-purpose, small sensor that uses non-dispersive infrared (NDIR) principle to detect CO 2 present in air. It has good selectivity, no oxygen dependence, and long life. long. Built-in temperature compensation; both digital output and waveform output for easy use. The infrared sensor is a high-performance sensor that combines sophisticated infrared absorption gas detection technology with precise optical path design and sophisticated circuit design.
