MH-Z19B carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general-purpose
smart small-scale sensor that uses non-dispersive infrared (NDIR) principle to detect the
presence of CO2 in the air, with good selectivity and anaerobic Gas dependence, long life
and other characteristics; built-in temperature compensation; at the same time with serial
output, analog output and PWM output, easy to use. The sensor is a high-performance sensor
that combines mature infrared absorption gas detection technology with precise optical path
design and sophisticated circuit design.
