Infrared Carbon Dioxide Sensor

Features:

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.
