MH-Z19C Infrared Co2 Sensor for Co2 Monitor MH-Z19C Infrared Carbon Dioxide Co2 Gas Sensor 400-5000Pp

MH-Z19C 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.
