MH-Z19B Gas CO2 Sensors NDIR PIN Connected Analog And PWM Output
The MH-Z19B carbon dioxide gas sensor (infrared CO2 sensor) is a general-purpose smart small sensor that uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air, with good selectivity, no oxygen dependence, and long life. Built-in temperature compensation; also has 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.
