The MH-Z19E utilizes mature NDIR technology to detect carbon dioxide concentrations in ambient air. This method provides excellent selectivity for CO2, is non-oxygen dependent, and ensures a stable, linear output over the sensor’s extended lifespan. The module integrates a precision infrared optical path and signal conditioning circuitry into a compact form factor.
It is engineered for reliable performance in indoor environmental monitoring applications. The built-in temperature compensation algorithm enhances accuracy, while the robust design offers resistance to interference from humidity and common airborne contaminants, making it suitable for continuous operation in residential and commercial settings.
