MH-Z19B NDIR high-resolution CO2 sensor on UART PWM

In response to the growing demand for air quality monitoring, we offer the advanced CO2 MH-Z19B sensor module. This high-resolution sensor allows precise and stable measurement of carbon dioxide concentration in the air, using the proven NDIR method (non-dispersive infrared sensor). This method ensures the reliability and accuracy of the measurements. The MH-Z19B sensor features a number of advantages that make it an extremely effective tool in environmental monitoring:

* High sensitivity and resolution enable accurate readings,

* Low power consumption increases its energy efficiency,

* Three measurement reading modes adapt the device to different user needs,

* Temperature compensation and perfect linearity of measurement ensure consistent precision,

* Long life guarantees reliability for years.
