MH-Z19B Co2 10000ppm Sensor Module
MH-Z19B overview
This 10000ppm MH-Z19B co2 Sensor detects carbon dioxide Co2. 10000ppm MH-Z19B CO2 sensor has high sensitivity, high resolution, and low power consumption. MH-Z19 carbon dioxide gas sensor (hereinafter referred to as the sensor) is a generic type, small sensor, using the nondispersive infrared (NDIR) principle to detect the air in the presence of CO2, with good selectivity and no oxygen dependence and long service life. Built-in temperature compensation, with digital output and waveform output, is easy to use. The sensor is a high-performance sensor that is combined with mature infrared absorption gas detection technology and precise optical path design and excellent circuit design. Sensor characteristics High sensitivity, high resolution, low power consumption Provide UART, PWM waveform, such as a variety of output mode Temperature compensation, excellent linear output Excellent stability Long service life Anti-water vapor interference, not poisoning Main application Can be widely used in HVAC refrigeration and indoor air quality monitoring.
