The gas chamber is gold-plated, waterproof and anti-High sensitivity, low power consumption;Excellent stabilityTemperature compensation, excellent linear outputProvide serial port (UART), analog (), PWM waveform and other output methodsLong service life;Anti-water vapor interference, no poisoning-Z14 carbon dioxide gas sensor (hereinafter referred to as the sensor) is a general intelligent small sensor that uses the principle of non-dispersive infrared (NDIR) to detect CO2 in the air. It has good selectivity and no oxygen dependence, and has a . Built-in temperature compensation; it also has digital output, analog output and PWM output, which is easy to use. This sensor is a high-performance sensor that closely combines infrared absorption gas detection technology with precise optical path design and excellent circuit design.Colour:As ShownMaterial:PCBstyle:-Z14ATips: The product may be updated constantly ,Due To Different Batches, The Actual Product May Have Slight Differences Or Color Differences, Which Does Not Affect UsePackage Contents:1 * NDIR CO2 SENSOROnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
