Product description MH-Z19 carbon dioxide gas sensor (hereinafter referred to as the sensor) is a generic type, small sensors, using non dispersive 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, easy to use. The sensor is a high performance sensor which is combined with the mature infrared absorption gas detection technology and the precise optical path design and the 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. Technical index Product model MH-Z19 Detecting gas carbon dioxide Operating voltage 3.6 ~ 5.5 DC V Average current less than 18 mA Interface level 3.3 V Measurement range of 0 ~ 0.5% Vol range of optional Output signal UART PWM Preheat time 3 min Response time T90 < 60 s Operating temperature 0 ~ 50
