Product introduction: The MH-Z19E Carbon Dioxide Gas Sensor (hereinafter referred to as the sensor) is a general-purpose intelligent compact sensor. It is available in both pin and terminal versions and uses the Non-Dispersive Infrared (NDIR) principle to detect C02 in the air. It is characterised by good selectivity, no oxygen dependence and long life.
Built-in temperature compensation: at the same time with serial output, PWM output, easy to use. The sensor is the mature infrared absorption gas detection technology and precision optical circuit design. The sensor is a high-performance sensor made by closely combining the mature infrared absorption gas detection technology with precise optical circuit design and excellent circuit design.
Sensor characteristics: High sensitivity, low power consumption Excellent stability temperature compensation, excellent linear output Provide serial port (UARD, PWM waveform and other output methods Long service life Resistant to water vapour interference, non-poisoning
Main Applications: Air quality monitoring equipment HVACR equipment air purification equipment Intelligent home Fresh air system Schools
