Product Description

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
