MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output. MH Z19B is developed by the tight integration of mature infrared absorbing gas detection technology, precision optical circuit design and superior circuit design.
