QC102 NDIR infrared carbon dioxide sensor is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output. It is developed by the tight integration of mature infrared absorbing gas sensor alarm technology, precision optical circuit design, and superior circuit design.
