IAQ Smart home Air quality HVAC Use CO2 Carbon Dioxide Sensors, NDIR Infrared Improved Accuracy
Recommended Modules: MH-Z19C, MH-Z19E, pins type or terminal type optional
Winsen developed these CO2 sensor modules with 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 detection technology, precision optical circuit design and superior circuit design.
