ماژول سنسور دی اکسید کربن مادون قرمز MH-Z14A NDIR

MH-Z14A NDIR Infrared gas module 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 sensor can do temperature compensation; and it has digital output, analog voltage output and PWM output. This common type infrared gas sensor is developed by the tight integration of mature infrared absorbing gas detection technology, Precision optical circuit design and superior circuit design.
This product adopts infrared light source and dual channel thermopile detector to process the measurement and reference signals, and to compensate the temperature. Even under the harsh temperature and environmental conditions, it can also obtain stable and reliable measurement results. It has nice selectivity, high sensitivity, no oxygen dependence and long life.

Infrared carbon dioxide sensor, using NDIR infrared absorption detection principle, no oxygen dependence.

High sensitivity, quick response and high resolution.

Support a variety of output forms, outstanding linear output.
