MH-Z1911A Infrared CO2 Sensor Intelligent Sensor With Small Size HVAC System Air Purifier Consumer CO2 Meter Indoor Environmental Control

Profile:

MH-Z1911A infrared CO2 sensor is intelligent sensor as shown in Figure 1,common type, small size, 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.

Features:

*High sensitivity, low power consumption
