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 IIC 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
*Good stability and consistency
*Temperature compensation, excellent linear output
*Multiple output modes: UART, IIC, PWM
*Long lifespan
*Anti-water vapor interference, anti-poisoning

Applications：
*HVAC system *Air purifier
*Indoor air quality monitor *Smart home device
*Consumer CO2 meter
