Description

GMH-Z19D NDIR infrared CO2 sensor module is a common type, small size sensor, pins type or terminal type, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air,  with good selectivity, non-oxygen dependent and long lif e. Builtin 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

*Good stability

*Temperature compensation, excellent linear output

*Multiple output modes: UART, PWM

*Long lifespan

*Anti-water vapor interference, anti-poisoning
