- • Target gas: Carbon Dioxide
- • Range: CO2(400-2000ppm/400-5000ppm)
- • Application: HVAC,building ventilation system, indoor air quality monitoring system
- Principle Introduction:
MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 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.
