MH-Z19B 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 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.

Applications:

• HVAC refrigeration
• Air cleaner device
• Indoor air quality monitoring
• Smart home
• Ventilation system
• School

Features:

• Chamber is gold plated, water-proof and anti-corrosion
• 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

Package Includes:

1 x Winsen MH-Z19B NDIR CO2
