Find out how fresh the air in a room really is. The MH-Z19B measures carbon dioxide using infrared (NDIR) sensing, giving steadier readings than low-cost chemical sensors.

Why you will like it

• NDIR infrared sensing – stable, repeatable CO2 readings.
• UART and PWM outputs – choose the interface that suits your controller.
• Built for indoor air quality – know when a room needs ventilation.
• Works with Arduino and ESP boards – well supported by libraries.

Ideal for: air quality monitors, classroom and office CO2 displays, and ventilation control.
