MH-Z19C 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
Therefore, the XENSIV TM PAS CO2 sensor outperforms state-of-the-art NDIR sensors in terms of size and cost, without compromising on performance. Features. Benefits. Exceptionally small form factor (14 x x mm 3) Accurate and robust performance at ppm level (±30 ppm ±3% of reading) SMD package delivered in tape and reel.
