Description

MH-Z19B NDIR CO2 Gas Sensor Module

MH-Z19B NDIR infrared Carbon dioxide gas module

MH-Z19B is a very easy to use Carbon dioxide (CO2) gas sensor module it is used for Air quality Control. It has UART and PWM output so it can directly interfaced to Raspberry pi, Arduino and various other Micro-controllers.

MH-Z19B NDIR infrared gas Sensor 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.

We have Various sizes of Gas Sensor Check out our complete collection of Gas Sensor.

If you are in Nashik you can buy this Electronic Component at our local shop at New CBS, Nashik or you can place order online and get it delivered at your doorstep anywhere in India.
