NDIR gas alert gas sensor

NDIR gas alert gas sensor

1. NDIR Measurement Principle. NDIR CO 2 sensor uses the principle that the gas to be measured absorbs infrared rays in a specific wavelength range, and the degree of absorption depends on the concentration. NDIR is an abbreviation for Non-Dispersive InfraRed. Infrared rays emitted from the light source are measured by an infrared detector after passing through the gas.
