19. D6 CO
2
sensor FYAD00-CO2
Sensor FYAD00-CO2 measures CO
2
concentrations from 0 to 10000 ppm; it uses a 2-
beam infra-red cell. Measured CO
2
values are affected by atmospheric pressure; an in-
tegrated atmospheric pressure sensor performs the necessary compensation. A delay
of 180 seconds is required after sleep mode before a reliable average value can be ob-
tained.
