When powered on, the probe starts up within 20 seconds. Measurements from the outputs (digital and analog) become available during this time but note that they will only reach specified accuracy after a 4-minute warm-up period. For this reason, you should design your system so that it does not rely on measurements from the probe during this time.

Specifically note that the CO2 reading will rise to the correct reading as the sensor’s infrared emitter achieves operation temperature.
