[1] The time from when the sensor is powered on to when the data is read. Note the parameter when the sensor is powered on. [2] If started in an environment with clean air it requires less time [3] The measurement data update interval, after the power-up warm-up time, if the power supply continues, the sensor periodically updates the reading at this interval.
