[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] When the light intensity is greater than 150 Lux, the warm-up time of the value (@typical 300ms) can
ensure 100% reading of the correct data. When the light intensity is less than 150 Lux, the warm-up time
of the value (@max 1000ms) can ensure 100% reading of the correct data.
