Gravity I2C Waterproof Ambient Light Sensor Temperature Compensation

Recently purchased (not yet received) the Gravity Waterproof Ambient Light Sensor.  Specs state operating temperature is -40 to 85°C/-40 to 185℉.


Question is: Is this device in fact TEMPERATURE COMPENSATED over this temp range?  Or does the spec merely mean the device will not be physically damaged?

OK, I'll buy that logic.  I didn't know one way or another whether there was a temp sensor buried inside.  


The DFRobot web site says, “the sensor features an IP68 waterproof rating, which means it can be fully immersed in water without suffering any damage. This makes it perfect for outdoor projects that require reliable light measurement in harsh environments”.


Photoresistors, photodiodes, and phototransistors are ALL temperature sensitive.  I assume the light sensor is one of these.


I need to use this light sensor OUTDOORS (summer thru winter).  


Is the output sensitive to extreme temperature changes of not ??

Since there is not temperature sensor on this board. So the sensor doesn't have the temperature compensation.
