Technical specifications of the Gravity Grayscale sensor SKU:DFR0022

Hi, are there any other technical datasheets available besides the one that is listed on the DFRobot Wiki page? i am trying to implement this sensor in a prototype that requires it to be switched on at all times. May I know what is the lifespan of this sensor, and other information such as the operating limits of this sensor in terms of temperature, and any other conditions that may possibly affect the electronics within the sensor? I tried to look for those specifications but it was not mentioned in the datasheet on the Wiki page.
