Would you please help me with this question.. Q: The benefits of removal of dirt and grime around optical sensors?
I can say: 1/ If there is too much dust, it will break down and by keeping it clean the sensor will live longer. 2/ Higher sensitivity to light, and more reliable. 3/ If it damaged or broke down, it would probably cost you to replace your device or the whole system and to save your time as well. 4/ Ensuring high accuracy of data, and more efficient.
Any help you can give would be greatly appreciated..
