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.
What else?
Any help you can give would be greatly appreciated..
