this is my first post.
we are planing to make a new dust sensor. This sensor should detect when the dust is accumulated over a surface. when the accumulated dust become noticeable, the sensor output will be high. the proposed sensor may use the light , IR or color sensing. it should record the readings of the reflected IR (or color) when the surface is clean. after dust accumulation over the surface,the sensor measurement will be somehow different. this difference will trigger the sensor decision control to activate the output. this sensor is expected to be helpful in automatic cleaning robots. to make the cleaning schedule adaptive depends on the weather and not fixed schedule.
i searched the net and could not find any similar ideas.
any comments, suggestions, similar ideas or discussion will be helpful.
