Sight across the land or sea to a known set of targets and decide which is the smallest you can still recognize.
Good day everyone. Can anyone Pls help me with an idea on how to design a dust sensor. Maybe using LDR or any other means.
Diagrams will be highly appreciated.
Thank you in advance.
thank you GopherT but the dust sensor is for a flat surface like table not air.
You need to determine what attributes can be used to differentiate between a dusty surface and a clean one. I imagine diffraction of reflected light would be higher for dusty surfaces, but you'd need base line (clean surface) diffraction values to compare against, and those would probably vary quite a lot for different surfaces.Thank you guys. The intention of this is to design the sensor myself and not to use an already designed module. The sensor will monitor the dust on a flat surface like "Table"
Hey thats what my wife is forThe sensor will monitor the dust on a flat surface like "Table"
Dust reflects light so an optical sensor should work: pump air through a dark chamber; shine a beam of light into the air and see how much is reflected back.Can anyone Pls help me with an idea on how to design a dust sensor.
