A rugged stainless steel sensor is a popular choice and in some applications a sensor made with food grade materials may be required.
Light sensor steel marbl e reading.
This one shows the response of a max44009 ambient light sensor.
Brainstorm idea first the marbles will be placed into the hopper which will feed the marbles into a backward slant.
The meter reading in lux.
When the light sensor got a reading it would send the conveyor either left or right.
The entire infrared component is radiated back and no incident light is being reflected.
Sensors rated ip69k are ideal for these environments as they have been tested to ensure reliable operation even when subjected to frequent cleaning.
Included are four channels for a quick and easy way to add vernier sensors without external wiring or signal conditioning.
Plan 1 was to have a giant funnel at the top of the machine and you would drop the marble into it.
Learn more about ip ratings and what they mean.
However i realized this design would have many difficulties in the building and coding.
Line follower releases new marble via servo powered lever a when marble is detected 5.
A motor will start to rotate and cause a rod to push the marble up the backward slant and onto another slant that is slanted downward the marble will then go down both slants and stop at a gate when it stops a line follower or light sensor will activate and detect what color.
The sensordaq interface is perfect for teaching ni labview or for building sensor control student projects using ni labview software.
Data sheets for most ambient light sensors include a graph of typical light sensitivity vs.
After this a magnet would drop down picking up the steel marbles and moving them to a container.
Light sensor detects shade color of marble triggering conveyer belt 3.
The marbles would then be dispensed onto the conveyor belt which would move the marble underneath the light sensor.
Conveyer belt moves according to light sensor reading to make the marble go in the correct container.
The clear would go to the other side into a bin.
Dynamic range of light measurements the human eye is sensitive to a wide range of light conditions.
Wood and steel would go to one side of the conveyor belt and a magnet would seperate the steel from the wood.
All light falling onto the black body incident light is absorbed by the black body.
Then a platform would catch marbles.
Once the light sensor got a reading from the marble the 3 arm marble catch which consisted of 3 poles with buckets at the end extending from a motor would move to one of three positions the correct bin for the colored marble.
Our psuedo code is at the bottom right.
Emissivity is also closely related to absorption and reflection of light.
After that a light would shine on the marbles witch would give a reading through light sensor.
Materials that are not perfect emitters reflect a portion of incident light.
