I am purchasing sensors for a project and this may be a very obvious question but I want to ensure my theory is correct before I buy anything.
I have a colour sensor which only detects the light that is entering the sensor and I need a laser which will emit a beam of light that will reflect off of a red surface.
To do this I am planning on buying a red laser which will reflect off of a red tape and enter the colour sensor to indicate the colour red is above. Is this possible with the equipment I've mentioned above?
The distance between the tape and sensor is about 600mm.
