QTRX-HD-04A Reflectance Sensor Array: 4-Channel, 4mm Pitch, Analog Output, Low Current POL_Connectors This output can supply up

This output can supply up to 5 mA to external loads

600 and 650nm of light each with 40nm of full-width half-max detection

you'll get very weird results

But if you want to add even more

It operates from 2. 9 V to 5. 5 V and offers dimmable brightness control independent of the supply voltage. In general, the closer the object, the higher the contrast between light and dark readings, but high
