QTRX-MD-07A Reflectance Sensor Array: 7-Channel, 8mm Pitch, Analog Output, Low Current Boson Kits * 1x 2K resistor

* 1x 2K resistor

Each channel of the module is independent

But you will need additional corresponding Grove shield board such as Grove - Base shield v2

RST / MS Input pin that can be used to reset the board or trigger a new sample

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
