White surfaces reflect more light than black, so, when directed towards a white surface, the capacitor will discharge faster than it would when pointed towards a black surface. The power input and output pins are brought out to a 3-pin, 0.1" pitch header. The board also has a single mounting hole if you want to screw it onto something. 5VDC operating voltage 25mA supply current Digital I/O compatible No ADC required Optimal sensing distance: 0.125" (3mm) 0.3x0.55" Package include: 5 x sensor module 5x pin
