This sensor detects obstacles in the range from 0.2 cm to 60 cm. It is equipped with an analog signal output, so when there is no obstacle at the OUT output, the voltage reaches 3V, and the closer the obstacle is, the voltage drops (not linearly) to 0.06V. This is a reflective IR optical sensor and may not respond properly to black. The sensor works on a power supply from 3.3V to 5V.
