IR Reflective Sensor 10cm
This IR proximity sensor can detect opaque objects within 10cm and connects to an Analog Input or VINT Hub port.
This sensor can detect the presence of objects at a distance of 0 to 10cm regardless of the object reflective properties. When an object enters the range of detection, the output voltage becomes zero, and when it leaves, it returns to 5V. The 1103 works just as well in both dim and well lit environments.
The sensor cannot detect the presence of the object if it is emitting large amounts of light, such as a light bulb.
