Detect transparent and dark objects with blue light

Detection of transparent and dark objects can be a difficult challenge. Because of reflection, dark and transparent objects are hard to detect. In practice a sensor recognise two objects instead of one. This is because of the reflection of an object. Black objects absorb almost all the light. This makes it difficult for the sensor to recognise an object. SensoPart blue light offers the solution!

Red and blue light sensors

Where conventional red light sensors reach the limit, SensoPart's Blue Light sensor offers the solution. Instead of a standard red light point, a blue light point is used. Because of the blue light point, the sensor is able to recognize transparent and dark objects.
