Proximity sensors are common enough in automation ... The first try at this used an OBP732 reflective transmitter and an ATtiny202 microcontroller and had three pads on the PCB for programming.

[Sebastian Steppeler] has been hard at work on his optical sensors for an electric piano. When we looked in on the project back in October he was testing reflective sensors to increase ...

Both sensors easily recognized the specially formulated, TiO 2-based paint but did not readily detect the traditional paint. The researchers say that their highly reflective material could help ...

researchers revealed the development of highly reflective black paint, utilizing titanium dioxide, to enhance the visibility of dark objects for autonomous vehicles equipped with lidar sensors ...
