The interesting thing is, he built these optical flex sensors himself. He likes to say that this is a ghetto fiber-optic setup. The inlaid diagram above gives you an idea of how the sensors work.

Wanting to experiment with using optical mouse sensors but a bit frustrated with the lack of options, [Tom Wiggins] rolled his own breakout board for the ADNS 3050 optical mouse sensor and in the ...

sensor, the transducer signal is more robust and stable than that of an optical system. The transducer integrates both the magnetic technology and the speed measurement sensor, which saves space ...

"Our spark-free optical-based hydrogen sensors detect the presence of hydrogen without electronics, making the process much safer." Not just for cars Hydrogen power has many more applications than ...
