I came across a bunch of cheap little modules of what appear to be a great UV light sensor for Arduino projects. If you go online and look you can see that these modules are based on the GUVA-S12SD ...

[Akiba] at Hackerfarm has come up with the NukeMeter, a meter that measures the output of their UV-C sterilizer the NukeBox. It is built around a $2.50 sensor and a $3 Arduino. The NukeMeter is ...

The LTR-390, in contrast, does have a real light sensor in the UV spectrum. It’s also got a much much simpler I2C interface so you can run it on the Arduino or Python microcontrollers ...

This UV sensor identifies the presence of grease, glue, labels, wood, thread, rubber, paint, UV ink, UV crayon, and more to confirm manufacturing processes more reliably than vision systems.

The new UV light sensor technology, developed by the research team led by Professor Shigetoshi Sugawa and Associate Professor Rihito Kuroda at Tohoku University's Graduate School of Engineering ...

Powered by an Arduino, the clock uses an articulated arm with a UV LED to write out the current time on a piece of glow-in-the-dark material. The time doesn’t stay up for long depending on the ...
