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 p… ...

He measures the sensor with the ADC on an ATmega16 microcontroller. Running at 16 MHz he can sample each of the eight analog-to-digital converter channels at 1202 Hz.

Research & Development Optical coating approach prevents fogging and unwanted reflections 19 Jan 2023 Technology helps sensor and camera systems perform optimally by keeping optics transparent.

When there are extreme temperature differences between the environment and the measuring system, fogging sometimes occurs on the optical surfaces, impairing functionality. Gärtner’s team collaborated ...
