Tips/Techniques
Sick Sensors Transistor Output
Some of these sensors (I've used the IR ones) require boosting via a transistor to get 5V output. They don't output 5V on their own (although if memory serves me there is some hack you can do to read the direct output without any transistor if you have a micro/arduino. I think it's something to do with reading it via an Analog pin. I'd have to check my code. https://www.eevblog.com/forum/beginners/any-help-raspberry-pi-prod-counter-w-reflective-sensors-output-concerns/msg5449463/ Example of data sheet here (note that the switching (digital output in newer data sheets) output is push/pull : http://web.archive.org/web/20190415090838/https://cdn.sick.com/media/pdf/6/56/756/dataSheet_WSE16P-24162100A00_1088329_en.pdf These can be expensive new. Look on the surplus market.
