Pzsmocn ITR9608 Photo Sensor Compatible with Raspberry Pi/Arduino Board. for Copier, Printer, Facsimile, Ticket Vending Machine, Opto-Electronic Switch, Motor Speed Detection, Pulse Counter.

Well put together, nice plastic case to protect it. This is one of those little gizmos I thought would be handy to use with our ream of Raspberry Pi that my husband has doing assorted jobs. This is going to take some play time, there were no instructions but the website and the bit of reviews I read suggested use with the printers and that more than likely is how we will be using it. I see no reason that this wont work, all solders look good on the bits, I would have just appreciated some guidance in the form of some sort of manual.

Well put together. I appreciate the plastic case that it comes with to protect it. It has an LED to show power and another for signal. Operation is easy, and there is a URL for the data sheet too. Overall, very pleased!
