BTT SFS V1.0 Smart Filament Sensor Detection Stuck Blocking Filament Module

I installed and tested this sensor with Octoprint running on a Raspberry Pi and it works great. Since the Octoprint software ignores the built in filament sensors for many printers, this sensor was a great way around that problem. Since it also detects tangles and full clogs, it really is an excellent sensor for those using Octoprint. The video attached details the wiring and installation for a setup running Octoprint on a RPi4

It has made such a great difference in my being able to focus on other things while printing. Before having this sensor I always felt like I had to watch dog my printers. Now I can get other things done while the printers are doing their thing.
