Gun4ir project uses the wiimote sensor. However it uses multiple ir sources than the single "sensor bar" of the wii. It's just that the company who makes the sensor, Pixart seem very unfriendly to hobbyists. Hell even buying the sensor from say https://uk.robotshop.com/products/ir-tracking-camera now links to PDFs with some "sample code" but no actual real datasheet (because of Pixart NDA). Which is funny because only a short while ago everyone was linking to a wiimote hacking wiki.
There are no officially available docs for this part - afaik the part was specifically made/manufactured for Nintendo and there does not seem to be an option to get the original datasheet even if you're willing to sign an NDA.
They do have newer sensors in the same range though, that are capable of tracking even more points.
