“the extra temp sensor doesn't appear to give valid readings, but the magnetic sensor seems ok. I have two connected to my robot, one on the base and one on the head, but the angles don't match. I saw a comment about floating pin when the address pad is cut. is that still the case?. This sensor is fast and once I wrote a lib for the mag part gives a compass of moderate accuracy. probably needs more work on my lib, but the python lib provided gives the gauss values and is easy enough to use.”
“Accelerometer works well and fairly consistently for detecting orientation; I’ve not used it for actual movement sensing just the “which direction is gravity pulling me?”
Compass is not great; it’s moderately accurate around North but then is wildly off for most of the rest of it. East claims to be about 60° not 90, South is about 110° not 180, and then on the West trip back to North it gallops to make up for lost time. Depends what you want to use it for; I’m wanting to align a telescope to North so actually it’s not so bad, but if you wanted to use it for other directions you’d probably have to do some calibration and write out some lookup tables for your code to correct the output with.”
