Manufacturer's page of the muRata SCA3300. There are also good companies that give good information and won't let you down, such as: Adafruit, Sparkfun, Pololu. There are companies that started cheap but aim for better quality, such as Elecrow. Some sellers tell anything to sell something. Sometimes a factory rejects a batch, and those might show up on those websites. They sell cheap things that can have counterfeit components, low quality, not certified things, stupidly exaggerated accuracy numbers, and so on. We have websites that sell cheap things, such as: Amazon / Ebay / AliExpress. Hi, this is planet Earth you have landed on. I am curious on what everyone thinks on the 2 sensors I mentioned above. i know that would give the best accuracy of all but the effort is not worth it, if even possible physically. There is no place to easily mount a mechanical encoder setup. My thought was that this sensor could just simply be epoxied in place. The sensors would need to be calibrated to establish 90° vertical (perpendicular to table top) and 0.000" blade height but that is easy to do. I would need to do a little math to compensate slightly for the geometry error on the height but it is minor, around. I would mount the dual axis sensor on the arm that moves and can capture both angular movements. What I am looking to do is put this on a table saw to measure the tilt of the blade and the height of the blade. If what it says, 0.05° accuracy, is correct, then that one would work also. WT901BLECL MPU9250 High-Precision 9-axis Gyroscope+Angle(XY 0.05° Accuracy)+Magnetometer with Kalman Filter, Low-Power 3-axis AHRS IMU Sensor for Arduino. These multifunction chips talk in g's and with a equation get back to a angle. I came across the SCA3300, It says it is accurate to 0.0035° but I am not sure that is the accuracy of what I am thinking.
