Rotation speed sensor for Tank Chassis

thingiverse

PID for tank chassis. Drive sprocket has additional holes to secure two 2mm neodymium magnets firmly in place. The servo mount now comes equipped with a separate mounting point specifically designed to hold a hall sensor at the precise angle needed to maximize efficiency. Every time a magnet aligns perfectly with the hall sensor, the resulting magnetic field causes the output of the hall sensor to plummet instantly. I am presently calculating pulses over a set timeframe in order to fine-tune the left and right motor speeds for flawless execution and crisp turns. Furthermore, this precise measurement enables effortless accurate turns, as the sensor can accurately detect the number of pulses. **Assembly Instructions** Print the servo mounts and two drive sprockets precisely as designed without modification or alteration. Magnets should be exactly 2mm x 2mm Neodyms with a sturdy construction that fits securely in place via push-fit technology. Please ensure that you have positioned the magnets correctly in terms of their orientation (N/S) to match the specific hall sensor requirements of your setup. For best results, mount the hall sensor directly onto an .8mm circuit board to ensure reliable connections and functionality. When using a hall sensor that is overly sensitive, you may encounter instances where it fails to register changes as magnets move past it; adjust sensitivity levels accordingly to achieve optimal performance with every print job, regardless of the printing settings utilized.
