A third Hall effect sensor is used to measure a throttle stick positioned on the side of the box. An Arduino micro reads the sensors and converts the analog signal to USB.

Picked at random: The SiLabs Si7210 [1] is a Hall effect magnetic sensors with 0.1% linearity and an I2C interface, no Arduino ADC to tame. The Si7210 tops out at 0.2T. Eval bords for the series ...
