 ## Position estimation with the integrated linear hall sensors
 
 ### 1. Setup
-Each motor is composed of two ratiometric linear hall sensors. (Texas Instrument DRV5053 Analog-Bipolar Hall Effect Sensor) They are placed at around 120º from each other (eyes measured) and measure the magnetic field of the rotor.

-Ratiometric means that the output signal is proportional to the voltage supply to the sensor. In this setup, with 5V supply, the output measured is between 520mV and 1.5V, so a 1V amplitude signal. 
+Those sensor are absolute, meaning that the output of the measured magnetic field is the same regardless of the power suplly. In this setup, with 5V supply, the output measured is between 520mV and 1.5V, so a 1V amplitude signal.
