The sensor has an output of half supply voltage (2.5V) at zero magnetic field with a sensitivity of 1.3mV/Gauss. This makes it suitable for connection to the XO1.5 (input range 0.17 - 3.3V). For the XO1.0 (input range 0.4 - 1.85V ) a 2:1 voltage divider is necessary. | The sensor has an output of half supply voltage (2.5V) at zero magnetic field with a sensitivity of 1.3mV/Gauss.
