− | A Hall Effect sensor such as the (Allegro) UGN3503UA Hall Effect Sensor http://www.jaycar.com.au/products_uploaded/ZD1902.pdf ($6ea.) can be used to measure magnetic fields. (The Allegro1302 http://www.alldatasheet.com/datasheet-pdf/pdf/120806/ALLEGRO/A1302EUA.html is an alternative to the Allegro3503).

− | 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.
| + | El sensor tiene una salida de media tensión de alimentación (2.5V) a cero el campo magnético con una sensibilidad de 1.3mV/Gauss. Esto hace que sea conveniente para la conexión a la XO1.5 (rango de entrada de 0,17 - 3,3). Para el XO1.0 (rango de entrada 0,4 - 1.85V) un divisor de tensión 2:1 es necesario. |
