== Hall Effect Sensor ==

−

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.
