I would like to use Arduino to detect the magnetic field of different magnetic pads. To do this, I've bought a 1108 Phidget sensor which has a voltage output proportional to the applied magnetic field.
I've bought also three magnetic pads with different size and force (200g, 300g and 400g).
I connected +5V and GND and the voltage output directly to A0 analog input in my Arduino UNO but the sensor readings are not so accurate because I can't recognize the magnetic field of each magnets but only their presence.
I was looking for the senso suggested also in the Arduino playground: A1301. Do you think it will be suitable for my application?
I just want to be able to recognize at maximum 6 different magnetic pads without errors.
Thank you a lot!
