First Post. I will be designing a magnetometer over the next few weeks and was looking for some guidance.
I plan on using a Arduino board to give it a few features. Power readings from electronics is one of the main features (which will be a rough estimate).
Where to start with a sensor is where I am lost. I would like to use a hall sensor. I blindly ordered some and realized that was a mistake as I didnt really understand the data sheet. With magnetic fields I have no idea what range of values i should be looking for in a permanent magnet or the field emmited from a current. The sensor I ordered whenever a permanenet magnet approached it it instantly was saturated and have been lost since then. Would it also be necessary to have multiple sensors to account for different ranges?
The way i see this is there will be four components. Voltage regulator, microcontroller, LCD display and the sensor.
*Edit: LED display*
