Hi! My name is Rahim Saadiq, and I am a Mechanical Engineering student at South Mountain Community College. I am currently taking a Engineering Special Projects class where my team and myself require a high sensitivity Hall Effect sensor that is able to read the Earth's magnetic field strength between -1 and +1 gauss, maybe even as low as 0.2 gauss. Right now, it seems that we can not find such a sensor very easily...
Also, the sensor should be able to interface with Arduino of course...
Any help or advice toward finding such a sensor will be appreciated.
Thank you.
