This is a demo application of AMI's Nano TeslaSensor(MI-CB-1DJ USB Type) which can detect ultra-small AC magneticfield like 1nT(=1/50,000 of geomagnetism).

All you have to do is connect the sensor to a USB Mini-B cableand then connect to a USB-OTG(On-The-Go) adapter/cable and pluginto your tablet. The application detects the sensor if you alreadyinstalled it. This application has been designed and tested usingNexus 7(both 2012 and 2013 models). But It could work on any tabletwith USB-OTG capability under Android 4.0 or later.

If you are interested in evaluating the sensor or have anyquestions, please contact to Aichi Micro IntelligentCorporation(ami-info@aichi-mi.com).
