Wow, so it basically measures the material that it's near to! That's cool. I know that microwaves are well-adsorbed by water (such as in bodies), is that how this works, does it piggyback on the 2.4 GHz antenna? Can I read this sensor's output via some Android API or a device file (with root perhaps)?
