So so Always reads 400mg+ does work if you put near a speaker magnet and goes from 500mg to 1000mg around smart meter.
It doesn't work right, it's a fake one!
Multiple ferrous materials (no measurable EMF whatsoever) yielded far higher results than an actively transmitting 1w multiband EMF source (800Mhz to 2400MHz). Meanwhile, a proper EMF meter yielded far different results. So a magnetometer yes, but EMF meter? Think again.
Helpful I was having trouble getting good sensor readings on an analog sensor. This app helped me identify the source of the noise that was causing the problem. Thanks
WORKS GOOD ON MY SG5 PHONE. THERE IS A THEORY, EMF ,READING COULD HELP U PREVENT CANCER.EXPOSER . AREAS.
Its good I like it, it works but I think it goes by sound, it I put it next to my cat, who is purring then it will go up
