#100622 - bar magnets?
Responding to: ???'s previous message
Hi steve,
By 'Bar magnets' did you mean the magnets which are used in refrigerator doors to keep the door closed ? i thought that they are so weak for this purpose !
and about the speaker magnet i've had tested the sensor with the edges of the Speaker magnet , which is about 7 mm's width. that didn't triggered the sesnor also :( .

from UGN3213's datasheet :
"North pole to branded side Typ: -48 G"
can some body make a G (Gauss ?) sensful for me , how much power has a 1 G and is a 48 G an overkill(wihch is the typical sensitivity of the UGN)

i'll try to find more magnet and test them also.
