Hall Effect Switch
Archiver
Posts: 46,084
I need to turn a device on through a waterproof housing. I plan to use a
magnet holder on the outside of the case. To turn the unit on, a magnet
will be placed in the holder adjacent to a Hall effect switch. But that's
as far as I have got.
Are there any reference materials available which will help me design a
circuit to switch a BS1 off and on in this way?

I don't think you can turn a Stamp on or off with a Hall sensor, if you are
talking about interrupting the power. You best bet would be to find a magnet
reed relay or similar than can handle up to 500ma.

Why not consider a reed switch? You are in Vancouver - give Burtek a call
and ask them about reed switches for alarm systems. There are many types
available and this style of reed switch (intended for alarm systems) are
robust and very reliable.

a logic level P channel MOSFET which can be used to switch power on
or off. Hall effect switches are used all the time in patient connect
devices in the medical field.
