Hi,

I've got a STM32F051 Microcontroller and i'm wondering if anybody can give me any potential information on earth detection? I'm hoping to be able to detect whether ESD protection wrist bands are connected to their plug socket or not.

Cheers,
 

Why don't you do some sort of continuity tester circuit?

Also you've got the Fairchild KA2803B earth leakage detector, though don't know if it would work.
 

I saw that with a quick google search but as the live and neutral won't be involved with the device, I can't quite see that working unfortunately, thanks for the reply though!
