Hall sensor question Answered
I want to be able to measure the current draw through an AC wire in a confined space. I'm thinking hall sensors would be ideal for this due to small size and less chance of frying things (as opposed to a split-core transformer).
Unfortunately all of the hall current sensor projects I've found here on instructables are for the pre-made ACS712 board. This is a no-go for me because of size, the need for cutting the wire to make the connection, and also cost is a factor too.
Are there other options? I see a lot of three-wire sensors in through-hole transistor packages out there which would be ideal, but can you get the sensor voltage out of any of these, or is it strictly on/off?
Any hints welcome.
