hi all, as you can tell i am new to this site, i am currently studying elecrical and electronic engineering at college and i am in my third and final year, but i am currently in the process of deisgning and making a project. I have come up with the idea of using a hall effect sensor and putting it around the lead that comes out of a soldering iron, (i have measured the ac current and it about .05 amps) and connecting this to a seperate circuit incorparating a tri ac that will then be connected to a fume extractor. So basically when you turn the soldering iron on, the hall effect sensor will detect ac current this will then switch the tri ac to turn the fume extractor on, here comes my problem...
I am not 100% sure what components i am going to need and i am un certain of how to connect it up!
any help and schematic diagrams and drawings will be much appreciated!!!
thankyou
