It may be an alternative if the TA17-04 isn't sensitive enough. I just want a reliable switch.I see, this probably not what you are looking for but may be of interest to others who wish to measure current accurately. It does require some additional electronics to go with it.
There is obviously a number of ways to measure current and I think this is the best I've found for my projects.
Squirrel,Sorry folks, a bit too far out there!
Electricity = current and volts. Sultanas are more juicy than currents, oh well.
Motorhome fridge fan switching. In another post on a sister site it was suggested to switch fridge fans on and off with a temperature operated switch. This is fine unless you are somewhere very hot. The fans will stay on all the time.
So I was looking for a cheap and easy solution. This does not need any rewiring or connecting too the existing fridge. It senses the current flowing too the fridge.
