I've purchased some I-Sensor circuits from Uxcell Products. They are a simple Toroidal current transformer with a rectifier and relay on board. The actual product I purchased has an ID on back:
Logo-I-Sensor v1.1. It scales 0-5A and runs from 5v.
Does anyone know how to obtain a circuit diagram/schematic or pin out for these things?
There's three pots on board, obviously one can play with this thing and figure out stuff, but I'd
prefer to RTFM...
I recently bought a Logo-I-Sensor v1.1. through AliExpress. It contained a currenttransformer 1000:1 for 50A to 50 mA.
I managed after some laboriously staring and checking about all connections with a Multimeter (in connection mode) to reverse-engineering the circuitry.
Mind, I could not find the exact capacitance for the small smd capacitors, nor the type of transistor used and the diodes.
So you'll have to check it.
