Blynk based overhead power line fault detector 
this circuit detecting the power lines short circuit faults and sending the damaged power line location with SMS and Blynk.
the power consumption of this circuit is just about 100nA. all MCU’s set to deep sleep mode and when the faults occurs, the generated EMF waking up the MCU’s.
thanks to blynk.
So, you have access to those kV lines? If so, a wire wrapped around a line won’t produce some free juice for your board?
yes we access to hot lines. we are working on it to harvesting energy from the hot lines.
Ok, I won’t ask you to share your future project as I won’t touch those lines with a 10 foot pole 
Very interesting application.
Share more info with us.
Thanks
