Hi, I have forgo my previous idea of Tesla coil as my final year project and now moved on in doing an AC power meter monitoring, which monitors the kWh, voltage, current consumption of a device and remotely controlled switch to turn off/on the device.This power meter should be implemented like a wall socket point.
I am using an MCU in this case, thus I need +5V and maybe other ICs too. This power meter should be implemented like socket point, in my country is a 240V point.
1.How do I get +5V dc supplies from live wire with AC power in the simplest & most efficient way without causing much consumption or distortion in the socket point?
2.How do I control it wirelessly? RF module to a receiver connected via usb to a laptop?
