Welcome to CuVoodoo,
the sorcery of copper.
to measure the voltage of mains electricity
certification marks
0.14 A * 227 V * 0.91 = 32 W as show by the power meter
because 0.19 A * 230.8 V = 44 W, the power is cacultated differently (probably including the power factor)
the clearance is pretty small
I meant a resistor to measure the voltage based on the current going through the coil
probably this way you can connect the power meters in parallel on the same serial line (once the addresses have been configured)
Atmel ATmega328P
I forgot to mention its name: pulseview
pulseview just crashed
something went wrong with the audio recording
it's actually called residual-current device (RCD)
with floating I meant hanging lossly around
