Hi all
I'd like to get your feedback on the following project before I start pulling out cables from my main in my house.
I am trying to build a power meter which will ultimately be networked so that the data is accessible over the Internet. For the moment, I am trying to get the power meter running. The idea is to measure the current consumed in my home (the main current), and if possible, analyze the signal to see if I can recognize anything (spike detection, etc).
I am trying to use a **broken link removed** as sensor, thinking my house must draw more than 50A on full charge. I am powering it with a 15V DC source and intending to put a 25Ω resistor behind it so that the 0-100A, measured on a scale of 1:2000 becomes a 0-5V signal. I am also using an Arduino Duemilanove to capture the signal and transmit it to my computer. Ultimately, I'll want to use a XBee module or something similar to broadcast the signal.
Thanks
