Remote Volatge Monitoring

[WD8MBE]

Hi, name is Tom and I am new to the forum.

I have a solar and wind setup with everything located in my garage, including the storage batteries. I want to use 2 Xbees to monitor the voltages and send it to my PC located in the house.

Also, I would like to track these voltages over a given period of time. Can anyone help me on how to configure and wire the Xbees to monitor 10-15 VDC and 0-35 amps?

Thanks in advance,
Tom

Have you looked at the Tweet-A-Watt project? It should give you some ideas for starters.

Hi Franklin,

Thanks for your response. I now have XBee's setup using the Kill-A-Watt software. And I am displaying using EnergyLogger.

Now the voltage sensor input (AD0/D100) what type and value of voltage is it expecting? DC Voltage, Micro Volts, AC?

Just for experimentation, could I hook a 1.5v AA battery to Grd and AD0 and get a reading. By the way, I am using Parallax 5v/3.3v adapter board.

Thanks,
Tom

tweetawatt must be calibrated. thats why there is a calibration step. follow the tutorial for calibration and voltage checking
