A college project that I'm setting up requires a Tweet-a-watt and another XBee that measures current/voltage output from a Solar panel array that is in DC. I'm using a sensor that steps down the DC values to something that the XBee ADC can handle. I would then normalize the values on the receiver end. Questions:
- For the DC voltage/sensor Xbee, do I solder up the Xbee adapter like that for the tweet-a-watt transmitter or that of the receiver?
- Can I just hook up the sensor to the ADC on the Xbee and see the data on the receiver along with the tweet-a-watt data? Guessing that I will have to develop some Python for the DC readings.
I looked around the forums and could not find a similar question. I just wanted to be sure before I assemble the 2nd adapter board. Excuse me if its already out there.
BTW, the Tweet-a-watt is working and logging the data correctly
.I was going ask for help finding an alternative to the Google Powermeter since they shelved it
... Found Energylogger and it works great http://www.miloslick.com/EnergyLogger.html
