Tweet-a-watt uses WL-520gU for Data Acquisition
March 31st, 2009 by Jeff
Ladyada of Adafruit Industries created the Tweet-a-Watt to monitor energy usage in her apartment.
Each Tweet-a-Watt device contains some power monitoring electronics and an Xbee module. The Xbee modules relay energy usage data for each Tweet-a-Watt back to a single receiver, which collects the data.
In staying with the overall green theme of the project, Ladyada used an Asus Wl-520gU wireless router to control the receiver and collect data. This is the same router I used for my Wifi Radio project! The WL-520gU consumes ~5W and has enough horsepower to run the python data acquisition scripts while still acting as a cablemodem gateway.
