Introduction |
| The electricity meter is one device that no household connected to the grid can escape, and the technology utilized by analog meters (the most common type) dates to the late 19th century. However, engineers have recently developed a solid state electronic meter that sends electricity consumption readings wirelessly. This new meter eliminates human error and allows utility companies to monitor their systems more accurately. | | We were always interested in these meters, but had trouble acquiring one for a teardown -- it's not like you can just walk into a Best Buy and pick one off the shelf. Thankfully, the generous folks over at [link|http://www.elster.com/|Elster] were kind enough to send us one of their WatthourREX2 meters for thorough dissection! | | | The [link|http://stopsmartmeters.org/|controversy] surrounding the implementation of smart meters prompted us to take a close look at their hardware to see what exactly makes these devices tick. |
