Open-source energy monitoring system is being developed.
This is a project to develop and build open-source energy monitoring, control and analysis tools for energy efficiency and distributed renewable microgeneration.
The design uses the Arduino to read pulse signals from the utility meter to get information about overall consumption. It also uses current transformers to read consumption details from independent lines, and temperature sensors to get temperature readings.
The information will be displayed on a wireless graphic LCD display, or accessed from a internet connection provided by the Ethernet or WiFi. The system will be accompanied by emoncms software which will provide data analysis for the user. Check out a demonstration of the system in the video below.
