Open Energy Monitor Project

How to build an arduino energy monitor measuring mains voltage and current.

Open energy monitor project.

The next 20 years will see a revolution in our energy systems as we switch away from fossil fuels towards a zero carbon energy supply. Use at your own risk. The openenergymonitor project was founded out of a desire for open source tools to help people understand and relate to their use of energy their energy systems and the challenge of sustainable energy. The system is fully open source both hardware and software.

Our open hardware energy monitoring arduino compatible shield featuring the above circuit alongside voltage measurement for real power calculation. Go check it out. An in depth look at the basic principles of electricity monitoring sustainable energy and more. In order to overcome these limitations of existing energy monitoring systems this study presents an entirely open source low cost power monitoring system which is capable of many types of measurements for both loads and generation sources such as solar photovoltaic systems wind power microhydro biomass or fuel cells.

Monitor electricity temperature and humidity. These calculators are designed to help you determine the values of the components you ll need for the current transformer s used in the open energy monitor project. Please note these calculators do not take into account core permeability and core al value. An all in one 2 circuit energy monitor and base station which collects data hosts the emoncms software and can also receive data from other sensor nodes.

All hardware is based on the arduino and raspberry pi platforms.
