New ozm3 three-phase version

After a quite busy period of tests and trials, the new version of openzmeter in its three-phase variant is here. Its development is a major step forward towards the reinforcement of the project and we believe that it will allow us to reach a larger number of people. Following the same philosophy as in single-phase

Single phase circuits basics

Single-phase alternating current (AC) is a main technology for efficient energy delivery across the world. Among its uses are lighting, low power electric motors or heating. It is characterized by a sinusoidal shape and varies in time so that the same pattern is continuously repeated. This energy system is characterized by a voltage with the

openZmeter in the press

We are pleased to announce that openZmeter has been noticed by the local mediafor the first time. Five local digital newspapers published about us and our labour at university (Universidad de Almería, Spain). Our university digital newspaper was the first one to publish an article about openZmeter and, within a week, four more local media

In this new version, major enhancements have been made to most of the basic modules, resulting in a much more stable and improved system. Operating system The first major change has been to switch the operating system from Debian to OpenWRT. This change

Paper published in journal Sensors (MDPI)

This is the second specific paper on the openzmeter device. It describes in detail its hardware architecture and provides measurements in a real scenario. Likewise, a comparison is made with commercial and professional devices that reveals the accuracy of the measurements obtained according to international standards.

First scientific paper published

The openZmeter team is completely delighted again. Recently, a new scientific article has been published in the prestigious journal Sustainability edited by MDPI. Our Ph.D. Student Eduardo Viciana did a great job and the result is his first international paper entitled “OpenZmeter: An Efficient Low-Cost Energy Smart Meter and Power Quality Analyzer”.   It is open
