Description: An Energy Monitoring Sensor is a device designed to monitor the energy consumption and efficiency of various electrical systems and devices. These sensors collect real-time data on energy usage, allowing users to identify consumption patterns, detect anomalies, and optimize resource use. Typically, these devices are equipped with IoT (Internet of Things) technology, enabling them to connect to networks and send information to analysis platforms. Key features include the ability to measure voltage, current, power, and energy consumed, as well as the capability to integrate with energy management systems. The relevance of these sensors lies in their contribution to sustainability and the reduction of operational costs, as they facilitate informed decision-making regarding energy use. Additionally, they are key tools in the transition to smart buildings and more sustainable cities, where energy efficiency is a priority.
