A Smart Meter is an advanced device that measures energy consumption in real-time. Unlike traditional meters, which require manual readings, smart meters automatically send usage data to utility companies. This technology helps consumers monitor their energy use more effectively and can lead to more efficient energy consumption. Smart meters are often part of a larger system known as a Smart Grid, which enhances the reliability and efficiency of electricity distribution. They can provide detailed information about energy usage patterns, enabling users to make informed decisions about their consumption and potentially reduce their energy bills.
