Smart Electricity Meter

SMART-ELECTRICITY-METER

NXP metering technology enables one-phase, two-phase, and three-phase electricity meters used for measurement and registration of active, reactive, and apparent energy in residential and commercial metering applications. Along with its connectivity solutions for smart metering – like IEEE 802.15.4, ZigBee and Bluetooth® Low Energy - NXP addresses the challenges smart cities face for reliable, secure communications for remote metering and home energy management. With the growing consumption of energy worldwide, particularly in the residential market, utility providers need increasingly accurate and cost-effective energy metering solutions.
