A local area network (LAN) power sensor measures and monitors the power consumption and energy usage in a LAN setting. Unlike USB power sensors that are specific to USB-connected devices, LAN power sensors track the power usage of various network-connected devices like computers, servers, switches, routers, and other networking equipment. These sensors are typically used in data centers, offices, and diverse networking environments and provide valuable insights about the energy consumption patterns of interconnected devices to administrators and IT professionals. LAN sensors help engineers gain a better understanding and management of power usage within the LAN to facilitate informed decision-making for efficient network operations.
