Power over Ethernet sensors improve smart city efficiency

10 July 2020

Monnit Corp. has introduced Power over Ethernet (PoE) sensors for smart buildings to conserve resources and operations and enhance comfort.

The sensors plug directly into a building’s PoE infrastructure to remotely monitor critical systems and infrastructure for asset-damaging hazards like water leaks. If a system exceeds specific thresholds, a municipality is alerted via text, email or call.

PoE can be used for the internet of things in smart cities to address anything from server rooms and data centers that are compatible with Ethernet. The PoE sensors can also be plugged into Ethernet infrastructure and powered via AC adapter if a building does not have PoE.

The Monnit sensors support commercial enterprises and industrial firms by collecting environmental or power data and sharing it with the building management systems. The sensors also host simple network management protocol (SNMP) and Modbus TCP traffic to transfer data into supervisory control and data acquisition systems. This allows data sharing in HVAC or optimized lighting, lower overhead and reduced emissions.
