enSense™ Noise Sensor

The new series of enLight® enSense™ sensors have been designed to work in harmony with the enLight platform and use the network created by the upgraded lighting infrastructure to carry the data from where it is being recorded to where it is needed in the cloud. The enSense family includes microclimate, road temperature, traffic volume/speed, flood warning, parking management and a variety of gas sensors for measuring air quality and gas build up.

The enSense Noise Sensor can be used to measure background noise levels to monitor adherence to regulatory requirements or it can be used to listen for specific frequencies such as the sound of breaking glass, a gunshot or a road traffic accident. Acceptable limits can be set for different frequencies or for a rolling average across a particular time span and breaching those limits can trigger some form of action such as a message to an enforcement officer or to be logged.

All sensors in the enSense range come in a standard 32mm cylindrical package for easy mounting within an enLight HID lantern, or they can be mounted on the lamp post itself using a bracket. The current set of sensors are wired into the enLight enTalk™ network by connecting to either the enLight entelli-Ballast™ for HID lamps or the enLight enLink™ LED adapter in a loop-in/loop-out configuration.

Seamless integration with enLight lighting platform



All enAct devices are designed to work seamlessly with the enLight platform. Most of the devices can be mounted in any DIN rail enclosure using a GST mini connector for mains input. Devices providing high power output use the same GST Mini connector.

All devices include two RS485 connectors for connecting to an enLight DOLFin® Pro, leaving one socket free to connect a single or a daisy chain of other sensors or actuators – subject to total power draw.

Away from the vicinity of the mains powered enAct device, wireless enLight enSense™ devices (coming late 2017) can connect to the network via the DOLFin Pro for their data feed to be sent on to the enLight enGauge™ API.

Cost effective smart city deployment

By deploying the enLight platform on lamp posts across the city, town or campus, a whole host of smart applications can be realised by utilising the network created by the lights. Multiple wireless technologies do not need to be funded and the inherent value of the street light estate increases as it allows resource reduction or increased efficiency projects to be deployed, without the major capital cost of their own networks. The enSense sensors are fully compatible with the enLight enCore™ Management System or via other management platforms through the enLight enTalk API.
