Harvard Engineering, world leader in the design, development and manufacture of control products and LED drivers for the lighting industry, has launched a new device called a SensorNode that enables presence detection for the company’s multi award-winning LeafNut monitoring and control system for outdoor and street lighting.
The SensorNode automatically overrides any scheduled dimming profiles on the system, returning the lights to full power for a specified period of time. The device operates via connection with an external presence detection unit, making it an ideal solution for installing on footpaths and cycle paths. Following recent concerns about turning lights off at night, the SensorNode allows local authorities to save energy through scheduled dimming, and maintain the safety of residents with increased light levels when required.
Russell Fletcher, sales and marketing director at Harvard Engineering, commented, “Our SensorNode provides the ability to override dimming profiles when more light is needed for a set period. This means that councils can still save energy from their lighting, but without the worry of compromised public safety because lights are brought back to full brightness when someone enters the area.”
LeafNut has been installed by over 100 local authorities across the world and is helping to save up to £46 per street light per year in energy costs, and up to 100kg of carbon per street light per year.
