IOT Based Energy Management System
The aim is to reduce energy consumption for small and medium scale buildings by implementing a lighting system that integrates Lighting control and sensor with QR code Generator and Scan. The sensor or light state or light intensity inputs can be received either from an external RS485 EnOcean transceiver (antenna) or via network variables from a LonWorks network.
The proposed solution plans to support light dimming, utilizing PWM (pulse-width modulation) control in addition to ON/OFF switching by the relay outputs. The application serves to provide the right amount of light where and when it is needed.
It contains the following modules:
- Home
- Light setup
- Zone handler
- QR handler
- Maintenance
- Settings
