Energy saving through led replacement for street lighting

Kaneka Malaysia Sdn. Bhd totally have 182 units of street lighting which is 53 percent are High Pressure Sodium Vapour (HPSV) lighting. All street lighting was controlled by timer. This traditional method is out of date and huge of energy waste mainly due to timer malfunction. Moreover, HPSV street lighting is very costly to maintain. On February 2019, audit for street lighting was carried out and result of energy consumption was 317.56kWh per day or 114,321.02kWh per year. Motivated from this audit, HPSV street lighting was proposed to replace with highly efficient Light Emitted Diode (LED) street lighting. To realise this project, the prototype was built by implemented a smart system of LED street lighting controller to gain reduction of energy consumption and introduction of smart controlling technique by using Internet of Things (IOT). The prototype is design by employ Arduino NANO, PIR Motion Sensor, ESP8266 module and Blynk platform as wireless communication tool. The brightness of the LED street lighting being controlled depends on the motion detected from 11:00pm until 7:00am. By implement this idea, energy consumption will be save 50 percent and cut 20 percent of maintenance cost
