Design and implementation of dimmer based smart street lighting system using raspberry Pi and IoT

Abstract

In olden days street lights were not operated in an automatic way. Automation of street lights has become apparent these days. But we can notice that we do not require high intensity light during night hours, i.e. when there is no traffic, no people in the streets or on roads and even in the early mornings. As per requirement, the light intensity can be reduced using dimmer circuit. Light dependent resistor (LDR) sensors are used to sense the darkness and Passive Infrared (PIR) sensors are to detect the objects. Raspberry Pi (Master node) and Arduino (Slave node) will communicate each other and they help the proposed system to work more effectively. Current sensor and Voltage sensor are used to measure the current and voltage respectively. By reducing the intensity at these times, energy can be saved to some extent and the data is uploaded to the cloud. We can monitor and control the street lights in a smart way as per our requirement. Fault detection, minimization of cost, reducing the loss of electricity and man power are also possible. Hence, this proposed smart street lighting system will be helpful to the society in cost effective way.

An Automation System for Controlling Streetlights and Monitoring Objects Using Arduino

“…Hence, the wastage of power from street lights is one of the noticeable power losses, but with the use of automation, it leads to many new methods of energy and money saving. In this regard, controlling the lighting system using a light dependent resistor (LDR) [ 10 ], infrared radiation (IR) obstacle avoidance sensor [ 11 ], and Arduino [ 12 , 13 ] together are proposed in the past [ 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 ]. In previous literature, the street light systems are based on LDR [ 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ], and most of them are passive infrared receiver-based systems that are controlled with timers and analogue circuits.…”

“…Furthermore, streetlight control with the use of solar energy [ 34 , 35 ], and ZigBee based system to control streetlights [ 36 ] have also been implemented. Distinguished from turning the electricity ON/OFF, another approach is introduced to DIM (half of the maximum brightness) the light [ 27 , 31 ] during the hours where traffic is sparse, which might be useful for reducing the power consumption, but with the electric bulbs under a continuous usage condition.…”
