This results in insertion to the budget. In addition to this, faulty lights may not come to the heed of the concerned authority for a long time which leads to the technical downside. This paper demonstrates a process of controlling the street lights in country like Bangladesh employing SIM900 GSM-GPRS Shield which comes up with the provision of manual control, semi-automated control as well as full-automated control. Keywords-GSM-GPRS shield, ATmega-328p, Clock module, PCF8574 IC, system design, prototype, implementation, software. I. INTRODUCTION Around 5% of total energy is consumed by the street lights, lighting of parking lots, pedestrian area along with park lighting [1] which contains both the working part and the wasted part. The wastage of the power occurs mainly due to the timing of manual operation of lights. This paper is a projection of a process which demolishes the wastage in case of Bangladesh. A practical implementation of this model will also be presented which took place in Mirpur Cantonment, Dhaka, Bangladesh. This model is structured using the GSM-GPRS shield. The whole model has the superiority to be controlled in full-automated, semi-automated and manual method. The GPRS part has the access to internet which can use the sunset and sunrise timing to allow the system to operate in full-automated method. On the other hand, utilizing the GSM part and RTC module, semi-automated control can be administrated. Here, either a particular set of time can be placed to switch on-off the system or just sending a mobile message can execute the same. Even if there is issue with these automated systems, there is also a feature of manual control method. Moreover, the proposed system has the option of detecting the fault associated with potential transformer and current transformer. The entire process is controlled by ATmega-328p microcontroller. II. LITERATURE REVIEW Suseendran et al. [2] represented the brightness controlling of the street light using sensors, based on IoT (Internet of Things), video vehicle detection and LDR (Light Decreasing Resistance) sensor. Each lamp unit encompassed two sensors- video vehicle detection sensor and LDR sensor. All the data were collected and processed on a regular basis which had required a huge data processing system. Lavric et al. [3] revealed a practical implementation of street light monitoring and controlling system employing WSN (Wireless Sensor Network System). The authors had focused on the software-based method and then performed a real-time implementation using limited number of lights. This archetype included Doppler sensor to allow vehicle detection. According to the appearance of vehicle, lights for that particular region increased intensity. Archibong et al. [4] worked with IoT based PV solar self-powered lighting system for street with anti-vandalism monitoring and tracking competency. LDR sensor switched the lights on-off along with an IR (InfraRed) sensor having the ability to save power. The anti-vandalism system was installed with a User Interface (UI), where the street lights communicated with the people and devices through wi-fi module at the control station. Prasad et al. [5] projected a case-study of Nagpur street lighting system, where LED lights were utilized along with motion detection system. The arbitration showed that energy consumption was lessen by 55% per month. Abdullah et al. [6] worked to provide a suitable system to minimize the power dissipation. The prototype comprised LDR, IR, battery and LED along with Arduino uno, which was skilled in increasing the intensity of light based on the speed of the vehicle. This project concluded that, this system will retain about 40% energy per month. Smart street lighting system also practiced in another way by Sukhathai et al. [7] using LoRaWAN in accompany with motion detector and illuminance sensor to mitigate the power consumption. In this model, every street light had been furnished with LoRaWAN communication module, which controlled the LED lights by exchanging data with main server. Mary et al. [8] investigated on the control of street lights using lamp unit, sensor unit and access unit. The lamp and the sensor units accommodated sensors for identifying motion and brightness of controller, LED device and communication device. For the access unit, Zigbee was used. Whenever there was any motion, lights’ brightness was proliferated otherwise it was dimmed or low. All the above divulged papers are prototype based. Only the work with WSN network system represented a field work with implementing the concept only for controlling four lighting units. This paper portrays a practically implemented method with control of 300 lights of 2.5km distance.
