by ADMIN 115 views

Introduction

Automatic street lights are a revolutionary innovation that combines environmentally friendly technology and security systems in one device. By harnessing the power of solar panels to absorb solar energy, these lamps can operate independently without relying on the electricity supply of the general network. The work process begins with the solar panel, which converts sunlight energy into electricity, stored in a battery for use when sunlight is not available, such as at night. This system is equipped with essential components, including the ATmega328 microprocessor, PIR and LDR sensors, to detect movement and damage.

The Main Components in the System

  1. Solar Panel: As the primary energy source, solar panels collect sunlight and convert it into electric current. This is crucial to ensure that the street lights continue to function throughout the night.

  2. Battery: The battery stores the electrical energy produced by the solar panel. When night falls or cloudy weather sets in, the battery supplies power to the street lights, ensuring they remain on from 18:00 to 06:00.

  3. Inverter and Adapter: After the energy is stored in the form of DC (direct current) in the battery, the inverter converts it to AC (alternating current). The energy that has been changed is then distributed to other components through the adapter.

  4. ATMEGA328: This microprocessor acts as the brain of the system, regulating when the lights turn on and off based on the time determined by the RTC DS3231. In addition, ATmega328 also serves to receive input from existing sensors.

  5. RTC DS3231: This real-time clock module not only ensures the lights operate at the right time but also features a temperature gauge. This module plays a vital role in maintaining the system's accuracy and reliability.

  6. PIR Sensor: This sensor plays a crucial role in the system's safety aspects. PIR (Passive Infrared Sensor) detects human movements by capturing infrared radiation. If there is suspicious activity, like someone attempting to steal the lights, this sensor will be active and issue a signal to the buzzer to make a sound as a warning.

  7. LDR Sensor: In addition to the PIR sensor, the LDR (Light Dependent Resistor) sensor can also signal if there is damage to the lamp. This sensor is sensitive to changes in light intensity and can detect any anomalies in the system.

Automatic Street Light System Benefits

The development of an automatic street light system that utilizes solar energy and is equipped with a security sensor not only reduces operational costs but also provides additional security to public infrastructure. The existence of this street light can reduce the risk of theft and vandalism, which often occurs in traditional street lights. Furthermore, the use of renewable energy helps in efforts to maintain the environment and reduce dependence on fossil energy resources.

Implementation and Testing

The implementation of the automatic street light system involves several stages, including the design and development of the system, testing, and deployment. The system was tested in a controlled environment to ensure its accuracy and reliability. The results of the testing showed that the system was able to detect human movements and issue warnings in a timely manner.

Conclusion

The design and implementation of automatic street lights based on solar power with a human movement detection system is an innovative solution to improve energy safety and efficiency. With a combination of advanced technology such as solar panels, batteries, and sensors, this system not only provides the necessary lighting at night but also protects public assets from criminal acts. With the development of technology and awareness of the environment, systems like this are expected to be applied more broadly in various regions to create a safer and environmentally friendly environment.

Future Work

Future work on this project can focus on several areas, including the development of more advanced sensors and algorithms to improve the system's accuracy and reliability. Additionally, the system can be integrated with other smart city technologies to create a more comprehensive and efficient urban infrastructure.
