Implementation of Sensor based Energy Conservation System for College Library

Abstract

The lighting libraries and maintaining fans and lights need an extensive amount of energy in the majority of educational establishments. Nevertheless, this may lead to more expenses and wasteful energy use. We have created an improved lighting control system to solve this problem and reduce energy consumption during daylight and vacant hours. This system makes sure that the library\'s light connections and fans stay off while no students are present and turn on automatically when they do. For the purpose of managing the automated lighting system, we created an integrated module. The contrast of the library is determined as well with an LDR sensor.

Introduction

I. INTRODUCTION

Supplying access to energy is still an issue for worldwide, one that is frequently made worse by frequent blackouts. As a result, there is a growing awareness of the necessity of conserving electricity, especially in educational settings where it is common to leave fans and lighting on in empty rooms. Even while automation and smart lighting systems have been the subject of much study, there are still many issues with the solutions that are now in use, particularly with regard to their affordability.
Our team has created an advanced automated lighting control solution specifically for libraries to address these issues. Our technology incorporates sensors that are thoughtfully positioned around the room to go beyond conventional methods. To ensure accurate presence detection, these sensors are arranged in a grid. With the help of this cutting-edge configuration, we can turn electrical devices on or off intelligently based on where they are located, guaranteeing efficient use of energy and minimizing waste.

II. LITERATURE REVIEW

Academic and standards associations have focused on the Internet of Things' (IoT) integration with automation in the home and school. The goal of this integration is to automate a variety of tasks, such as intelligent transportation systems, home automation, and classroom interactions, by utilizing wireless operating technologies and high-speed networks.

[1] The idea behind Internet of Things (IoT) in home automation is to link  common appliances to the internet so that they may be controlled and communicated with remotely using portable devices like smartphones. This makes it easier to automate electrical appliances in homes, such as lighting and fans that adapt automatically according to light intensity and room temperature, respectively. The suggested systems are centered on using Internet of Things technology to control household appliances, manage fan speed, and save energy.

1. IoT technologies are utilized in the context of classroom automation to implement energy-efficient environmental condition monitoring and control. This includes the use of temperature sensors to control fan operation based on room temperature, LDR sensors to measure brightness, IR sensors to identify the presence of students, and ultrasonic sensors to detect human presence. These steps are intended to cut down on energy use and waste during daylight and vacant hours.

III. INFORMATION OF PIR SENSOR AND RELAY

The PIR sensor, the relay, and the LED make up the circuit for the suggested setup. The regulator IC in Figure 1 changes a 12V DC input into a 5V output. The micro-controller, LCD, and RF module are all powered by the regulator IC's 5V output. Ten SPDT relays are under the driver IC's efficient control for switching. A microcontroller's limited current and possible voltage needs usually prevent it from directly operating a relay with just a 5V signal. In order to appropriately energize the relay, the driver IC receives a 5V signal from the micro-controller and converts it to a 12V signal. When coupled to a 16MHz crystal oscillator, the ATmega328 micro-controller facilitates interface with a driver integrated circuit. Electronic systems can have automatic power on/off capabilities by integrating resistors, capacitors, and a 16-character LCD into a circuit.

The RF module has a maximum communication range of one kilometer and runs on the 2.4GHz frequency band. It may enable simultaneous communication with several RF modules and provides communication rates more than 56 Kbps. 5V capacitors are used to lessen load variations on the regulator integrated circuit.

IV. ADVANTAGES OF PROPOSED SYSTEM

1. Energy Efficiency: When spaces are vacant, the system may sense occupancy levels and modify HVAC and lighting settings to use less energy.
2. Cost Savings: The college may reduce utility costs by optimizing energy use, which might eventually result in considerable cost savings.
3. Environmental Benefits: Cutting back on energy use also means minimizing the library's carbon footprint, which helps with sustainability initiatives and environmental preservation.
4. Automation and Convenience: With sensors installed, the system can turn lights on and off automatically, saving energy and providing convenience for both library personnel and users.

V. COMMERCIAL USES

There are unparalleled advantages to deploying sensor-based energy saving systems across a range of commercial industries. Based on occupancy patterns, these systems optimize lighting, climate control, and equipment utilization, resulting in considerable cost savings and environmental sustainability. The benefits are numerous and may be found in anything from office buildings to industrial plants, retail establishments, and entertainment venues.

1. Lower operating costs by managing energy resources effectively.
2. Conserve energy to support environmentally beneficial behaviors.
3. Conserve energy while making sure the residents have a comfortable space.
4. Adapt equipment consumption, lighting, and temperature control to occupancy patterns.
5. Relevant to a range of business sectors, such as retail, entertainment, offices, and hospitality.

VI. FUTURE SCOPE

The next steps for our college library's energy conservation system include adding sophisticated sensors for increased precision, tying in with the building management system for centralized control, making use of data analytics for optimization, interacting with users to increase awareness, incorporating renewable energy sources, and expanding the system to other campus buildings for an all-encompassing sustainability strategy. These actions will encourage sustainability and energy conservation on campus even more.

Conclusion

To wrap things up, the installation of a sensor-based energy-saving system at our college library is a big step in the direction of environmentally conscious and sustainable resource management. We have effectively streamlined energy usage by cutting down on wasteful consumption and keeping a suitable climate for research and study thanks to the incorporation of sensor technologies. This initiative demonstrates our dedication to creating a greener campus and shows how creative problem-solving can be applied to meet contemporary issues.
