An Energy-efficient Microcontroller-based Smart Light Controlling System

2021

In this work, an energy-saving smart light controlling system has been proposed that can main-tain the desired intensity of light in a room automatically. Unlike the conventional light control system, the proposed system splits a large room into several zones and analyzes the light inten-sity of each zone; hence, the controlling unit adjusts the light intensity to the desired level. The main controlling unit consists of a light sensor, a motion sensor, a relay with a driver unit, an LCD display, etc. for controlling light efficiently to reduce the power waste. The sensors meas-ure the intensity of light, based on the standard light intensity data chart the controller units make a decision how many light bulbs are needed to be switched ON/OFF in a particular zone. Moreover, the system automatically switched-OFF all light bulbs when there is nobody in the room. Proteus design suite 8.0 is used to design and simulation of the proposed system. Moreo-ver, the PCB layout is designed using...

In this paper, a room light management system is proposed based on real time clock and PIR sensor which is named as an automatic light management system (LMS). This proposed system will be able to provide the necessary intensity of light on various timings and with satisfaction of users and will save a lot amount of energy also. In this paper the light management system and the algorithm which helps to decide whether to switch on or off the lights are discussed. The decision making algorithm will check whether any occupants are there in the room and if any occupants are there, then it will check the current time of that particular location and based on the time it will decide the status of light. Our proposed system can promise to minimize the energy consumed for lighting in a room and to provide it efficiently with user satisfaction.

Smart Building Lighting System

IOP Conference Series: Materials Science and Engineering, 2018

In a building, lighting contributes 20-60% of the total consumption of electrical energy usage. To turn on and off the lamp with the switch manually sometimes people forget to turn it off when leaving the room. This resulted in the inefficiency of energy and cost, where the lamps work not based on need. To overcome this problem designed a lighting control system using internet of things concept so that the lights can be controlled and monitored remotely. This control system is designed using Arduino Mega 2560 as a microcontroller, relays as connectors and electric breakers voltage lamp and motion sensor as a switch that turns off the lights when there is no person in the room and indicator of the activity in the room. In addition, outdoor lights are lit in accordance with a predetermined schedule for more efficient power usage. With lighting control system is expected to reduce consumption of electrical energy usage so more efficient.

Development of Microcontroller Based Temperature and Lighting Control System in Smart Home

International Journal of Scientific Engineering and Technology Research, 2014

Recently, smart home has achieved evident interest due to consideration of an ideal living home with advanced technologies. Smart home technology is a good choice for people not only care about security but energy saving as well. Besides, energy saving is considered as one of the most important issue affects the consumers, power system quality and the global environment. The obvious point of smart home is that it is automatically adjusted to the desired state through interactions between the physical condition and electronic devices. This study is mainly mentioned the microcontroller based temperature and lighting control system for energy saving in one-story building with six room's smart home. The microcontroller is the brain of the system for interfacing and controlling the system. Therefore, in this paper, 40-Pin PIC18F4550 High-Performance, Enhanced Flash USB Microcontroller is applied to maintain the room temperature range of smart home as 25 ° C ± 5 ° C. Then, the temperature and lighting sensors are used to sense the real condition of the room of smart home. This research is a platform to be continued for the future smart control applications.

Automatic room light intensity detection and control using a microprocessor and light sensors

IEEE Transactions on Consumer Electronics, 2008

In this paper we propose a design using both a microprocessor and light sensors for automatic room light detection and control. Our design, the HLCM (Home Light Control Module) which will be installed in every light fixture of a family, is made up of four blocks: the pyroelectric infrared (PIR) sensor circuit, the light sensor circuit, the microprocessor and the RF module. By using the PIR sensor circuit, the HLCM detects if a human body enters the detection area or not. If there is no human body present, all controlled lights are turned off. If there is, the HLCM detects the light intensity under the environment and maintains sufficient light by controlling the number of lights. We have also integrated an RF module to transmit and receive the data from each HLCM so we can control different lights in different regions. The result of using the HLCM shows that the total power consumption can be reduced.
