Energy saving is very necessary need in now a days. We are introducing Energy efficient centralized energy monitoring as well as controlling automatically through Internet of things. This proposed system demonstrates energy saving street light intensity control system with low maintenance.This is done by sensing the light intensity from surroundings by LDR Depends on the LDR status street light automatically controlled. Digitization of Energy meter readings in LCD and IoT module for status monitoring. We can control the street light loads though server if in case emergency. Proposed system saves the energy in day mode and it made system is automation. Digitalization of energy meter data through server. We can monitor and control very easily, simple fast access. All input and out modules are interfaced to ARDUINO Microcontroller which process input data and provide output with help of 5V regulated power supply. In this project we used Arduino ide software to write c program and compiling.

Internet of things (IoT) and fuzzy logic are very useful in increasing the efficiency and effectiveness of a system; this study applies both to the street lighting systems. The prototype of a street lighting control and monitoring system has been completed. The status of lights that are on or off and the value of the light intensity can be monitored by using IoT. The intensity of the light is fuzzy controlled by utilizing the presence of vehicles and pedestrians around the lights. The prototype is made with a scale against real conditions. Data is processed and transmitted using a microcontroller and Wi-Fi on the IoT module. Mobile applications have been used on smartphone interfaces to monitor and control lamps wherever they are connected to the Internet. Changes in the status of lights to turn on or off are done by the relay module. The fuzzy light intensity control system uses sensors and microcontrollers by utilizing the presence of vehicles and pedestrians around the lights. Performance evaluation has been carried out on a miniature street lighting with the results of monitoring and control following its function. An analysis of the resulting energy savings has been demonstrated.

Fluorescent Tube

A targeted energy analysis was carried out in a textile industry focusing on lighting system. It is observed from the study that the industry can replace the existing TL-D 36 W/54 fluorescent tube lights with energy efficient TL-5 28 W/865 fluorescent tube lights with electronic ballast. This has resulted in energy saving of 206388 kWh per annum. The corresponding CO2 mitigation is estimated at 167.174 t CO2/annum. An experiment was conducted to identify the exact light intensity of the proposed lighting system. The result shows that the light intensity has reduced by 11.1 % which is insignificant compared to energy saving and CO2 mitigation. The investment for the new lighting fixtures is estimated at INR 0.468 million with cost saving of INR 1.65 million which has return on investment of just 3.3 months.

Intensity Control

This research article gives an idea about advancements in energy saving of street lights and to reduce the power consumption. The pro-gramming terminology for building up the product to the Arduino board at long last, the framework has been effectively outlined and executed. Mainly using two sensor IR and LDR sensor to implement intensity control of street light.IR sensor is use to detect the motion of the objects and LDR (light dependent resistor) used to recognize day-evening. When light falls on the LDR depending on resistance of light the intensity of light is decreased or increase. The street light is automatically ON in evening 6pm and OFF till morning. Through mobile app also we can operate the street light. Using Arduino board for implementing the intensity control of street light.

Background:: In recent years, there has been a high demand for executing digital signal processing and machine learning applications on energy-constrained devices. Squaring is a vital arithmetic operation used in such applications. Hence, improving the energy efficiency of squaring is crucial. Objective:: In this paper, a novel approximation method based on piecewise linear segmentation of the square function is proposed. Methods: Two-segment, four-segment and eight-segment accurate and energy-efficient 32-bit approximate designs for squaring were implemented using this method. The proposed 2-segment approximate squaring hardware showed 12.5% maximum relative error and delivered up to 55.6% energy saving when compared with state-of-the-art approximate multipliers used for squaring. Results: The proposed 4-segment hardware achieved a maximum relative error of 3.13% with up to 46.5% energy saving. Conclusion:: The proposed 8-segment design emerged as the most accurate squaring hardware with a maximum relative error of 0.78%. The comparison also revealed that the 8-segment design is the most efficient design in terms of error-area-delay-power product.
