This project proposes the energy management for smart environment. The overall control scheme is mainly governed by an embedded microcontroller. Economic crisis and the risen energy price have forced every country to reduce their energy usage and try to be economical on energy consumption. In this project IR sensors are used to find out the intruder enters the home and the devices are controlled using zigbee (wireless transmission). The system will count the number of human presence in the room or hall. This process is useful to save the electrical power and the system will turn on/off every plugged electrical appliances including light bulbs, fans, TV, etc. LDR senses higher light intensity at day time so that the relay will turn off the light bulbs, the devices will be automatically turned on at night times, and this will typically save the electricity. The temperature sensor used to sense the temperature range of the home, if it exceeds the threshold temperature fan will be automatically turned ON using relay, when temperature reaches normal condition relay will turn OFF the fan. The whole process is based on the human count inside the particular room/hall. Thus based on the human count, every devices inside the room/hall is controlled using sensors and zigbee technology.

INTRODUCTION |
The indoor location information is important for a heating, ventilating, and air conditioning system, illumination adjustment, humidity control, robot service, and so on. Many researches discuss indoor human and robot localization systems however, most of these systems are imprecise, cannot manage multiple targets, or have expensive implementation costs. These different localization techniques include: Active Badge that used IR sensors, Active Bat that uses ultrasonic sensors, Easy Living that used vision sensors, Motion Star that used a dc magnetic tracker, and RADAR that used a wireless local area network. Irfan et al. developed a neural-based approach to obtain the location of user. |
In order to detect the presence of resident the location-aware system uses an array of IR sensors. IR sensors which is present on the ceiling with overlapping detective areas with adjacent sensors, can detect the presence of a resident. This system can be a invalid when there are multiple targets or at vacant zones are present.. In this study, we propose an indoor localization and monitoring system, which is based on a wireless and IR (WIR) sensory fusion system. The location information obtained from the sensor and RF propagation model can be improved with the WIR system. We also propose a WIR inference algorithm, which can generate a more reliable positioning estimate of targets. This system aims to accurately locate a target. |
A WIR localization system can monitor multiple targets with relative good resolution. The main contributions of this study are as follows. |
1) Develop an RF and IR integrated system, which is useful in locating and monitoring people and robots in an indoor environment. |
2) Develop an inference-based algorithm for wireless and sensory fusion system, where the proposed algorithm can be extended to binary sensor localization system. |
3) Propose a methodology that can register vacant zones to improve the accuracy of localization. |

III. PROPOSED SYSTEM |
In this project the transmitter consists of IR sensor, temperature sensor, LDR, and zigbee for transmission. The intruders entering the room can be counted using the IR sensors that are fixed near the entrance, whenever the intruders enter the room or hall the count will be shown using LCD (Liquid Crystal Display). The temperature sensor senses the temperature that is present in the room and the sensed temperature is used to control fan based on the temperature. If the temperature exceeds the threshold value the fan will be turned on. The fan will be turned off if the temperature is below the threshold value. The LDR(Light Dependent Resistor) is used to sense the light luminescence and it is used to turn off the devices if the luminescence is high.The various applications of LDR include smoke detection, automatic lighting control, batch counting and burglar alarm systems. The multichannel ADC is used to convert the analog values to digital values from Temperature and LDR sensor. The Zigbee is used for wireless transmission between transmitter and receiver. |
At the receiver side relays are used to control the appliances, thus the number of appliances can be controlled based on the human count, here zigbee is used for wireless transmission. Based on the human count the appliances can be controlled,and the energy consumption can be minimized based on the intensity and the room’s temperature. The LCD (Liquid Crystal Display) is used to display the number of human present in the room. |
The system will respond to the presence of human and various parameters such as amount of light present in surrounding, temperature around the surrounding. The system will reduce the power consumption and usage according to number of human in the location. |
