Nowadays wireless communication has become day-to-day utility and we are well aware of the problems posed by radio frequencies involved in it like hazardous, inefficient in terms of power consumption etc. Visual light communication is supposed to be the possible solution to the above problems. Our project aims at building a basic data communication system that can transmit analog and digital data. We have transmitted audio signal over a distance of 30-35 cm and we have transmitted a text file of size 14 bytes at a distance of 3 cm (between led and photo diode) from one laptop to another laptop with single led within a fraction of second. We have used schemes such as hamming code and Manchester coding to have efficient and reliable system.

Today mankind is facing the worst energy crisis that has affected all segments of society. The gap between electricity demand and supply is widening with every passing day. According to energy experts the electricity demand is rising by 8-10 percent per annum. If this tendency continues, the electricity demand would rise phenomenally. Hence, it is the need of the hour to take pragmatic measures not only by increasing power generation capacity but also reduction of demand through energy conservation. Energy conservation is the only short term measure which can fill the gap between demand and supply. We can save a lot of electricity through energy conservation which must be taken immediately to cope with the shortage of electricity Simple changes in people's behavior can quickly lead to significant energy savings, but such changes will only happen if the people are aware of the energy consumption that they have the power to control. Our project is another step in this regard. It uses state of art technology to implement a new way of harvesting the available energy resources by simply monitoring them to get our real-time energy usage data graphically.

A purely analog controller has been developed for the speed control of a solar powered electric vehicle. An IGBT based cascaded boost converter is used as an interface between the PV array and the DC shunt motor. The designed controller automatically varies the duty cycle of the boost converter depending upon the desired speed of the motor. Speed control is achieved with proportional integral control and the tuning parameters of the controller have been obtained for the best system response. A difference amplifier has been introduced in the conventional analog controller design to ensure that the motor does not go out of control. Simulation studies and experimental investigations have been carried out on a laboratory size prototype of an electric vehicle - a DC shunt motor fed from a PV array and the results are presented.

The details of implementation of speech recognition system on the TMS320C6713 processor based DSK is discussed. This recognition system is based on the vector quantization technique at the acoustical level. There is a need to find out a new method of speech recognition system in which it should have less number of computations in computing the Minimum Euclidean Distance. It is also required to discover a new algorithm for forming a codebook in order to achieve a good Success rate. The efficiency of the implementation of this system lies in choosing an efficient method for MFCC vector generation and VQ codebook generation. The number of MEL filters used in the implementation is optimal and the method of design of MEL filters is efficient to keep MFCC feature vector length small to reduce the overall computational effort during training and testing phases.

In this paper we aim to design a smart home automation system with very low power consumption. Detection of change in the infrared radiation intensity in an environment due to the movement of humans is the key component of our project. The Passive Infrared (PIR) sensor sends output high signal to MSP430 controller board whenever it detects a person in its range. The MSP430 controller then sends the corresponding signals to Lighting module and an alarm module (using Audio booster pack C5000). A G.S.M module is used to send the real time alerts to the owner of the house if there are any unexpected developments like robbery etc.

A human hand can handle various objects by his hand, with better adaptive capacity and precision. In some hostile conditions, a need arises to replicate the human arm movements by some sophisticated manipulator. This paper illustrates the controlling of the movements of such manipulator i.e. robotic arm in accordance with the movements of human arm using real time image processing. It is kind of master-slave control methodology where slave i.e. robotic arm synchronously replicates the motion of master i.e. human arm. The arm is tele-operated i.e. wirelessly operated. There will be no wired connection between human arm and the robotic arm, which allows us to operate it in the wide range of upto 30 m irrespective of any disturbance. This paper gives a proper guidance to control a robotic arm (prototype of exact human arm) using real time image processing and is supported by the MATLAB codes, components and layout.

PV modules are increasingly used in battery charging applications in home inverter systems due to the power crisis faced in developing countries. This work aims at maximizing the use of solar energy by charging the battery as well as by supplying it to the loads when in excess. This system is implemented using two subsystems namely a charge controller and a Power Flow Management System(PMS). The charge controller is used to control the power flow from the PV module to the battery by operating in two modes. The Maximum Power Point Tracking mode(MPPT) extracts maximum power from PV panels and the Voltage Control Mode prevents overcharging of the battery. A 160W prototype of the charge controller is simulated in MATLAB/Simulink environment and is implemented in hardware. The operation of the controller in the two modes is verified and the relevant results are presented. A PV system implemented in houses involves various power sources and sinks. A control strategy is formulated in the PMS to balance the power flow among these elements using State of charge (SoC) of the battery as the criterion. The SoC is determined using coulometric measurements and is periodically recalibrated using Open Circuit Voltage method. The PMS is implemented and verified using experimental results and the energy savings are presented.
由于发展中国家面临电力危机，光伏组件越来越多地用于家用逆变器系统的电池充电应用。这项工作旨在最大限度地利用太阳能，通过给电池充电，并在电量过剩时向负载供电。该系统由两个子系统实现，即电荷控制器和潮流管理系统(PMS)。充电控制器通过两种工作模式来控制从光伏组件到电池的功率流。MPPT (Maximum Power Point Tracking)模式可以从光伏板中提取最大功率，电压控制模式可以防止电池过充。在MATLAB/Simulink环境下对160W的充电控制器样机进行了仿真，并在硬件上进行了实现。验证了控制器在两种模式下的运行情况，并给出了相关结果。在家庭中实施的光伏系统涉及各种电源和水槽。在PMS中，以电池的荷电状态(SoC)为标准，制定了一种控制策略来平衡这些元素之间的功率流。SoC使用库仑测量确定，并使用开路电压法定期重新校准。实验结果验证了PMS的实现和节能效果。
