PIR Sensor Based Office Management
$102.17$67.31In this project our aim is to use Microcontroller for office management. This project presents design and implementation concepts for a office management. system based on microcontroller as central controllers. In this we have studied all technologies which are used for implementation for office management. In this dissertation, microcontroller is the crusial part.

Power Generation Using Piezoelectric Sensor
$110.58$98.56Day by day, the population of the country is increasing and the requirement of the power is also increasing. At the same time the wastage of energy is also increasing in many ways. So, reforming this energy back to usable form is the major solution. In this footstep power generation project, we are generating power with the help of human’s footsteps; this power is then used to charge battery. The power is stored in a battery that can be used to charge. This system is powered by Atmega 328, it consists of Arduino IDE, RFID sensor, USB cable and LCD. When we power on the system, the system enters into registration mode.

Prepaid Energy Meter
$180.30$168.28The concept of electronic energy meters has been introduced in the power sector to effectively record the units consumed for billing purposes and also monitor several other factors to reduce power theft and minimize losses that occur due to conventional electromechanical energy meters. This is a multipurpose project that integrates all the functions including a prepaid billing arrangement and automatic message sending system to the utility company. It may please be noted that it is truly not ausable commercial product engaging actual prepaid card but uses a set of switches for understanding the technology implemented behind it. This project uses an Arduino to which a GSM modem is interfaced. From here the message is sent to the phone number that is auto-saved by giving a missed call to the SIM number present in the GSM modem. There are a set of pushbuttons, which are used to load,any recharge amount required. Such arrangement is in lieu of an actual prepaid card for demo purposes. By pushing those buttons one can easily recharge the amount. As soon as the Arduino receives any recharge amount, a switch is set, to deliver power to the load. Thereafter consumption of the load power is calculated by the energy meter, which is interfaced to the Arduino through an Optical Isolator IC. The Arduino program then starts to deduct the recharge amount as per the consumption of load power. Once the recharge amount reaches zero then the Arduino cuts the power supply to the load through a relay driven duly by an NPN transistor and also sends a message to the phone number stored that contains all the billing information. Then again the balance is not available then go to the message in the gsm no available in balance

PRIORITY BASED SUPPLY SELECTION OVER GSM
$102.17$81.74The main objective of this project is to provide priority-wise power supply to a load, by selecting the supply source from any available one out of 4 such as mains, generator, inverter, and solar in the absence of power supply. The demand for electricity is increasing every day and frequent power cut is causing many problems in various areas like industries, hospitals, and houses. An alternative arrangement for a power source is thus desirable.

Railway Track Crack Detection
$146.64$134.62India has the world’s fourth largest railway networks, which carry out most of the commercial transport in India. The train transportation increased due to high speed, economical, environment friendly, safety and modern characteristics of railway system. Major problem with this transportation is the bad weather condition, which cause flaws and cracks leads to the damage of railway tracks.

Rf Remote Controal Home Appliances
$57.70$45.68This work presented here is to controlled independent home electrical appliances through RF based remotesystem. From any place without any line of sight around the house, RF based wireless remote control system can change the state of the electrical appliances either in on state or off state. The controlling circuit is built around RF transmitter and RF Receiver modules and decoder IC HT12D with few passive components.

RF REMOTE CONTROLLED FOUR QUADRANT DC MOTOR
$69.72$64.91The project is designed to develop a four-quadrant operation of the Dc motor remotely controlled by an RF Remote. This system could also be a really sustainable system for controlling the DC motor in four directions like clock-wise, counter-wise, reverse brake, and forward brake. It additionally features high-speed mode and low-speed mode in speed control.
