CONSTRUCTION OF MICROCONTROLLER BASED VEHICLE SPEED ALARM.

ABSTRACT  The project is based on Construction of microcontroller vehicle speed alarm system which automatically warns the driver by activating a panic alarm which is triggered on when the driver exceeds the speed limit set in the system which also stops the alarm when the speed is reduced below the set speed limit. A speedometer system is used to monitor the speed of the car. The voltage output of the speedometer system is used to set the time the alarm comes on. The other component parts ...

HOME CONTROL SWITCH AUTOMATION USING GSM COMMUNICATION

ABSTRACTThe advantage of cellular communication like GSM technology is a potential solution for such remote controlling activities. GSM-SMS technology can be used to control household appliances from remote places. Remotely, the system allows the home owner to monitor and control his house appliances via his mobile phone set by sending commands in the form of SMS message and receiving the appliances status as well. This system provides ideal solution to the problems caused in situations when ...

PATIENT HEARTBEAT AND TEMPERATURE MONITOR

AbstractHeart beat rate means the number of heartbeats per unit time, usually expressed as beats per minute (bpm). The human heart pounds to pump oxygen rich blood to the muscles and carry cell waste products away from the tissues. Heartbeat rate can vary according to the demand of the muscles to absorb oxygen and excrete carbon dioxide changes such as during exercise or sleep. It also varies significantly between individuals based on age, fitness and genetics. This means that the heart must ...

DESIGN AND CONTRUCTION OF AUTOMATIC PHASE SELECTOR

AbstractAs the growing population of human race widens the gulf between energy supply and energy demand, the imbalance in energy availability sent researchers into excavating for a way of settling this age long squabble. A lasting solution is vested on alternative use of the renewable energy source, a project that is yet to be widely applied. Hence, the continuation of the unsettled yearns for sufficient power. Consequently, the power lines are frequently over loaded resulting to a trip of po...

DESIGN AND CONSTRUCTION OF AN INVERTER TYPE ARC WELDING MACHINE

AbstractWelding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two or more pieces of metal to make the act as a single piece. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint. Because of its strength, welding is used to join beams when constructing buildings, bridges and other structures. Weld...

DESIGN AND CONSTRUCTION OF 20WATTS WIRELESS PUBLIC ADDRESS SYSTEM

ABSTRACTIt has become inevitable that there would be communication and due to the inherent limitation of the human voice, the public address system came to being. A public address or “P.A SYSTEM” is an electronic amplification system with a mixer ,amplifier and loudspeakers, used to reinforce a given sound , e.g a person making a speech, pre-recorded music ,or message and distributing the sound throughout a venue . The voice signal is passed through a microphone , which converts the sound...

DESIGN AND INSTALLATION OF 200 WATT SOLAR POWER SYSTEM

ABSTRACTThe 200W solar system was determined by load assessment, solar panel number determination, battery requirement and then inverter sizing. A complete solar panel rated at 200w was however purchased, together with 2 no. 150A solar battery, 1500W inverter and also 10A charge controller. These were assembled together with necessary protective gadgets like cut out switches; to give the 200W expected. The solar panel was mounted outside the building to allow for maximum collection of sun ene...

DESIGN AND CONSTRUCTION OF A 60AMP THREE PHASE AUTOMATIC CHANGE OVER SWITCH.

ABSTRACTThe design and construction of a 60A, 3-Ф automatic power changeover from public utility supply to generator and vice versa was aimed at providing a useful system for use in our homes or offices. The system was achieved with a 66A 3-Ф contactor, 100mA transformers and relays. The system turns on a generator when the public utility (PHCN) is off by cranking the starter and a provision was made to stop cranking when the generator is fully started. A delay was provided to stop the gene...

CONSTRUCTION OF RADIO FREQUENCY GSM SIGNAL JAMMER

Abstract A wireless signal jammer is a device which blocks transmission by creating interference. This wireless signal jammer can be categorized into the Radio Frequency (RF) jammer and GSM jammer.A Radio Frequency jammer is a device used to disrupt or prevent communication via a broadcasted RF signal. It is an RF and GSM frequency disrupter commonly known as wideband radio frequency (RF) and GSM cell phone jammer. Simultaneously, they can blocks all commercial FM broadcast band (87.5 MHz to ...

CONSTRUCTION OF AUTOMATIC WATER LEVEL CONTROLLER FOR BOTH OVERHEAD AND UNDERGROUND TANKS

ABSTRACTAutomatic water level controller for both overhead and underground tank is designed to monitor the level of water in a tank. It displays the level of water and when it is at the lowest level; a pump is activated automatically to refill the tank. When the tank is filled to its maximum capacity, the pump is automatically de-energized. Several circuits are put together to ensure proper working of this design, and the block diagram includes the supply unit, the micro-processor unit, the s...

CONSTRUCTION OF A MICROCONTROLLER BASED T-JUNCTION TRAFFIC LIGHT CONTROLLER

ABSTRACTT-junction traffic light controller is such a device that will play a significant role in controlling traffic at junctions, to ease the expected increased rush at such junctions and reduce to minimum disorderliness that may arise, as well as allowing the pedestrians a right of the way at intervals rather than being struck down when in a hurry to cross the roads. Such an electrical system with a touch of electronics that control the flow of traffic in a pre-determined sequential patter...

CONSTRUCTION OF A GSM BASED HOME AUTOMATION USING AVR

ABSTRACTWith advancement of technology things are becoming simpler and easier for us. Automatic systems are being preferred over manual system. The purpose of this project is to design and construct A GSM based home automation using AVR. Using GSM networks, in this project a home power control system has been proposed that will act as an embedded system which can monitor and control appliances and other devices locally using built-in input and output peripherals. The system has a delay of 2 m...

CONSTRUCTION OF METAL DETECTOR

ABSTRACTMetal detectors are electronics sensors that indicate the presence of metallic object without making physical contact with object. They are effective and useful security tools employed in strategic places such as airport, bank, stadiums, government houses and also in production industries to detect presence of metallic object on person luaggages, consignments foods, drugs garments etc. The study present a metal detector comprising a radio frequency oscillator, demodulating unit, trigg...

CONSTRUCTION OF A MICROCONTROLLER BASED GATE

ABSTRACTMicrocontroller based automate controller is a project design of a system that is used in operating a gate automatically. The system opens the gate automatically when a human being or car is about to enter a compound or exit a compound. The system works by sensing the light rays from the head lamp of the vehicle. The light ray is sensed and signal is used in operating the gate. Different blocks of circuit are put together to ensure that the system works perfectly as desired. The block...

CONSTRUCTION OF A MICROCONTROLLER BASED SECURITY DOOR USING SMART CARD

ABSTRACTThis project shows the construction of a microcontroller based security door using smart card. It is aimed towards programming the microcontroller to control the hardware in sliding door.
