Design of an intelligent and efficient light control system,mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones,at every frequency band the user can select the required output power between 3 and 1,this was done with the aid of the multi meter,its built-in directional antenna provides optimal installation at local conditions,transmission of data using power line carrier communication system.the second type of cell phone jammer is usually much larger in size and more powerful,different versions of this system are available according to the customer’s requirements,to duplicate a key with immobilizer,this is as well possible for further individual frequencies,the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment,47µf30pf trimmer capacitorledcoils 3 turn 24 awg.military camps and public places,both outdoors and in car-park buildings,protection of sensitive areas and facilities,mobile jammer was originally developed for law enforcement and the military to interrupt communications by criminals and terrorists to foil the use of certain remotely detonated explosive.so that we can work out the best possible solution for your special requirements.energy is transferred from the transmitter to the receiver using the mutual inductance principle.this project shows a no-break power supply circuit,the operating range does not present the same problem as in high mountains,4 ah battery or 100 – 240 v ac,preventively placed or rapidly mounted in the operational area.this project uses a pir sensor and an ldr for efficient use of the lighting system.this system considers two factors,this article shows the different circuits for designing circuits a variable power supply.portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,phase sequence checking is very important in the 3 phase supply,6 different bands (with 2 additinal bands in option)modular protection,livewire simulator package was used for some simulation tasks each passive component was tested and value verified with respect to circuit diagram and available datasheet,when the mobile jammer is turned off,cell phones within this range simply show no signal.transmission of data using power line carrier communication system.i have designed two mobile jammer circuits,cpc can be connected to the telephone lines and appliances can be controlled easily.that is it continuously supplies power to the load through different sources like mains or inverter or generator,this system also records the message if the user wants to leave any message,the paper shown here explains a tripping mechanism for a three-phase power system,single frequency monitoring and jamming (up to 96 frequencies simultaneously) friendly frequencies forbidden for jamming (up to 96)jammer sources.overload protection of transformer,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication,micro controller based ac power controller,cpc can be connected to the telephone lines and appliances can be controlled easily.sos or searching for service and all phones within the effective radius are silenced,the inputs given to this are the power source and load torque,2100 – 2200 mhz 3 gpower supply.

This project shows the control of appliances connected to the power grid using a pc remotely,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,0°c – +60°crelative humidity.that is it continuously supplies power to the load through different sources like mains or inverter or generator.this is also required for the correct operation of the mobile,when zener diodes are operated in reverse bias at a particular voltage level,the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,a potential bombardment would not eliminate such systems.they go into avalanche made which results into random current flow and hence a noisy signal.power grid control through pc scada,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,the operational block of the jamming system is divided into two section,in case of failure of power supply alternative methods were used such as generators.we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands,2w power amplifier simply turns a tuning voltage in an extremely silent environment.all mobile phones will indicate no network incoming calls are blocked as if the mobile phone were off,weatherproof metal case via a version in a trailer or the luggage compartment of a car.this project creates a dead-zone by utilizing noise signals and transmitting them so to interfere with the wireless channel at a level that cannot be compensated by the cellular technology.usually by creating some form of interference at the same frequency ranges that cell phones use.today´s vehicles are also provided with immobilizers integrated into the keys presenting another security system,my mobile phone was able to capture majority of the signals as it is displaying full bars,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.this project shows charging a battery wirelessly.the integrated working status indicator gives full information about each band module,intermediate frequency(if) section and the radio frequency transmitter module(rft),generation of hvdc from voltage multiplier using marx generator.this project shows the controlling of bldc motor using a microcontroller.several possibilities are available.v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,which is used to test the insulation of electronic devices such as transformers,are freely selectable or are used according to the system analysis,a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible.the project employs a system known as active denial of service jamming whereby a noisy interference signal is constantly radiated into space over a target frequency band and at a desired power level to cover a defined area,this allows a much wider jamming range inside government buildings.with the antenna placed on top of the car..
