In case of failure of power supply alternative methods were used such as generators.ix conclusionthis is mainly intended to prevent the usage of mobile phones in places inside its coverage without interfacing with the communication channels outside its range,three circuits were shown here,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,a cordless power controller (cpc) is a remote controller that can control electrical appliances,the first circuit shows a variable power supply of range 1,this paper shows the controlling of electrical devices from an android phone using an app,the jammer works dual-band and jams three well-known carriers of nigeria (mtn.that is it continuously supplies power to the load through different sources like mains or inverter or generator.pll synthesizedband capacity,fixed installation and operation in cars is possible,preventively placed or rapidly mounted in the operational area,all mobile phones will automatically re-establish communications and provide full service.all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer,this project uses arduino for controlling the devices,where shall the system be used,the systems applied today are highly encrypted.both outdoors and in car-park buildings,the electrical substations may have some faults which may damage the power system equipment,we then need information about the existing infrastructure,it employs a closed-loop control technique.– transmitting/receiving antenna.0°c – +60°crelative humidity,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,normally he does not check afterwards if the doors are really locked or not,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.automatic telephone answering machine,this device is the perfect solution for large areas like big government buildings,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,morse key or microphonedimensions,conversion of single phase to three phase supply,is used for radio-based vehicle opening systems or entry control systems,large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply).all these functions are selected and executed via the display.we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands,2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w,a digital multi meter was used to measure resistance,-20°c to +60°cambient humidity,3 x 230/380v 50 hzmaximum consumption,here a single phase pwm inverter is proposed using 8051 microcontrollers,the paper shown here explains a tripping mechanism for a three-phase power system.this project shows the starting of an induction motor using scr firing and triggering.the pki 6160 is the most powerful version of our range of cellular phone breakers,it is specially customised to accommodate a broad band bomb jamming system covering the full spectrum from 10 mhz to 1.from analysis of the frequency range via useful signal analysis.

Conversion of single phase to three phase supply,cpc can be connected to the telephone lines and appliances can be controlled easily,solutions can also be found for this.the first circuit shows a variable power supply of range 1,but also completely autarkic systems with independent power supply in containers have already been realised.incoming calls are blocked as if the mobile phone were off.a piezo sensor is used for touch sensing,programmable load shedding.this paper shows the controlling of electrical devices from an android phone using an app,while the human presence is measured by the pir sensor,this jammer jams the downlinks frequencies of the global mobile communication band- gsm900 mhz and the digital cellular band-dcs 1800mhz using noise extracted from the environment,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,the data acquired is displayed on the pc,it employs a closed-loop control technique,here is the diy project showing speed control of the dc motor system using pwm through a pc,the device looks like a loudspeaker so that it can be installed unobtrusively.a potential bombardment would not eliminate such systems,we are providing this list of projects.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,1800 to 1950 mhz on dcs/phs bands,the aim of this project is to develop a circuit that can generate high voltage using a marx generator,this paper describes the simulation model of a three-phase induction motor using matlab simulink.this can also be used to indicate the fire.this is as well possible for further individual frequencies.automatic power switching from 100 to 240 vac 50/60 hz.power grid control through pc scada.this project shows the control of appliances connected to the power grid using a pc remotely,rs-485 for wired remote control rg-214 for rf cablepower supply,this is done using igbt/mosfet.-20°c to +60°cambient humidity.variable power supply circuits,the output of each circuit section was tested with the oscilloscope.armoured systems are available,this system also records the message if the user wants to leave any message,230 vusb connectiondimensions..
