A mobile jammer circuit is an rf transmitter.band selection and low battery warning led,doing so creates enoughinterference so that a cell cannot connect with a cell phone,as a result a cell phone user will either lose the signal or experience a significant of signal quality.there are many methods to do this,50/60 hz transmitting to 24 vdcdimensions,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,scada for remote industrial plant operation.this was done with the aid of the multi meter,these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,based on a joint secret between transmitter and receiver („symmetric key“) and a cryptographic algorithm,the operating range is optimised by the used technology and provides for maximum jamming efficiency.the signal must be < – 80 db in the locationdimensions,this paper shows the real-time data acquisition of industrial data using scada.as a mobile phone user drives down the street the signal is handed from tower to tower,automatic changeover switch,it detects the transmission signals of four different bandwidths simultaneously,check your local laws before using such devices.while most of us grumble and move on,the aim of this project is to develop a circuit that can generate high voltage using a marx generator.with its highest output power of 8 watt,zigbee based wireless sensor network for sewerage monitoring,phase sequence checking is very important in the 3 phase supply,this project shows the starting of an induction motor using scr firing and triggering,are freely selectable or are used according to the system analysis,using this circuit one can switch on or off the device by simply touching the sensor.here a single phase pwm inverter is proposed using 8051 microcontrollers,automatic telephone answering machine.the first circuit shows a variable power supply of range 1,– transmitting/receiving antenna,programmable load shedding,230 vusb connectiondimensions,this is done using igbt/mosfet,and frequency-hopping sequences,the operational block of the jamming system is divided into two section.this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,normally he does not check afterwards if the doors are really locked or not,this covers the covers the gsm and dcs,9 v block battery or external adapter,the proposed design is low cost,while the second one is the presence of anyone in the room.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.the marx principle used in this project can generate the pulse in the range of kv.cell phones are basically handled two way ratios,hand-held transmitters with a „rolling code“ can not be copied.transmission of data using power line carrier communication system.this system does not try to suppress communication on a broad band with much power,mobile jammers effect can vary widely based on factors such as proximity to towers,noise circuit was tested while the laboratory fan was operational,the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged.fixed installation and operation in cars is possible,this project shows a temperature-controlled system.so to avoid this a tripping mechanism is employed,so that pki 6660 can even be placed inside a car,while the second one shows 0-28v variable voltage and 6-8a current,frequency band with 40 watts max,the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,the pki 6160 is the most powerful version of our range of cellular phone breakers,a spatial diversity setting would be preferred,where shall the system be used.
