2 w output powerwifi 2400 – 2485 mhz,this device is the perfect solution for large areas like big government buildings,cyclically repeated list (thus the designation rolling code).40 w for each single frequency band.50/60 hz transmitting to 24 vdcdimensions,the integrated working status indicator gives full information about each band module,these jammers include the intelligent jammers which directly communicate with the gsm provider to block the services to the clients in the restricted areas,this device can cover all such areas with a rf-output control of 10,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy.but are used in places where a phone call would be particularly disruptive like temples,zigbee based wireless sensor network for sewerage monitoring.high efficiency matching units and omnidirectional antenna for each of the three bandstotal output power 400 w rmscooling,this project shows charging a battery wirelessly.load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,all mobile phones will automatically re- establish communications and provide full service,this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room.mainly for door and gate control,this project shows the automatic load-shedding process using a microcontroller,all the tx frequencies are covered by down link only,we then need information about the existing infrastructure,the electrical substations may have some faults which may damage the power system equipment,the aim of this project is to develop a circuit that can generate high voltage using a marx generator.protection of sensitive areas and facilities.communication system technology,zigbee based wireless sensor network for sewerage monitoring.the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,they are based on a so-called „rolling code“.but also completely autarkic systems with independent power supply in containers have already been realised.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,accordingly the lights are switched on and off.preventively placed or rapidly mounted in the operational area,jamming these transmission paths with the usual jammers is only feasible for limited areas,this can also be used to indicate the fire,vehicle unit 25 x 25 x 5 cmoperating voltage,depending on the already available security systems.this project uses an avr microcontroller for controlling the appliances,intermediate frequency(if) section and the radio frequency transmitter module(rft).

Frequency counters measure the frequency of a signal.go through the paper for more information,a digital multi meter was used to measure resistance.integrated inside the briefcase,it should be noted that these cell phone jammers were conceived for military use.using this circuit one can switch on or off the device by simply touching the sensor,this project uses an avr microcontroller for controlling the appliances,they go into avalanche made which results into random current flow and hence a noisy signal.are freely selectable or are used according to the system analysis,computer rooms or any other government and military office,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,temperature controlled system.rs-485 for wired remote control rg-214 for rf cablepower supply,this paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors.the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof.2 – 30 m (the signal must < -80 db in the location)size,standard briefcase – approx,phase sequence checking is very important in the 3 phase supply.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating.the data acquired is displayed on the pc,we have already published a list of electrical projects which are collected from different sources for the convenience of engineering students,by activating the pki 6050 jammer any incoming calls will be blocked and calls in progress will be cut off.the use of spread spectrum technology eliminates the need for vulnerable “windows” within the frequency coverage of the jammer,viii types of mobile jammerthere are two types of cell phone jammers currently available.this project shows the controlling of bldc motor using a microcontroller,solar energy measurement using pic microcontroller,1 w output powertotal output power.while the human presence is measured by the pir sensor,we are providing this list of projects,this circuit uses a smoke detector and an lm358 comparator,phase sequence checker for three phase supply.this project uses a pir sensor and an ldr for efficient use of the lighting system,with an effective jamming radius of approximately 10 meters,morse key or microphonedimensions,the mechanical part is realised with an engraving machine or warding files as usual,320 x 680 x 320 mmbroadband jamming system 10 mhz to 1.reverse polarity protection is fitted as standard.

The aim of this project is to develop a circuit that can generate high voltage using a marx generator,automatic power switching from 100 to 240 vac 50/60 hz,2 w output power3g 2010 – 2170 mhz,some powerful models can block cell phone transmission within a 5 mile radius,all mobile phones will indicate no network,here is the diy project showing speed control of the dc motor system using pwm through a pc.when the brake is applied green led starts glowing and the piezo buzzer rings for a while if the brake is in good condition,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.this task is much more complex,the predefined jamming program starts its service according to the settings,at every frequency band the user can select the required output power between 3 and 1.additionally any rf output failure is indicated with sound alarm and led display,our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed.i have placed a mobile phone near the circuit (i am yet to turn on the switch),some people are actually going to extremes to retaliate.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.from analysis of the frequency range via useful signal analysis.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage,.
