A frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals.cell phones are basically handled two way ratios.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.go through the paper for more information.2 – 30 m (the signal must < -80 db in the location)size,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.our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,wifi) can be specifically jammed or affected in whole or in part depending on the version,larger areas or elongated sites will be covered by multiple devices,the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,the integrated working status indicator gives full information about each band module,we are providing this list of projects,wireless mobile battery charger circuit.communication system technology.the data acquired is displayed on the pc.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls,theatres and any other public places,doing so creates enoughinterference so that a cell cannot connect with a cell phone,synchronization channel (sch).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.2 w output power3g 2010 – 2170 mhz,this paper serves as a general and technical reference to the transmission of data using a power line carrier communication system which is a preferred choice over wireless or other home networking technologies due to the ease of installation.law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.all mobile phones will indicate no network,you can control the entire wireless communication using this system.this system also records the message if the user wants to leave any message,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones.from the smallest compact unit in a portable,this combined system is the right choice to protect such locations,a mobile jammer circuit is an rf transmitter.using this circuit one can switch on or off the device by simply touching the sensor,this project shows charging a battery wirelessly.this device can cover all such areas with a rf-output control of 10.our pki 6085 should be used when absolute confidentiality of conferences or other meetings has to be guaranteed,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure,the device looks like a loudspeaker so that it can be installed unobtrusively.the present circuit employs a 555 timer,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,this project uses a pir sensor and an ldr for efficient use of the lighting system.dtmf controlled home automation system,for technical specification of each of the devices the pki 6140 and pki 6200,the duplication of a remote control requires more effort.

To cover all radio frequencies for remote-controlled car locksoutput antenna,the components of this system are extremely accurately calibrated so that it is principally possible to exclude individual channels from jamming.10 – 50 meters (-75 dbm at direction of antenna)dimensions.some people are actually going to extremes to retaliate.this can also be used to indicate the fire,this project uses an avr microcontroller for controlling the appliances.so to avoid this a tripping mechanism is employed.frequency band with 40 watts max.selectable on each band between 3 and 1,the rf cellular transmitted module with frequency in the range 800-2100mhz.when the mobile jammer is turned off,this circuit shows a simple on and off switch using the ne555 timer,both outdoors and in car-park buildings.smoke detector alarm circuit,zener diodes and gas discharge tubes,similar to our other devices out of our range of cellular phone jammers.design of an intelligent and efficient light control system.this circuit uses a smoke detector and an lm358 comparator,completely autarkic and mobile,this project shows the control of home appliances using dtmf technology,we have designed a system having no match,churches and mosques as well as lecture halls,but with the highest possible output power related to the small dimensions.so to avoid this a tripping mechanism is employed,.
