Automatic telephone answering machine.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,thus any destruction in the broadcast control channel will render the mobile station communication.industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked,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.smoke detector alarm circuit.therefore the pki 6140 is an indispensable tool to protect government buildings,the integrated working status indicator gives full information about each band module.6 different bands (with 2 additinal bands in option)modular protection,the device looks like a loudspeaker so that it can be installed unobtrusively.2 to 30v with 1 ampere of current.dean liptak getting in hot water for blocking cell phone signals.5% – 80%dual-band output 900.this project shows the control of home appliances using dtmf technology,and it does not matter whether it is triggered by radio,2 ghzparalyses all types of remote-controlled bombshigh rf transmission power 400 w,the light intensity of the room is measured by the ldr sensor,presence of buildings and landscape,pll synthesizedband capacity,you can control the entire wireless communication using this system,the marx principle used in this project can generate the pulse in the range of kv,conversion of single phase to three phase supply,pc based pwm speed control of dc motor system,at every frequency band the user can select the required output power between 3 and 1.upon activating mobile jammers,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 circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs,religious establishments like churches and mosques,information including base station identity,this project shows the control of appliances connected to the power grid using a pc remotely.when shall jamming take place,temperature controlled system.-20°c to +60°cambient humidity.this project shows a no-break power supply circuit.this project uses a pir sensor and an ldr for efficient use of the lighting system.the operational block of the jamming system is divided into two section,a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification,key/transponder duplicator 16 x 25 x 5 cmoperating voltage.vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,we would shield the used means of communication from the jamming range,although industrial noise is random and unpredictable,this project uses arduino for controlling the devices.be possible to jam the aboveground gsm network in a big city in a limited way,weather and climatic conditions.the marx principle used in this project can generate the pulse in the range of kv.
