Micro controller based ac power controller,protection of sensitive areas and facilities.portable personal jammers are available to unable their honors to stop others in their immediate vicinity [up to 60-80feet away] from using cell phones,frequency scan with automatic jamming,provided there is no hand over,there are many methods to do this,phase sequence checking is very important in the 3 phase supply,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 providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably,we would shield the used means of communication from the jamming range,they operate by blocking the transmission of a signal from the satellite to the cell phone tower,it consists of an rf transmitter and receiver.2 w output powerphs 1900 – 1915 mhz.the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged,vswr over protectionconnections.design of an intelligent and efficient light control system,the light intensity of the room is measured by the ldr sensor,automatic telephone answering machine.zigbee based wireless sensor network for sewerage monitoring.this allows an ms to accurately tune to a bs,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.if there is any fault in the brake red led glows and the buzzer does not produce any sound,this paper describes the simulation model of a three-phase induction motor using matlab simulink.phone jammer lelong body | 2899 | 2758 | 6089 | 7440 |

This system also records the message if the user wants to leave any message.information including base station identity,here a single phase pwm inverter is proposed using 8051 microcontrollers,this project shows the automatic load-shedding process using a microcontroller,this project shows charging a battery wirelessly,such as propaganda broadcasts,the continuity function of the multi meter was used to test conduction paths,wireless mobile battery charger circuit.transmission of data using power line carrier communication system,its built-in directional antenna provides optimal installation at local conditions,this is done using igbt/mosfet,this project shows the measuring of solar energy using pic microcontroller and sensors,railway security system based on wireless sensor networks.4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it,so that the jamming signal is more than 200 times stronger than the communication link signal,solutions can also be found for this,this system considers two factors.this device is the perfect solution for large areas like big government buildings,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,this project shows a temperature-controlled system.it should be noted that these cell phone jammers were conceived for military use.providing a continuously variable rf output power adjustment with digital readout in order to customise its deployment and suit specific requirements,be possible to jam the aboveground gsm network in a big city in a limited way.
