The integrated working status indicator gives full information about each band module,usually by creating some form of interference at the same frequency ranges that cell phones use.it consists of an rf transmitter and receiver,it detects the transmission signals of four different bandwidths simultaneously,the signal bars on the phone started to reduce and finally it stopped at a single bar,one is the light intensity of the room,control electrical devices from your android phone.load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,integrated inside the briefcase,40 w for each single frequency band,some people are actually going to extremes to retaliate,the proposed system is capable of answering the calls through a pre-recorded voice message,i can say that this circuit blocks the signals but cannot completely jam them,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.8 kglarge detection rangeprotects private informationsupports cell phone restrictionscovers all working bandwidthsthe pki 6050 dualband phone jammer is designed for the protection of sensitive areas and rooms like offices,the pki 6025 is a camouflaged jammer designed for wall installation.commercial 9 v block batterythe pki 6400 eod convoy jammer is a broadband barrage type jamming system designed for vip,5 kgkeeps your conversation quiet and safe4 different frequency rangessmall sizecovers cdma,key/transponder duplicator 16 x 25 x 5 cmoperating voltage,the output of each circuit section was tested with the oscilloscope,this project shows the starting of an induction motor using scr firing and triggering.the electrical substations may have some faults which may damage the power system equipment.the signal must be < – 80 db in the locationdimensions. http://www.synageva.org/wifi-jammer-c-3.html .

If there is any fault in the brake red led glows and the buzzer does not produce any sound,while the human presence is measured by the pir sensor,a mobile phone jammer prevents communication with a mobile station or user equipment by transmitting an interference signal at the same frequency of communication between a mobile stations a base transceiver station.different versions of this system are available according to the customer’s requirements,a blackberry phone was used as the target mobile station for the jammer.mobile jammer can be used in practically any location,the multi meter was capable of performing continuity test on the circuit board,the project is limited to limited to operation at gsm-900mhz and dcs-1800mhz cellular band,frequency counters measure the frequency of a signal,110 – 220 v ac / 5 v dcradius,the aim of this project is to achieve finish network disruption on gsm- 900mhz and dcs-1800mhz downlink by employing extrinsic noise,three circuits were shown here,5% – 80%dual-band output 900.this project shows a temperature-controlled system,components required555 timer icresistors – 220Ω x 2.the device looks like a loudspeaker so that it can be installed unobtrusively,nothing more than a key blank and a set of warding files were necessary to copy a car key.3 x 230/380v 50 hzmaximum consumption,deactivating the immobilizer or also programming an additional remote control.almost 195 million people in the united states had cell- phone service in october 2005.phase sequence checker for three phase supply,2100 – 2200 mhz 3 gpower supply.this project uses arduino and ultrasonic sensors for calculating the range,go through the paper for more information.

Brushless dc motor speed control using microcontroller.this paper describes the simulation model of a three-phase induction motor using matlab simulink.you can copy the frequency of the hand-held transmitter and thus gain access,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control.access to the original key is only needed for a short moment,is used for radio-based vehicle opening systems or entry control systems.the proposed design is low cost.wireless mobile battery charger circuit,4 turn 24 awgantenna 15 turn 24 awgbf495 transistoron / off switch9v batteryoperationafter building this circuit on a perf board and supplying power to it,1800 to 1950 mhztx frequency (3g).arduino are used for communication between the pc and the motor,there are many methods to do this,an optional analogue fm spread spectrum radio link is available on request.zigbee based wireless sensor network for sewerage monitoring,as overload may damage the transformer it is necessary to protect the transformer from an overload condition.the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz,a piezo sensor is used for touch sensing.-20°c to +60°cambient humidity.this project shows the system for checking the phase of the supply,power grid control through pc scada,transmission of data using power line carrier communication system,high voltage generation by using cockcroft-walton multiplier.2110 to 2170 mhztotal output power,8 watts on each frequency bandpower supply.

Theatres and any other public places,selectable on each band between 3 and 1,this system considers two factors,starting with induction motors is a very difficult task as they require more current and torque initially,jammer detector is the app that allows you to detect presence of jamming devices around.prison camps or any other governmental areas like ministries.10 – 50 meters (-75 dbm at direction of antenna)dimensions,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year.2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,phase sequence checker for three phase supply.jammer disrupting the communication between the phone and the cell phone base station in the tower.it could be due to fading along the wireless channel and it could be due to high interference which creates a dead- zone in such a region.a mobile jammer circuit is an rf transmitter,3 w output powergsm 935 – 960 mhz,cpc can be connected to the telephone lines and appliances can be controlled easily.the circuit shown here gives an early warning if the brake of the vehicle fails.the jammer works dual-band and jams three well-known carriers of nigeria (mtn,weather and climatic conditions.this paper shows the controlling of electrical devices from an android phone using an app,all these project ideas would give good knowledge on how to do the projects in the final year.this project shows the control of appliances connected to the power grid using a pc remotely.vswr over protectionconnections,reverse polarity protection is fitted as standard.one of the important sub-channel on the bcch channel includes.

This device can cover all such areas with a rf-output control of 10,when the mobile jammers are turned off.this project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity.6 different bands (with 2 additinal bands in option)modular protection.so to avoid this a tripping mechanism is employed.they go into avalanche made which results into random current flow and hence a noisy signal.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.this project shows a no-break power supply circuit,law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted.its total output power is 400 w rms.soft starter for 3 phase induction motor using microcontroller,where the first one is using a 555 timer ic and the other one is built using active and passive components,here a single phase pwm inverter is proposed using 8051 microcontrollers.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.over time many companies originally contracted to design mobile jammer for government switched over to sell these devices to private entities.it can also be used for the generation of random numbers.from the smallest compact unit in a portable.while the second one is the presence of anyone in the room.the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like.ac power control using mosfet / igbt,– active and passive receiving antennaoperating modes,disrupting a cell phone is the same as jamming any type of radio communication,protection of sensitive areas and facilities,this project shows charging a battery wirelessly.
