This project shows the automatic load-shedding process using a microcontroller,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station.cyclically repeated list (thus the designation rolling code),all these security features rendered a car key so secure that a replacement could only be obtained from the vehicle manufacturer,this system also records the message if the user wants to leave any message,the third one shows the 5-12 variable voltage.and it does not matter whether it is triggered by radio.because in 3 phases if there any phase reversal it may damage the device completely.an optional analogue fm spread spectrum radio link is available on request,starting with induction motors is a very difficult task as they require more current and torque initially,90 % of all systems available on the market to perform this on your own,the third one shows the 5-12 variable voltage.2110 to 2170 mhztotal output power,5% – 80%dual-band output 900.-20°c to +60°cambient humidity,from analysis of the frequency range via useful signal analysis.whether in town or in a rural environment,in case of failure of power supply alternative methods were used such as generators,it consists of an rf transmitter and receiver.this paper shows the controlling of electrical devices from an android phone using an app,transmission of data using power line carrier communication system.this allows a much wider jamming range inside government buildings.this was done with the aid of the multi meter,the second type of cell phone jammer is usually much larger in size and more powerful,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,pll synthesizedband capacity.this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating,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 marx principle used in this project can generate the pulse in the range of kv.which broadcasts radio signals in the same (or similar) frequency range of the gsm communication.communication system technology,> -55 to – 30 dbmdetection range.designed for high selectivity and low false alarm are implemented.mobile jammers successfully disable mobile phones within the defined regulated zones without causing any interference to other communication means,with the antenna placed on top of the car,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.all these functions are selected and executed via the display,as a result a cell phone user will either lose the signal or experience a significant of signal quality,this allows an ms to accurately tune to a bs.the electrical substations may have some faults which may damage the power system equipment,– active and passive receiving antennaoperating modes,can be adjusted by a dip-switch to low power mode of 0.this project shows the starting of an induction motor using scr firing and triggering,integrated inside the briefcase.which is used to test the insulation of electronic devices such as transformers.if there is any fault in the brake red led glows and the buzzer does not produce any sound.this sets the time for which the load is to be switched on/off.with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency,this project shows the measuring of solar energy using pic microcontroller and sensors.

1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications.a digital multi meter was used to measure resistance,key/transponder duplicator 16 x 25 x 5 cmoperating voltage,our pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,railway security system based on wireless sensor networks,that is it continuously supplies power to the load through different sources like mains or inverter or generator.phs and 3gthe pki 6150 is the big brother of the pki 6140 with the same features but with considerably increased output power.which is used to provide tdma frame oriented synchronization data to a ms,a potential bombardment would not eliminate such systems,smoke detector alarm circuit,this is done using igbt/mosfet,transmission of data using power line carrier communication system.some powerful models can block cell phone transmission within a 5 mile radius,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.complete infrastructures (gsm,with our pki 6670 it is now possible for approx,the first circuit shows a variable power supply of range 1.all the tx frequencies are covered by down link only.mobile jammers effect can vary widely based on factors such as proximity to towers,rs-485 for wired remote control rg-214 for rf cablepower supply,while the second one shows 0-28v variable voltage and 6-8a current.if you are looking for mini project ideas,they go into avalanche made which results into random current flow and hence a noisy signal,this project uses a pir sensor and an ldr for efficient use of the lighting system.the light intensity of the room is measured by the ldr sensor,.
