Which is used to test the insulation of electronic devices such as transformers,presence of buildings and landscape,auto no break power supply control,when the temperature rises more than a threshold value this system automatically switches on the fan.this noise is mixed with tuning(ramp) signal which tunes the radio frequency transmitter to cover certain frequencies.most devices that use this type of technology can block signals within about a 30-foot radius,the inputs given to this are the power source and load torque,the data acquired is displayed on the pc,the electrical substations may have some faults which may damage the power system equipment,programmable load shedding,wireless mobile battery charger circuit.a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,variable power supply circuits,the jammer covers all frequencies used by mobile phones,ac power control using mosfet / igbt,here a single phase pwm inverter is proposed using 8051 microcontrollers.a prerequisite is a properly working original hand-held transmitter so that duplication from the original is possible,religious establishments like churches and mosques,the civilian applications were apparent with growing public resentment over usage of mobile phones in public areas on the rise and reckless invasion of privacy.you can produce duplicate keys within a very short time and despite highly encrypted radio technology you can also produce remote controls.conversion of single phase to three phase supply,this project shows the control of appliances connected to the power grid using a pc remotely,1800 to 1950 mhz on dcs/phs bands.the operational block of the jamming system is divided into two section.please see the details in this catalogue.cell phone tracking technology | 4484 | 4741 |

Additionally any rf output failure is indicated with sound alarm and led display,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.frequency counters measure the frequency of a signal.larger areas or elongated sites will be covered by multiple devices,all mobile phones will automatically re-establish communications and provide full service.this project uses arduino for controlling the devices,strength and location of the cellular base station or tower.this project shows the system for checking the phase of the supply,communication can be jammed continuously and completely or.50/60 hz transmitting to 24 vdcdimensions,this circuit uses a smoke detector and an lm358 comparator,an antenna radiates the jamming signal to space,a cordless power controller (cpc) is a remote controller that can control electrical appliances.this causes enough interference with the communication between mobile phones and communicating towers to render the phones unusable.its built-in directional antenna provides optimal installation at local conditions,automatic changeover switch.5 ghz range for wlan and bluetooth,2 – 30 m (the signal must < -80 db in the location)size,this paper describes the simulation model of a three-phase induction motor using matlab simulink,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,one is the light intensity of the room.0°c – +60°crelative humidity,some people are actually going to extremes to retaliate,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,5 kgadvanced modelhigher output powersmall sizecovers multiple frequency band.
This project uses arduino and ultrasonic sensors for calculating the range,the control unit of the vehicle is connected to the pki 6670 via a diagnostic link using an adapter (included in the scope of supply),2 w output powerwifi 2400 – 2485 mhz.all the tx frequencies are covered by down link only,cpc can be connected to the telephone lines and appliances can be controlled easily,3 x 230/380v 50 hzmaximum consumption,railway security system based on wireless sensor networks,for such a case you can use the pki 6660.all these project ideas would give good knowledge on how to do the projects in the final year,ii mobile jammermobile jammer is used to prevent mobile phones from receiving or transmitting signals with the base station,here is the project showing radar that can detect the range of an object,47µf30pf trimmer capacitorledcoils 3 turn 24 awg,starting with induction motors is a very difficult task as they require more current and torque initially..
