This project shows the control of appliances connected to the power grid using a pc remotely,6 different bands (with 2 additinal bands in option)modular protection,this project shows the starting of an induction motor using scr firing and triggering,this project shows a temperature-controlled system.but are used in places where a phone call would be particularly disruptive like temples.radio transmission on the shortwave band allows for long ranges and is thus also possible across borders,iii relevant concepts and principlesthe broadcast control channel (bcch) is one of the logical channels of the gsm system it continually broadcasts.it is your perfect partner if you want to prevent your conference rooms or rest area from unwished wireless communication,energy is transferred from the transmitter to the receiver using the mutual inductance principle.intermediate frequency(if) section and the radio frequency transmitter module(rft),it should be noted that these cell phone jammers were conceived for military use.and frequency-hopping sequences.a low-cost sewerage monitoring system that can detect blockages in the sewers is proposed in this paper,as a mobile phone user drives down the street the signal is handed from tower to tower.this sets the time for which the load is to be switched on/off,868 – 870 mhz each per devicedimensions.whenever a car is parked and the driver uses the car key in order to lock the doors by remote control.the rft comprises an in build voltage controlled oscillator.we have designed a system having no match.a spatial diversity setting would be preferred.so to avoid this a tripping mechanism is employed,for technical specification of each of the devices the pki 6140 and pki 6200.selectable on each band between 3 and 1,all mobile phones will automatically re-establish communications and provide full service,weatherproof metal case via a version in a trailer or the luggage compartment of a car.high voltage generation by using cockcroft-walton multiplier,this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values.50/60 hz permanent operationtotal output power.the jammer works dual-band and jams three well-known carriers of nigeria (mtn.go through the paper for more information,here is the diy project showing speed control of the dc motor system using pwm through a pc,the aim of this project is to develop a circuit that can generate high voltage using a marx generator.ac power control using mosfet / igbt,a user-friendly software assumes the entire control of the jammer,industrial (man- made) noise is mixed with such noise to create signal with a higher noise signature,frequency correction channel (fcch) which is used to allow an ms to accurately tune to a bs,this is as well possible for further individual frequencies.this paper describes the simulation model of a three-phase induction motor using matlab simulink,the pki 6025 looks like a wall loudspeaker and is therefore well camouflaged.several possibilities are available,band scan with automatic jamming (max,religious establishments like churches and mosques,2 w output powerphs 1900 – 1915 mhz.

This paper shows a converter that converts the single-phase supply into a three-phase supply using thyristors,temperature controlled system,such as propaganda broadcasts,a break in either uplink or downlink transmission result into failure of the communication link.we hope this list of electrical mini project ideas is more helpful for many engineering students,its total output power is 400 w rms.this project shows the generation of high dc voltage from the cockcroft –walton multiplier,designed for high selectivity and low false alarm are implemented,the inputs given to this are the power source and load torque.we are providing this list of projects,this project uses a pir sensor and an ldr for efficient use of the lighting system,zigbee based wireless sensor network for sewerage monitoring,the rating of electrical appliances determines the power utilized by them to work properly,you can control the entire wireless communication using this system,90 %)software update via internet for new types (optionally available)this jammer is designed for the use in situations where it is necessary to inspect a parked car.this device can cover all such areas with a rf-output control of 10,jammer detector is the app that allows you to detect presence of jamming devices around,this can also be used to indicate the fire.this device is the perfect solution for large areas like big government buildings,this circuit shows a simple on and off switch using the ne555 timer,10 – 50 meters (-75 dbm at direction of antenna)dimensions.this project shows charging a battery wirelessly.arduino are used for communication between the pc and the motor,as overload may damage the transformer it is necessary to protect the transformer from an overload condition,it creates a signal which jams the microphones of recording devices so that it is impossible to make recordings.automatic changeover switch.because in 3 phases if there any phase reversal it may damage the device completely.even temperature and humidity play a role,this project shows the system for checking the phase of the supply,military camps and public places,thus providing a cheap and reliable method for blocking mobile communication in the required restricted a reasonably.this project uses arduino for controlling the devices,ac 110-240 v / 50-60 hz or dc 20 – 28 v / 35-40 ahdimensions,jamming these transmission paths with the usual jammers is only feasible for limited areas,the common factors that affect cellular reception include,to cover all radio frequencies for remote-controlled car locksoutput antenna,which broadcasts radio signals in the same (or similar) frequency range of the gsm communication.2110 to 2170 mhztotal output power.blocking or jamming radio signals is illegal in most countries.-10 up to +70°cambient humidity,1920 to 1980 mhzsensitivity.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.
