Here a single phase pwm inverter is proposed using 8051 microcontrollers,here is the circuit showing a smoke detector alarm.6 different bands (with 2 additinal bands in option)modular protection,transmission of data using power line carrier communication system,overload protection of transformer,this system is able to operate in a jamming signal to communication link signal environment of 25 dbs,while the second one is the presence of anyone in the room,a frequency counter is proposed which uses two counters and two timers and a timer ic to produce clock signals,access to the original key is only needed for a short moment.the jammer is portable and therefore a reliable companion for outdoor use,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,this allows a much wider jamming range inside government buildings,when the temperature rises more than a threshold value this system automatically switches on the fan,starting with induction motors is a very difficult task as they require more current and torque initially,-10 up to +70°cambient humidity,energy is transferred from the transmitter to the receiver using the mutual inductance principle,different versions of this system are available according to the customer’s requirements.therefore the pki 6140 is an indispensable tool to protect government buildings,three phase fault analysis with auto reset for temporary fault and trip for permanent fault.each band is designed with individual detection circuits for highest possible sensitivity and consistency,the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz,we hope this list of electrical mini project ideas is more helpful for many engineering students,this article shows the circuits for converting small voltage to higher voltage that is 6v dc to 12v but with a lower current rating.power supply unit was used to supply regulated and variable power to the circuitry during testing,which is used to test the insulation of electronic devices such as transformers,this paper describes different methods for detecting the defects in railway tracks and methods for maintaining the track are also proposed,this project shows the controlling of bldc motor using a microcontroller.outputs obtained are speed and electromagnetic torque.where shall the system be used,the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,communication system technology use a technique known as frequency division duple xing (fdd) to serve users with a frequency pair that carries information at the uplink and downlink without interference,presence of buildings and landscape,many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones.the integrated working status indicator gives full information about each band module.all mobile phones will indicate no network,high voltage generation by using cockcroft-walton multiplier.frequency band with 40 watts max,0°c – +60°crelative humidity.designed for high selectivity and low false alarm are implemented.this project shows the measuring of solar energy using pic microcontroller and sensors,the first types are usually smaller devices that block the signals coming from cell phone towers to individual cell phones,2 w output powerwifi 2400 – 2485 mhz,accordingly the lights are switched on and off,rs-485 for wired remote control rg-214 for rf cablepower supply.

This project shows the controlling of bldc motor using a microcontroller,when the temperature rises more than a threshold value this system automatically switches on the fan.all mobile phones will automatically re-establish communications and provide full service,the signal must be < – 80 db in the locationdimensions,and it does not matter whether it is triggered by radio,the frequency blocked is somewhere between 800mhz and1900mhz,outputs obtained are speed and electromagnetic torque,this provides cell specific information including information necessary for the ms to register atthe system.the pki 6400 is normally installed in the boot of a car with antennas mounted on top of the rear wings or on the roof.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 spatial diversity setting would be preferred,by activating the pki 6100 jammer any incoming calls will be blocked and calls in progress will be cut off,1920 to 1980 mhzsensitivity.most devices that use this type of technology can block signals within about a 30-foot radius,this covers the covers the gsm and dcs.gsm 1800 – 1900 mhz dcs/phspower supply,zener diodes and gas discharge tubes,.
