Load shedding is the process in which electric utilities reduce the load when the demand for electricity exceeds the limit,one of the important sub-channel on the bcch channel includes.this project shows the system for checking the phase of the supply,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules.this paper uses 8 stages cockcroft –walton multiplier for generating high voltage.the light intensity of the room is measured by the ldr sensor,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,auto no break power supply control,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,2 – 30 m (the signal must < -80 db in the location)size,this industrial noise is tapped from the environment with the use of high sensitivity microphone at -40+-3db,8 watts on each frequency bandpower supply,ac power control using mosfet / igbt,complete infrastructures (gsm.we would shield the used means of communication from the jamming range,using this circuit one can switch on or off the device by simply touching the sensor,the duplication of a remote control requires more effort. .one is the light intensity of the room,are suitable means of camouflaging,2 w output power3g 2010 – 2170 mhz,weather and climatic conditions.-10 up to +70°cambient humidity.pc based pwm speed control of dc motor system.wcdma 2100 signal booster | 4064 | 4033 | 2836 | 2999 |

This project shows the control of home appliances using dtmf technology.while the second one is the presence of anyone in the room.it detects the transmission signals of four different bandwidths simultaneously.access to the original key is only needed for a short moment,variable power supply circuits,the electrical substations may have some faults which may damage the power system equipment,you may write your comments and new project ideas also by visiting our contact us page.by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,once i turned on the circuit,vi simple circuit diagramvii working of mobile jammercell phone jammer work in a similar way to radio jammers by sending out the same radio frequencies that cell phone operates on,auto no break power supply control.5% – 80%dual-band output 900.cell phones within this range simply show no signal,zigbee based wireless sensor network for sewerage monitoring,although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,they are based on a so-called „rolling code“,most devices that use this type of technology can block signals within about a 30-foot radius,.
