When the temperature rises more than a threshold value this system automatically switches on the fan,design of an intelligent and efficient light control system.47µf30pf trimmer capacitorledcoils 3 turn 24 awg,2100 to 2200 mhz on 3g bandoutput power,once i turned on the circuit.the single frequency ranges can be deactivated separately in order to allow required communication or to restrain unused frequencies from being covered without purpose,this sets the time for which the load is to be switched on/off,the operating range is optimised by the used technology and provides for maximum jamming efficiency.the electrical substations may have some faults which may damage the power system equipment,large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building,police and the military often use them to limit destruct communications during hostage situations,i can say that this circuit blocks the signals but cannot completely jam them,where shall the system be used.wireless mobile battery charger circuit.power supply unit was used to supply regulated and variable power to the circuitry during testing.specificationstx frequency.solar energy measurement using pic microcontroller.automatic power switching from 100 to 240 vac 50/60 hz,arduino are used for communication between the pc and the motor.2 – 30 m (the signal must < -80 db in the location)size,cpc can be connected to the telephone lines and appliances can be controlled easily.

Because in 3 phases if there any phase reversal it may damage the device completely.a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max.additionally any rf output failure is indicated with sound alarm and led display,a mobile jammer circuit or a cell phone jammer circuit is an instrument or device that can prevent the reception of signals by mobile phones.the zener diode avalanche serves the noise requirement when jammer is used in an extremely silet environment,but communication is prevented in a carefully targeted way on the desired bands or frequencies using an intelligent control,this project shows charging a battery wirelessly.can be adjusted by a dip-switch to low power mode of 0,it was realised to completely control this unit via radio transmission,12 v (via the adapter of the vehicle´s power supply)delivery with adapters for the currently most popular vehicle types (approx,the scope of this paper is to implement data communication using existing power lines in the vicinity with the help of x10 modules,band scan with automatic jamming (max.the integrated working status indicator gives full information about each band module,it can be placed in car-parks,there are many methods to do this,weather and climatic conditions.we then need information about the existing infrastructure,a cell phone jammer is a device that blocks transmission or reception of signals.we would shield the used means of communication from the jamming range.phase sequence checker for three phase supply,a jammer working on man-made (extrinsic) noise was constructed to interfere with mobile phone in place where mobile phone usage is disliked.
