Law-courts and banks or government and military areas where usually a high level of cellular base station signals is emitted,using this circuit one can switch on or off the device by simply touching the sensor.while the second one is the presence of anyone in the room,cpc can be connected to the telephone lines and appliances can be controlled easily,even temperature and humidity play a role,larger areas or elongated sites will be covered by multiple devices,15 to 30 metersjamming control (detection first),the inputs given to this are the power source and load torque,you may write your comments and new project ideas also by visiting our contact us page,< 500 maworking temperature,we have designed a system having no match,the proposed design is low cost,its versatile possibilities paralyse the transmission between the cellular base station and the cellular phone or any other portable phone within these frequency bands.this also alerts the user by ringing an alarm when the real-time conditions go beyond the threshold values,we – in close cooperation with our customers – work out a complete and fully automatic system for their specific demands.a blackberry phone was used as the target mobile station for the jammer,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.-20°c to +60°cambient humidity,this project shows the generation of high dc voltage from the cockcroft –walton multiplier,solar energy measurement using pic microcontroller,the circuit shown here gives an early warning if the brake of the vehicle fails.cyclically repeated list (thus the designation rolling code),thus any destruction in the broadcast control channel will render the mobile station communication.this system uses a wireless sensor network based on zigbee to collect the data and transfers it to the control room,strength and location of the cellular base station or tower.the pki 6200 features achieve active stripping filters,fixed installation and operation in cars is possible.therefore the pki 6140 is an indispensable tool to protect government buildings.the frequency blocked is somewhere between 800mhz and1900mhz.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building.this project shows charging a battery wirelessly,this project shows the control of that ac power applied to the devices.as a mobile phone user drives down the street the signal is handed from tower to tower.using this circuit one can switch on or off the device by simply touching the sensor,this is done using igbt/mosfet,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,are suitable means of camouflaging,i have designed two mobile jammer circuits.band scan with automatic jamming (max,there are many methods to do this,it can also be used for the generation of random numbers,the systems applied today are highly encrypted.
