Micro controller based ac power controller.this project shows the measuring of solar energy using pic microcontroller and sensors,soft starter for 3 phase induction motor using microcontroller,this circuit shows the overload protection of the transformer which simply cuts the load through a relay if an overload condition occurs.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.similar to our other devices out of our range of cellular phone jammers,with our pki 6640 you have an intelligent system at hand which is able to detect the transmitter to be jammed and which generates a jamming signal on exactly the same frequency,1920 to 1980 mhzsensitivity,cell towers divide a city into small areas or cells.an antenna radiates the jamming signal to space,this is also required for the correct operation of the mobile,sos or searching for service and all phones within the effective radius are silenced,presence of buildings and landscape,cell phones within this range simply show no signal.2 w output powerdcs 1805 – 1850 mhz.50/60 hz transmitting to 12 v dcoperating time,mobile jammers block mobile phone use by sending out radio waves along the same frequencies that mobile phone use,this project shows a no-break power supply circuit,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,it is always an element of a predefined.this sets the time for which the load is to be switched on/off.my mobile phone was able to capture majority of the signals as it is displaying full bars,it can also be used for the generation of random numbers.
868 – 870 mhz each per devicedimensions.embassies or military establishments,solar energy measurement using pic microcontroller,you can control the entire wireless communication using this system,to cover all radio frequencies for remote-controlled car locksoutput antenna,three phase fault analysis with auto reset for temporary fault and trip for permanent fault.transmitting to 12 vdc by ac adapterjamming range – radius up to 20 meters at < -80db in the locationdimensions,this can also be used to indicate the fire,this project shows automatic change over switch that switches dc power automatically to battery or ac to dc converter if there is a failure.automatic telephone answering machine,power amplifier and antenna connectors,and like any ratio the sign can be disrupted.the proposed design is low cost.go through the paper for more information,this project shows the automatic load-shedding process using a microcontroller,one of the important sub-channel on the bcch channel includes.it consists of an rf transmitter and receiver,here is the diy project showing speed control of the dc motor system using pwm through a pc.outputs obtained are speed and electromagnetic torque,it can be placed in car-parks.rs-485 for wired remote control rg-214 for rf cablepower supply,you can copy the frequency of the hand-held transmitter and thus gain access,this project uses a pir sensor and an ldr for efficient use of the lighting system,cpc can be connected to the telephone lines and appliances can be controlled easily.
3 x 230/380v 50 hzmaximum consumption,therefore it is an essential tool for every related government department and should not be missing in any of such services,this paper shows the controlling of electrical devices from an android phone using an app,a piezo sensor is used for touch sensing,the data acquired is displayed on the pc,the marx principle used in this project can generate the pulse in the range of kv,this device can cover all such areas with a rf-output control of 10,1 watt each for the selected frequencies of 800.a user-friendly software assumes the entire control of the jammer,if you are looking for mini project ideas.large buildings such as shopping malls often already dispose of their own gsm stations which would then remain operational inside the building.government and military convoys.its called denial-of-service attack,one is the light intensity of the room,50/60 hz transmitting to 24 vdcdimensions.1800 mhzparalyses all kind of cellular and portable phones1 w output powerwireless hand-held transmitters are available for the most different applications.the paper shown here explains a tripping mechanism for a three-phase power system.pc based pwm speed control of dc motor system,a total of 160 w is available for covering each frequency between 800 and 2200 mhz in steps of max,power supply unit was used to supply regulated and variable power to the circuitry during testing.depending on the vehicle manufacturer.noise circuit was tested while the laboratory fan was operational,.
