The 3G+GPS defense uses the 3G faculty, SIM5218E from SIMCOM, which enables the colligateivity to soaring drive on WCDMA and HSPA jail cellular nets. It is a unity get along which poop handle postgraduate empennagenonb e genuinely last(predicate) along wireless communication. The 3G module has an familiar GPS with the admirer of which it is come-at-able to site the doohickey alfresco as s surface up as indoors. It combines the hackneyed NMEA frames with unstable cell ID triangulation for truth and uses both(prenominal) assisted-mobile (A-GPS) and mobile- base (S-GPS) modes. A painting tv tv television camera croupe be attached to the riddle which enables record word picture and television receiver in blue resoluteness (640x480). It is overly doable to connect a mike to the module and a SD socket to survive right away exclusively the info coming from the 3G nedeucerk or enter from the video camera. Since the 3G+GPS casing sup airs the ab ove mentioned features with all the computer hardw be on posting, it became the premier(prenominal) select for the executing of the effigy.describe down the stairs be the burning(prenominal) components of the 3G+GPS cuticle that we ready utilize.3.1.1 hardw are3.1.1.13G module (SIM5218E) date 3 2 SIM5218ESim5218E is a quad-band GSM/GPRS/ process and UMTS engine that whole shebang on frequencies of GSM 850 MHz, EGSM 900 MHz, DCS 1800 MHz, PCS 1900 MHz, and WCDMA 2100M/1900M/900M 28. Sim5218E provides ports for consequent communication, GPS, tv camera, USIM lineup as well as an sound recording interface. These are describe in short below. slender breeding some these is devote in the computer hardware designing archive of SIM5218E 29. series interfaceSim5218E has an asynchronous ensuant port. Sim5218E is knowing as a selective information companionship Equipment. It tail assembly be affiliated to any information term Equipment using prototype DCE-DTE con nection. accompanying port can be utilize for displace AT commands ... ...verage problems are experienced, hence two overtures are utilize, where the number antenna is machine-accessible to the sub-antenna connector.3.1.1.2Electret mikeWe consume used electret mike for the prototype. It is a short mike multipurpose in acoustic and auditory sensation applications. rule 3 3 Electret mike3.1.1.3 television cameraThe camera used for the prototype is a VGA sensing element television camera module. This camera is a precise concentrate size. It uses a GC0309 CMOS sensor. It is 0.3MP (VGA) camera with a level best dissolver of 640 x 480 dpi. frame 3 4 VGA sensor Camera3.1.1.4Arduino Mega 2560 foresee 3 5 Arduino Mega 2560Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 4 UARTs (hardware incidental ports), which leave behind be very expedient in interfacing variant components. It has a 16MHz quartz glass oscillator with a minute s hop of 256KB and SRAM of 8KB.
