WWW.ABC.COM/TEST.ASPX?C=<PULSECOUNT_32BIT>,<GPRS IMEI NO>, <DATETIME>,<BATTERY LEVEL>

BATTERY POWERED,
MICRO SLEEP MOST OF THE TIME, WAKE ON INCOMMING PULSE, INCREMENT COUNTER THEN GO TO SLEEP.
REAL TIME CLOCK MUST WAKE UP MICRO EVERY OUR TO TRANSMIT THE ABOVE HTTP GET QUERYSTRING.
PLEASE ALSO INTEGRATE RS232 TO PROGRAM DEVICE LATER, MUST BE ABLE TO CONFIGURE HTTP ADDRESS USING RS232, EG SEND: URL = WWW.ABC.COM/TEST.ASPX, MICRO WILL RESPOND "ok"

PLEASE USE SIM COM MODULE + EAGLE FOR PCB IS PREFERRED.
PLEASE USE PIC MICRO, DEVELOP SOFTWARE FOR MPLAB IDE.

YOU DESIGN THE SCHEMATIC/BOARDLAYOUT, CHOOSE MATERIALS TO KEEP MANUF COSTS TO MIN.
WE WILL BUILD THE PCB,
YOU DEVELOP FIRMARE WE TEST WITH BUILT PCB
