GSM SIM800 SHIELD FOR ARDUINO











This module is built with SIMCOM Make SIM800 Quad-band GSM/GPRS engine, works on frequencies 850 MHz, 900 MHz, 1800 MHz and 1900 MHz. It is very compact in size and easy to use as plug in GSM Modem on to Arduino UNO or MEGA
The baud rate is configurable from 9600-115200 through AT command.Initially Modem is in Auto baud mode.
The modem needs only two wires (Tx, Rx) except Power supply to interface with microcontroller/Host.

Features:

Quad-Band GSM/GPRS 850/ 900/ 1800/ 1900 MHz.

5V interface for direct communication with MCU kit.

Configurable baud rate.

SMA connector with GSM L Type Antenna.

Built in SIM Card holder.

Built in Network Status LED.

Inbuilt Powerful TCP/IP protocol stack for internet data transfer over GPRS.

Input Voltage: 9V-12V DC.

Headphone jack for audio out.


For testing follow the given steps:

Provide external 12v supply to DC jack.Do not power up from Arduino.
Inset the simcard.
Then push switch to ON.
Power LED is ON , as well as buzzer is ON.
There is another two LEDs will on , One is for network selection(Yellow) and
Another for range selection(Green).Range LED blinks fast that means range is in Search mode.Slow blinking indicates Network available.
Make connection with PC through TTL .
Open hyperterminal and check through commands.
