GSM & GPS Two-In-One SIM808 Module w/ SMA Antenna

  • RM254.40

  • Ex Tax: RM240.00
  • Product Code: SIM808
  • Availability: In Stock
SIM808 module is a complete Quad-Band GSM/GPRS module which combines GPS technology for satellite navigation. The compact design which integrated GPRS and GPS in a SMT package will significantly save time for users to develop GPS enabled applications. Featuring an industry-standard interface and GPS function, it allows variable assets to be tracked at any location and anytime with signal coverage.The module can be controlled via AT commands.
 
 
Features
  • Quad-band 850/900/1800/1900MHz - Connect onto any global GSM network with any 2G SIM
  • Fully-integrated GPS (MT3336 chipset with -165 dBm tracking sensitivity) that can be controlled and query over the same serial port
  • Make and receive voice calls using a headset or an external 32Ω speaker + electret microphone
  • Send and receive SMS messages
  • Send and receive GPRS data (TCP/IP, HTTP, etc)
  • PWM/Buzzer vibrational motor control
  • AT command interface with "auto baud" detection

Connect to Arduino UNO  (wiki.eprolabs)

Hardware and Software Required

  • SIM 808 Module
  • Arduino UNO
  • Arduino IDE (1.0.6V)

 

Hardware connections

The SIM808 module has to be connected to Uno as follows:

  • Vcc to 3.3V
  • Gnd to Gnd
  • RXD to digital pin 10
  • TXD to digital pin 9

Note: When the board is power on, the LED (PWR) will light up.After a long press (about 2 second) on this button, the other three LEDs(D3,D4,D5) will be light. And one of them starts to flash,this suggests that SIM808 is beginning to work now. When the power supply, GSM and GPS antenna and SIM card are connected to the module correctly,the LED will be flash slowly (3Second delay), that indicates that the module is registered to the network, and the user can make a call or do something else. 

 

Program for SIM 808 Module

For programming the SIM 808 module,the user should upload the given code.Now open the serial monitor and simply type the AT commands according to the requirement.For example if you want to make a call,just type ATD+(country code)mobile number; and press ENTER key.Likewise the data can be transferred from our phone to SIM module and vice versa by using Bluetooth AT commands.

 

#include <SoftwareSerial.h>
SoftwareSerial mySerial(9, 10);

void setup()
{
   mySerial.begin(9600);   
   Serial.begin(9600);   
   delay(100);
}

void loop()
{
   if (Serial.available()>0)
    mySerial.write(Serial.read());
   if (mySerial.available()>0)
    Serial.write(mySerial.read());
}
