Description:
SIM900 GSM/GPRS Module is a QUAD BAND GSM/GPRS module which compatible with Arduino. The module works to add both of GSM features (voice call or SMS) and GPRS features. The advantages of these modules are the VCC and TTL serial levels that have 5V voltage, so you can directly connect it to Arduino or another minimum system with 5V of the voltage level. There are so many GPRS/GSM modules on the market which need to add 5V regulator and level converter circuit, while SIM900 GSM/GPRS module already has a built-in regulator circuit and TTL level converter on the board.
Specification:
Quad-Band 850 / 900/ 1800 / 1900 MHz - would work on GSM networks in all countries across the world.
GPRS multi-slot class 10/8
GPRS mobile station class B
Compliant to GSM phase 2/2+
Class 4 (2 W @ 850 / 900 MHz)
Class 1 (1 W @ 1800 / 1900MHz)
Control via AT commands - Standard Commands: GSM 07.07 & 07.05 | Enhanced Commands: SIMCOM AT Commands.
Short Message Service - so that you can send small amounts of data over the network (ASCII or raw hexadecimal).
Application:
M2M (Machine 2 Machine) Applicatoions
Remote control of appliances
Remote Weather station or a Wireless Sensor Network
Vehicle Tracking System with a GPS module
Cautions:
Make sure your SIM card is unlocked.
The product is provided as is without an insulating enclosure. Please observe ESD precautions specially in dry (low humidity) weather.
The factory default setting for the GPRS Shield UART is 19200 bps 8-N-1. (Can be changed using AT commands).
