SIM808 GPRS/GSM+GPS Shield

Features

• Quad-band 850/900/1800/1900MHz.
• GPRS multi-slot class12 connectivity: max. 85.6kbps(down-load/up-load).
• GPRS mobile station class B.
• Controlled by AT Command (3GPP TS 27.007, 27.005 and SIMCOM enhanced AT Commands).
• Supports Real Time Clock.
• Supply voltage range 5V ~ 12V.
• Supports for Bluetooth 4.0.
• Integrated GPS/CNSS and supports A-GPS.
• Supports 3.0V to 5.0V logic level.
• Low power consumption, 1mA in sleep mode.
• Supports GPS NMEA protocol.
• Standard Micro SIM Card.

Application Ideas

• M2M (Machine 2 Machine) Application – To transfer control data using SMS or GPRS between two machines located at two different factories.
• Remote control of appliances – Send SMS while you are at your office to turn on or off your washing machine at home.
• Remote Weather station or a Wireless Sensor Network – Make it with [Crowduino v1.0|Crowduino v1.0] and create a sensor node capable of transferring sensor data (like from a weather station – temperature, humidity, etc.) to a web server
• Vehicle Tracking System – Install GPRS+GSM+GPS Shield in your car and publish your location live on the internet. Can be used as an automotive burglar alarm.

Cautions

 

• Make sure your SIM card is unlocked.
• The product is provided as is without an insulating enclosure. Please observe ESD precautions especially in dry (low humidity) weather.
• The factory default setting for the GPRS Shield UART is autoloading. It supports baud rate from 1200 bps to 115200bps. (Can be changed using AT commands).
