SIM900 GPRS GSM Arduino Shield
GPRS Shield provides you GSM cell phone network to receive data from a remote. shield allows you to achieve this via three methods:
- Short Message Service
- GPRS Service
Item Min Typical Max Unit Voltage 4.8 5.0 5.2 VDC Current / 50 450 mA Dimension(with antenna) 110x58x19 mm Net Weight 76±2 g
- Based on SIMCom‘s SIM900 Module
- Quad-Bahttp://simcomm2m.com/En/nd 850 / 900/ 1800 / 1900 MHz – would work on GSM networks in all countries across the world.
- Control by 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).
- Embedded TCP/UDP stack – allows you to upload data to a web server.
- Speaker and Headphone jacks – so that you can send DTMF signals or play recording like an answering machine.
- SIM Card holder and GSM Antenna – present onboard.
- 12 GPIOs, 2 PWMs and an ADC (all 2.8 volt logic) – to augment your Arduino.
- Low power consumption – 1.5mA(sleep mode)
- Industrial Temperature Range -40°C to +85 °C
- Make sure your SIM card is unlocked.
- The product is provided without an insulating enclosure. Please observe ESD precautions specially in dry (low humidity) weather.
- The factory default setting of the GPRS Shield UART is 19200 bps 8-N-1. (It can be changed by AT commands).
- When using GPRS Shield with Seeduino Stalker, please remember to dismount the OK_READ Jumper (i.e. open it). This will disconnect the Battery Charger IC’s OK pin from the microcontrollers Digital Pin 7 and hence allow unhindered communication with GPRS Shield by using New Soft Serial Library.
