با استفاده از شیلد sim900 و قرار دادن آن روی برد آردوینو می توان از تمامی امکانات GPRS استفاده نمود. همچنین قابلیت امکان ارسال و دریافت sms و برقراری تماس نیز امکان پذیر می باشد که البته با داشتن سوکت هدفون و میکروفون برقراری تماس ساده تر خواهد بود. برای تغذیه این برد آداپتور 9 ولت 2 آمپر پیشنهاد می شود.
Product Introduction
GPRS Shield- expansion board is a serial GSM / GPRS wireless module. The purpose is to allow fans to learn quickly Arduino GSM / GPRS mobile phone development, and can be applied to give the class wireless development projects, but also for the development of various remote control, such as wireless meter reading, intelligent home appliances, ultra-long-range control.
GPRS Shield is compatible with all standard Arduin development board. GPRS Shield is a 4-band GPRS / GSM module supports four kinds of standard band 850/900/1800 / 1900MHz, can send SMS text messages, phone calls, faxes and all other mobile phones with GPRS function. GPRS Shield allows you to very quickly understand wireless handset development processes and development.
GPRS Shield of three operating modes:
Short Message Service text messaging service mode
Audio Music mode
GPRS mode
Module uses a standard 2.54-pin interface row, onboard a super capacitor module can ensure the RTC clock in case of power outages 1-2 days time, can be used to study the development of mobile timing alarm clock function .
Features:
And Mega2560 fully compatible Arduino development board series
Serial communication, the freedom to choose the hardware serial ports (D0 / D1) or software serial port (D2 / D3) and the motherboard communication
SIM900 , all IC all stay out, not only UART port, DEBUG port, including all GPIO port and KEY, PANEL other interfaces
On-board super capacitor, to ensure RTC work
Precautions:
After the plug Arduino board, we sometimes need to simultaneously connect 9V DC power supply. The reason is that the current GPRS Shield boot and work up to the maximum peak current required 2A, but the USB port is unable to provide such a large current, it must be an external power supply equipment.
Ensure that your SIM card is not locked
GPRS Shield communication baud rate is preferably 19200 bps 8-N-1 (GPRS Shield default automatic matching baud rate)
