SIM900 arduino GSM Development board GSM GPRS Arduino Shield

The SIM900 arduino GSM Development board is a GSM/GPRS shield built around the SIMCom SIM900 module. It plugs onto an Arduino Uno-style board and lets your project send and receive SMS messages, make and answer voice calls and connect to the internet over GPRS, all controlled with simple AT commands over a serial link. It suits remote alarms, SMS-controlled relays and data loggers in places with no Wi-Fi.

SIM900 arduino GSM Development board Applications

• SMS alerts from alarms, sensors and water-level monitors
• Remote control of relays and pumps by SMS or phone call
• GPRS data logging to a web server
• Vehicle and asset trackers when combined with a GPS module
• Learning mobile communication and AT commands

What's in the Box

• 1 × SIM900 GSM/GPRS shield (SIM card not included)

Tip: The SIM900 is a 2G module, so check that your mobile operator still runs a 2G GSM network in your area before you build on it. Power the shield from an external supply that can deliver about 2 A; USB power alone often makes the module reset when it transmits.

Orders placed before 14:00 are ready for pickup the same day. Delivery across Lebanon usually takes 1–3 working days.
