GSM/GPRS module ( SIM900) original

Overview

The SIM900 is a reliable quad-band GSM/GPRS module that enables voice, SMS, and data communication over cellular networks. Its compact design and low power consumption make it an ideal choice for remote monitoring, IoT applications, and embedded projects in Egypt. Whether you're building a smart agriculture system, a vehicle tracker, or a home automation controller, the SIM900 provides a robust and cost-effective connectivity solution.

Key Features

• Quad-Band Support: Operates on GSM 850/900/1800/1900 MHz, ensuring compatibility with networks worldwide.
• Versatile Communication: Supports voice calls, SMS, and GPRS data transfer.
• Low Power Consumption: Sleep mode draws only 1.5mA, perfect for battery-powered applications.
• Compact Form Factor: Small footprint (24x24x3mm) fits easily into space-constrained designs.
• Wide Operating Temperature: Functions reliably from -40°C to +85°C.
• Simple UART Interface: Easy to interface with microcontrollers like Arduino, PIC, and STM32.

Applications & Use Cases

• IoT Prototyping: Connect sensors to the cloud via GPRS for real-time data logging.
• Remote Monitoring: Monitor equipment, environmental conditions, or security systems from anywhere.
• Vehicle Tracking: Build a GPS+GSM tracker for fleet management or personal vehicle security.
• Smart Agriculture: Automate irrigation and monitor soil conditions using SMS alerts.
• Home Automation: Control appliances via SMS or remote commands.

What's Included

• 1x SIM900 Module (breakout board with antenna connector)
• Note: SIM card and antenna are not included.

Compatibility

• Works with any microcontroller with a UART interface (e.g., Arduino Uno, Mega, ESP8266, STM32, Raspberry Pi via level shifter).
• Requires a standard SIM card with GPRS or SMS service from any Egyptian network provider (Vodafone, Orange, Etisalat, WE).
• Power supply must provide sufficient current (peaks up to 2A during transmission).

MOKWN Recommendation

For a quick start, pair the SIM900 with an Arduino Uno and our SIM900 breakout board (with voltage regulator). We also recommend using a 5V/2A power adapter and a high-quality antenna for optimal signal strength. This module is a dependable choice for makers and professionals alike, backed by our local support in Egypt.
