Description EM-18 RFID Reader Module – 125kHz Contactless Reader for Embedded Systems Upgrade your embedded or IoT project with the EM-18 RFID Reader Module, a powerful and compact solution for 125kHz RFID-based applications. Whether you’re developing attendance systems, access control solutions, or smart automation projects, the EM-18 offers reliable performance with a simple integration process. Product Overview The EM-18 module is a low-cost RFID reader that operates at a frequency of 125kHz. It can detect RFID tags within a range of up to 10 cm, making it ideal for applications where contactless identification is required. This module reads the unique ID of any RFID tag in proximity and transmits it using serial communication (UART or RS232) at a baud rate of 9600 bps. If you’re building a custom IoT gateway or working with microcontrollers like Arduino, Raspberry Pi, or ARM-based platforms, the EM-18 integrates seamlessly into your workflow with minimal wiring. Key Features of EM-18 RFID Reader Frequency: 125kHz (supports EM4100 cards) Communication Protocol: UART (TTL) and RS232 Baud Rate: 9600 bps (default) Operating Voltage: 5V DC Detection Range: Up to 8–10 cm Response Time: < 100ms Easy Plug & Play: Compatible with most development boards ⚙️ Applications The EM-18 module is widely used in: RFID Attendance Systems – Track employee or student presence effortlessly. Access Control Systems – Secure entry points using RFID tags. Library Management – Use RFID cards to manage book issues and returns. IoT Projects – Integrate with your Vihaan IoT Gateway for smart device recognition. Inventory Management – Tag and track assets across warehouses or retail. Time Logging Systems – Record working hours via contactless scanning. For a complete solution, check out our RFID Tags & Cards compatible with the EM-18 module. Connectivity & Integration The module outputs data through a simple 9600-baud serial connection. Connect it to your Arduino, ESP32, or FreeBSD-powered system using the TTL pins, and you’ll be scanning RFID tags in no time. It’s the perfect match for projects involving FreeBSD IoT deployments or custom ARM-based embedded hardware. Package Includes 1x EM-18 RFID Reader Module(Note: RFID tags or cards sold separately.)
