RFID Reader Modules

Instrumenting RFID technology has increasingly been accepted into various industries, from manufacturing to healthcare. Readers capable of connecting to the internet of things (IoT) are often considered the holy grail in RFID. The RI-STU-MRD2 module, a reader module developed by IDTECH, is a great example of the potential of a reader module in an IoT setup.

Application Field and Working Principle of RI-STU-MRD2

The RI-STU-MRD2 reader module is a compact and cost-effective solution for applications such as access control, asset tracking and inventory management. This module provides maximum read distance, superior performance, and intelligent signal processing. The RI-STU-MRD2 can be used in any environment, including in challenging RF conditions, such as metal, heavy traffic, or a mixture of both.

The working principle of the RI-STU-MRD2 reader module is rather straightforward. It is based on a transceiver configuration, wherein two antennas, one for transmit and one for receive, are connected to the reader module. Then, the RFID tags within range are transmited a signal from the transmit antenna, and the signal is received by the receive antenna. The reader module can then interpret the signal and gain the information encoded within.

The RI-STU-MRD2 reader module employs an ARM 32-bit Cortex-M3 processor and a 125 khz RF transceiver. It is also equipped with a real-time clock, an external IP port, a serial RS232/RS485 port, and a USB 2.0 port. Furthermore, the module is equipped with an integrated antenna and a special purpose power management IC.

Advantages of RI-STU-MRD2 Reader Module

The RI-STU-MRD2 reader module has several advantages, including:

• Compact size.
• Flexible power operation.
• High reliability and stability.
• Wide read range.
• Supports multi-protocols.
• Built-in memory.
• Sleek, lightweight design.
• Low power consumption.
• Easy integration with other systems.

The RI-STU-MRD2 module is an ideal solution for various applications, such as access control, asset tracking and inventory management. It has a read range of up to 8 meters which makes it suitable for all kinds of environments. The reader module is also equipped with a wide range of interfaces, which allows it to be easily integrated with other systems. Overall, the RI-STU-MRD2 provides a great solution for integrating RFID technology into an IoT system.
