Based on technical specifications for the **MH34TAG-R**, this component is a specialized **Active RFID Tag** (Radio Frequency Identification) primarily used in Real-Time Location Systems (RTLS) and personnel tracking. --- ## 1. Core Functional Components The MH34TAG-R is an integrated electronic assembly designed for low-power, long-range wireless communication. Its electronic architecture generally includes: | Component Type | Description | Purpose | | :--- | :--- | :--- | | **Microcontroller (MCU)** | Low-power 8-bit or 32-bit processor. | Manages logic, power states, and data encryption. | | **RF Transceiver** | Usually operates in the **2.4 GHz** (ISM Band). | Handles the transmission of the tag's unique ID to readers. | | **Internal Antenna** | PCB-etched or ceramic chip antenna. | Radiates the signal across the specified range. | | **Motion Sensor** | Integrated Accelerometer. | Detects movement to wake the device from "sleep" mode, saving battery. | | **Power Source** | Replaceable or fixed Coin Cell (e.g., CR2032). | Provides 3V DC power for active signal broadcasting. | --- ## 2. Key Technical Specifications The electronics are optimized for **longevity** and **security**. * **Frequency:** 2.4 GHz - 2.4835 GHz. * **Modulation:** GFSK (Gaussian Frequency Shift Keying). * **Read Range:** Typically up to 50–100 meters depending on the environment and reader sensitivity. * **Power Consumption:** * *Sleep Mode:* < 2µA (Micro-Amps). * *Transmit Mode:* ~10-15mA. * **Transmission Interval:** Configurable (e.g., every 1 second or based on movement). --- ## 3. Advanced Features ### Panic/Emergency Button The "R" in the model often signifies a specific revision or feature like a physical **Push Button**. When pressed, the electronic circuit triggers an immediate high-priority signal (SOS) sent to the central monitoring system. ### LED Indicator A small SMD (Surface Mount Device) LED provides visual feedback for: 1. Battery low status. 2. Successful transmission/pairing. 3. Panic button activation. --- ## 4. Usage Environment The internal PCB is typically housed in a **waterproof (IP67)** or water-resistant casing to protect the sensitive electronic components from sweat, rain, or humidity, as these tags are often worn as wristbands or lanyards.
