The **MH24TAG-R** is a specific electronic component primarily associated with **RF (Radio Frequency) communication** and **Asset Tracking** solutions, often used in conjunction with the *Wavetrend* active RFID ecosystem. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Overview The MH24TAG-R is an **Active RFID Tag**. Unlike passive tags (like those in credit cards), this device contains its own power source and transmitter, allowing it to broadcast its signal over much longer distances. ### 2. Technical Specifications | Feature | Specification | | :--- | :--- | | **Operating Frequency** | 2.4 GHz (ISM Band) | | **Battery Type** | Internal Lithium (Non-replaceable) | | **Battery Life** | Typically 3–5 years (depending on ping rate) | | **Read Range** | Up to 100 meters (line of sight) | | **Enclosure Rating** | Often IP67 (Dust tight and water resistant) | | **Mounting** | Industrial adhesive or mechanical fasteners | ### 3. Key Electronic Components The internal circuitry of the MH24TAG-R consists of several critical subsystems: #### A. Microcontroller (MCU) The "brain" of the tag. It manages the timing of the signal broadcasts (pings) and handles power management to ensure the battery lasts for several years. #### B. RF Transmitter Operating in the **2.4 GHz spectrum**, the transmitter uses GFSK (Gaussian Frequency Shift Keying) or similar modulation to send a unique ID to a compatible reader. #### C. Internal Antenna Because it operates at 2.4 GHz, the wavelength is short enough for a small, high-efficiency PCB antenna to be integrated directly onto the circuit board. #### D. Power Management Circuit Since the battery is integrated, the device uses ultra-low-power sleep modes. It only "wakes up" for a few milliseconds to transmit its data before returning to a deep sleep state to conserve energy. --- ### 4. Functional Features * **Anti-Tamper Mechanism:** Some variants include a light sensor or a micro-switch on the back. If the tag is removed from the asset, it sends a specific "tamper" alarm code. * **Motion Sensing:** Some models include an accelerometer. The tag remains silent while stationary and only broadcasts when it detects movement, further extending battery life. * **Unique ID:** Every tag is pre-programmed with a unique 32-bit or 64-bit ID code that cannot be altered. --- ### 5. Typical Applications 1. **IT Asset Management:** Tracking laptops and servers in data centers. 2. **Personnel Safety:** Tracking staff in hazardous environments. 3. **Inventory Control:** Locating high-value equipment in warehouses.
