<h1>Hard Tag: The Ultimate Solution for Advanced Asset Tracking</h1> <p>In my years of managing complex logistics operations, I've seen countless tracking solutions come and go. My personal experience has taught me that reliability in harsh environments is non-negotiable. This is where my technical aptitude for evaluating hardware specifications became crucial. I firmly believe that a tracking device's true value is proven not on a spec sheet, but in the field under extreme duress. For a fun application, we once used a batch of these tags in a corporate "Amazing Race" to track teams across a city—the data accuracy was phenomenal, and it was a huge hit.</p> <p>At TIANJUN, we have developed the HT-3000 Series Hard Tag to meet these rigorous demands. This product is engineered for durability and precision in the most challenging conditions.</p> <h2>Technical Specifications and Detailed Parameters of the TIANJUN HT-3000 Hard Tag</h2> <p>The following parameters are for reference data; specifics need to be confirmed by contacting backend management.</p> <h3>Physical & Core Specifications</h3> <h4>Dimensions and Build</h4> <ul> <li><strong>Dimensions:</strong> 98mm x 62mm x 28mm (L x W x H)</li> <li><strong>Housing:</strong> Reinforced polycarbonate with silicone gasket, rated IP68 (submersible up to 2m for 24 hours) and IK10 impact resistance.</li> <li><strong>Operating Temperature:</strong> -40°C to +85°C.</li> </ul> <h4>Electronics and Connectivity</h4> <ul> <li><strong>Primary Positioning:</strong> Multi-constellation GNSS (GPS, GLONASS, Galileo, BeiDou).</li> <li><strong>Backup Positioning:</strong> Wi-Fi Sniffing and Cell-ID (LTE Cat-M1).</li> <li><strong>Primary Communication:</strong> LTE Cat-M1 with 2G fallback (NB-IoT variant available).</li> <li><strong>Core Processing Chipset:</strong> Custom system-on-chip (SoC) integrating the Quectel BG95-M3 modem and a Nordic Semiconductor nRF52840 microcontroller for sensor processing. <em>Chip Code: TJ-HTCORE-V2.1</em>.</li> <li><strong>Internal Sensors:</strong> 3-axis accelerometer (for impact/shock detection), temperature sensor, and a tamper switch.</li> </ul> <h3>Performance and Power</h3> <ul> <li><strong>Battery:</strong> 10,000mAh industrial-g
