The DB01 Temperature & Humidity Sensor is a professional-grade IoT device developed by EELINK Communication Technology Co., Ltd. through years of continuous product optimization. Designed for logistics, cold chain operations, and asset monitoring, DB01 goes far beyond a traditional data logger. It functions as a complete Bluetooth beacon data system, combining precise sensing, intelligent alarms, local data storage, and seamless transmission.
By delivering stable, transparent environmental data, the DB01 Temperature & Humidity Sensor enables enterprises to reduce operational risk, control costs, and improve efficiency with confidence.
Core Highlights: A Solid Foundation for Trustworthy Monitoring
At its core, the DB01 Temperature & Humidity Sensor uses Bluetooth 5.0 technology, ensuring stable communication while maintaining ultra-low power consumption. As a result, the device operates reliably even in complex logistics environments that require continuous monitoring.
DB01 measures temperatures from –20°C to +60°C and humidity levels from 0%RH to 100%RH. This wide operating range allows the device to adapt easily to cold storage facilities, refrigerated transportation, and standard warehouse environments.
In addition, DB01 integrates a built-in light sensor and acceleration sensor, enabling multidimensional environmental awareness. These sensors actively detect abnormal events such as unauthorized box opening, vibration, or tilting. Consequently, DB01 delivers a deeper and more accurate understanding of real conditions during transportation and storage.
The DB01 Temperature & Humidity Sensor also supports multiple intelligent alarms, including temperature alerts, humidity alerts, light alerts, vibration alerts, tilt alerts, and low-battery alerts. Through real-time notifications, teams can identify risks early and respond before losses occur.
From a data management perspective, DB01 records date, time, temperature, humidity, battery status, and MAC address simultaneously. Equipped with 4MB of flash memory, the device stores up to 100,000 records, ensuring uninterrupted data continuity even when network connectivity is unavailable.
Users can retrieve historical data easily by connecting DB01 directly to a PC via USB. When paired with EELINK Bluetooth gateway devices such as TK419-3, TK419, TK418, and GPT46, DB01 uploads data smoothly to cloud platforms for centralized monitoring and analysis.
Application Scenarios: Real-World Protection Where It Matters Most
Cold Chain Pharmaceutical Transportation
In pharmaceutical cold chain logistics, even brief temperature deviations can compromise product safety. Logistics teams place the DB01 Temperature & Humidity Sensor inside insulated containers to monitor temperature and humidity continuously throughout the journey.
When refrigeration performance declines or containers open unexpectedly, DB01 triggers instant alerts. As a result, teams can take corrective action immediately and prevent irreversible damage. After delivery, the complete temperature history provides reliable documentation for regulatory compliance and quality assurance.
Fresh Food and Agricultural Supply Chains
Fresh food transportation demands strict environmental control. By deploying the DB01 Temperature & Humidity Sensor, companies gain full visibility into temperature fluctuations, humidity changes, and handling conditions during transit.
Furthermore, vibration and tilt data reveal improper loading practices or rough handling. Over time, these insights help logistics operators optimize routes, improve packaging design, and strengthen quality control across the entire supply chain.
Warehousing and High-Value Asset Storage
Warehouses storing precision equipment, electronics, or sensitive materials require stable environmental conditions. The DB01 Temperature & Humidity Sensor continuously monitors storage environments and actively issues alerts when conditions exceed predefined thresholds.
Facility managers can respond immediately to HVAC failures or sudden environmental changes. This proactive monitoring strategy reduces asset degradation and minimizes financial risk.
Long-Distance and Cross-Border Logistics
During maritime shipping or long-distance transportation, connectivity often becomes limited. Even in these conditions, the DB01 Temperature & Humidity Sensor continues recording data locally without interruption.
Once connectivity returns, the system uploads all stored data seamlessly. Therefore, DB01 ensures complete traceability, which proves especially valuable for international trade compliance, claims handling, and dispute resolution.
Value Summary: From Data Collection to Smart Decisions
The true strength of the DB01 Temperature & Humidity Sensor lies in its ability to transform raw environmental data into actionable intelligence. Through transparent monitoring, early warnings, and verifiable records, DB01 empowers businesses to operate more efficiently and responsibly.
As a result, organizations achieve stronger risk control, enhanced customer trust, and long-term operational optimization.
