Precision at Every Degree
In cold chain operations, real-time temperature and humidity monitoring helps reduce spoilage, improve compliance, and cut avoidable energy waste.
Even a small deviation can compromise food quality, pharmaceutical integrity, or regulatory performance. That is why more operators now treat temperature and humidity visibility as a baseline requirement rather than an optional upgrade.
Our Sensor Lineup: Built for the Demands of Cold Chain Logistics
1. TSTH1-B – Standard Temperature & Humidity Monitoring
A compact BLE sensor ideal for in-box monitoring.
Range: -20°C to +60°C
Real-time humidity and temperature monitoring
Up to 5 years of battery life
IATA compliant for air freight
Plug-and-play with all BLE-capable trackers (SolarX, TLW2, etc.)
→ Best for: General refrigerated logistics (food, flowers, cosmetics, vaccines)
2. T-Sense – Temperature + Door Status Sensor
All the benefits of the TSTH1-B, plus cargo door open/close event detection
Magnetic door open/close detection
Long battery life (rechargeable)
BLE 5.0 connectivity
Combine temperature trends with door activity
Helps ensure chain of custody and tamper protection
→ Best for: High-value pharmaceuticals, cargo containers, and compliance-sensitive freight
3. T-One – Temperature Probe Sensor for Extreme Environments
Designed for deep cold or high-heat environments where standard sensors fail.
An external probe inserted into payload (-55℃ ~ +150℃ (-67°F ~ 300°F))
Tracks ultra-low (e.g. dry ice transport) or high-temperature cargo
Battery remains outside the cold zone, maintaining performance
Optional calibration for medical-grade accuracy
→ Best for: Cryogenic cargo, clinical trials, chemical logistics, high-temp cooked goods
Recommended Sensor Selection Guide
| Sensor | Key Strengths | Ideal Use Case |
|---|---|---|
| TSTH1-B | Compact, general-purpose monitoring | Food, flowers, vaccines, cosmetics |
| T-Sense | Door event + temperature fusion | Container security, customs inspection compliance |
| T-One | Extreme temp probe, isolated battery | Dry ice, pharma trials, lab samples, chemicals |
Sensor-First vs Tracker-First: Why the Difference Matters
Many cold chain solutions focus on GPS location first, and temperature second. That’s not enough.
For highly perishable cargo, Cold Chain Visibility, knowing “where” it is means nothing if you don’t know “how” it is.
Our sensor-first strategy ensures temperature & humidity metrics are always prioritized, even when the location signal may be intermittent (e.g., in aircraft cargo bays).
Seamless Integration
All sensors can be paired with Topflytech’s BLE-compatible trackers. Data streams directly into our IoT platform or your custom system via open API.
