T-Sense BLE 5.1 Temperature & Door Sensor
Wireless Temperature Monitoring & Door Status Sensor for Cold Chain, Logistics & Asset Security
The Topfly T-Sense BLE 5.1 Temperature and Door Sensor is a compact, industrial-grade wireless sensor designed for real-time temperature monitoring and door open/close detection across logistics, cold chain, fleet, and asset tracking applications.
Using Bluetooth Low Energy (BLE 5.1), the T-Sense sensor seamlessly integrates with compatible IoT gateways and asset trackers (such as Topfly GNSS trackers or IQFLOW-enabled devices), enabling low-power, long-range data transmission without the need for cellular connectivity on the sensor itself.
With its high-accuracy temperature sensing, IP67 waterproof enclosure, and long battery life, the T-Sense is ideal for cold chain transport, refrigerated storage, and cargo security monitoring.
Key Features
Temperature Monitoring with High Accuracy
The T-Sense sensor provides precise temperature measurements with:
- Accuracy: ±0.2°C (0°C to 60°C)
- Minimal long-term drift
- Optional external probe support (up to 15m cable)
This makes it ideal for cold chain logistics, food transport, and pharmaceutical monitoring.
Door Open / Close Detection
Integrated magnetic door sensor enables real-time monitoring of:
- Door open/close status
- Cargo access events
- Security breaches
The sensor uses a debounce filter (200ms) to ensure reliable detection without false triggers from vibration or movement.
BLE 5.1 Long-Range Connectivity
Utilising Bluetooth 5.1, the T-Sense supports:
- Up to 200m transmission range (open field)
- Low power consumption
- Seamless integration with BLE-enabled asset trackers
Ideal for container, trailer, and warehouse monitoring without additional wiring.
Long Battery Life (Up to ~5 Years)
Powered by a CR2477 1000mAh battery, the sensor delivers extended operation:
- Up to ~1800 days (≈5 years), depending on configuration
- Adjustable broadcast intervals for power optimisation
This ensures low maintenance and reduced operational costs.
Rugged Industrial Design (IP67)
Designed for harsh environments, the T-Sense features:
- IP67 waterproof enclosure
- Compact and lightweight design (23g)
- Wide operating temperature range (-30°C to +80°C)
Suitable for outdoor deployment and industrial environments.
Flexible Installation Options
Easy to install on various surfaces using:
- Screws
- Adhesive (polyurethane glue)
- Zip ties
Ideal for containers, trailers, cold rooms, and equipment enclosures.
Smart IoT Integration
The T-Sense is compatible with:
- Topfly BLE-enabled GNSS trackers
- IoT platforms such as IQFLOW, ThingsBoard, and MQTT-based systems
- BLE mobile apps for configuration and diagnostics
It supports Eddystone and Beacon protocols for flexible IoT deployment.
Typical Applications
The T-Sense BLE sensor is ideal for:
- Cold chain temperature monitoring
- Refrigerated transport and storage
- Container and trailer door monitoring
- Food and pharmaceutical logistics
- Warehouse and facility monitoring
- Asset security and tamper detection
