Cold chain temperature tracking with BLE sensors
Context
Cold chain logistics requires continuous temperature monitoring to prevent spoilage, protect sensitive goods and ensure compliance.
BLE sensors allow temperature monitoring without wired installations, and telematics provides traceability throughout the route.
Problem: temperature deviations without proof
Fleet operators often lack a reliable temperature record per trip, and spikes happen without detection or proof.
Manual checks are inconsistent, disputes are hard to resolve, and associating conditions with specific cargo zones remains difficult.
Solution: BLE sensor temperature tracking integrated into telematics
Carchain enables cold chain traceability by capturing sensor data and tying it to every trip.
BLE sensors can be added quickly without wiring and continue reporting during trips.
- Temperature and humidity readings from BLE sensors in the cargo area.
- Vehicle location and trip history for full route context.
- Time-stamped logs during transport for compliance and claims.
BLE sensor data flow
BLE sensor data flows from the cargo area to the telematics device and into Carchain, where alerts and reports are generated.
How it works (step-by-step)
- Install BLE temperature and humidity sensors inside refrigerated compartments or cargo zones.
- The telematics device reads nearby BLE sensors and filters out unrelated sensors.
- Temperature and humidity are captured in real time with timestamps and vehicle context.
- Set warning and critical thresholds to trigger alerts for deviations.
- Export temperature logs per trip or shipment as compliance-ready proof.
Benefits for fleet operators
Carchain keeps cold chain operations compliant, auditable and resilient.
Prevent spoilage and claims
Detect deviations early and reduce product loss and chargebacks.
Compliance-ready traceability
Get a full record of conditions throughout the journey for audits and proof.
Reduce disputes with customers
Time-stamped temperature logs linked to the exact route.
Zero-wiring installation
BLE sensors deploy fast and scale across vehicles and cargo units.
Cargo-zone grouping
Group sensors by proximity and avoid unrelated sensor noise.
Result: higher cargo safety, stronger compliance and faster issue resolution for cold chain fleets.
