Overview
QR-based shipment monitoring
Scan data into Logmore Cloud with a phone
- Dynamic QR code uploads data without dedicated reader hardware
- Temperature thresholds and alarm profiles are managed in Logmore Cloud
Powerful data collection with Logmore QR data loggers
Logmore QR data loggers collect temperature and shipment condition data in transit, then upload it to Logmore Cloud through a simple phone scan.
QR Data Logger comes in many variants.
Choose the sensor mix for your shipments, attach the logger to the shipment, and let each scan upload evidence and reports for quality and logistics teams. All variants are powered by tiny coin cell batteries, so no DGR labeling is needed when shipping.

One strong flow: measure, scan, analyze.
The logger travels with the shipment, the receiver scans the QR code, and Logmore Cloud turns the measurements into reports and decisions.
01
Measure
Sender attaches the QR data logger to the shipment and starts recording the product conditions that matter during storage or transport.
02
Scan
When the receiver scans the QR code with a smartphone, the trip record opens instantly with no app or account needed.
03
Analyze
The owner can read the data, assess shipment status, and use Logmore Cloud for reporting, follow-up, and broader supply chain visibility.

Answers to the questions buyers ask most often.
Instead of listing raw specifications only, this section tackles the practical questions teams usually ask when they evaluate QR data loggers for real shipment workflows.
What does the logger measure?
Depending on the model, Logmore data loggers can measure temperature, humidity, shocks, ambient light, scan location, and external probe temperature for dry ice or deep-cold shipments. The model range starts with single-use temperature monitoring and extends to multi-condition shipment monitoring.
How do I start and stop recording?
Recording is managed through the Logmore workflow for the shipment. Teams configure the mission, attach the logger, and start monitoring before dispatch; the mission can then be ended in Logmore Cloud, through an API workflow, or according to the receiving process used by the customer.
How do I read the data?
Scan the Dynamic QR code with a smartphone. The scan uploads the logger record to Logmore Cloud, where teams can review graphs, shipment status, alerts, reports, certificates, and exportable evidence without USB readers or dedicated field hardware.
How accurate is it?
Accuracy depends on the logger model, sensor, and calibration setup. Logger 1 uses a 3-point calibrated internal temperature sensor with typical accuracy of ±0.3°C and maximum error of ±0.4°C. Calibration certificates are available from Logmore Cloud when documentation is needed.
How long does the battery last?
Battery life varies by model, sensor configuration, and measuring interval. Logger 1 typically runs for 4 months with a 1-year shelf life, standard reusable models can run up to 4 years, and external-probe deep-cold models can run up to 2 years.
Is it reusable or single-use?
Both options are available. Logger 1 is a single-use QR data logger for routes where recovery is impractical, while the broader Logmore logger range supports reusable workflows for recurring lanes where the device can be returned and used again.
