Transporting sensitive goods always comes with risks. One of the most common threats is shock—sudden impacts, drops, or rough handling that may damage products even if the packaging looks intact. With Logmore loggers, you can easily monitor shocks throughout the supply chain to ensure your goods arrive safely.
From Logmore Data Loggers the Logger 30 and Logger 60 support shock monitoring. Default configurations can be found from the Data sheet.
How Shock Monitoring Works
Logmore data logger with a built-in accelerometer that records impacts exceeding a defined threshold (measured in g-force). When a shock event occurs, the logger saves the data point, including:
- The time of the event
- The intensity of the shock (in g)
- The direction of the impact (X, Y , Z axis)
This gives you a clear insights on what happened during transportation, allowing you to verify product integrity and identify potential problem points in your logistics chain.
In practice this means that the shocks are recorded when they happen regardless of the Logger's measurement interval with other sensors. The threshold to start measuring should be set so that the shocks recorded are meaningful and important information.

Setting Up and Optimizing Shock Monitoring
Choose your wake-up threshold
Define the g-force level at which the logger will record an event. For example, fragile electronics may require a lower threshold, while durable goods can be set higher. Also the weight and size of the goods monitored affects the optimal threshold. The bigger and heavier the object, the smaller the G-forces tend to be, and the more damage a seemingly small G-force impact can cause.
Example thresholds.
- Heavy industrial equipment (hundreds of KG in weight): 2G
- Pallet sized shipment: 4G
- Parcel sized shipment: 8G
Attached the logger properly
The shock monitoring from an object is realiant on the physical connection between the logger and the goods. If the logger isn't properly fixed to something, the shocks recorded won't correlate with the shock the goods are actually experiencing. For example if there's cardboard box in between, the box will damp the impacts or if the logger is loose in the box the logger's ability to move around will significantly suppress the G-force recorded.
After the logger is properly configured and fixed to it's place start the logger – Begin monitoring as the shipment leaves your facility. Once the shipment arrives, scan the QR code to upload the data to Logmore Cloud and review In Logmore Cloud. You’ll see a full report of any shock events, including timestamps and severity.
