Starting a data logger is straightforward once you understand the basics. A data logger records temperature and environmental conditions over time, and activating one before a shipment typically involves a simple button press, NFC tap, or peel-and-stick step. This guide covers what data loggers do, how to start one correctly, and what to check before your shipment departs.
What is a data logger, and how does it work in cold chain monitoring?
A data logger is a small electronic device that continuously records temperature, and sometimes humidity or other environmental conditions, throughout a shipment. In cold chain monitoring, it serves as an objective record of what happened to a product between the moment it left the warehouse and the moment it arrived at its destination.
The working principle is simple. Once activated, an internal sensor measures the surrounding temperature at set intervals, such as every 10 or 30 minutes. Each reading is stored in the device’s memory. When the shipment arrives, the data is retrieved and reviewed to confirm whether conditions stayed within acceptable limits.
There are different types of data loggers used in cold chain logistics. Single-use electronic loggers use plastic housings and lithium batteries, with data retrieved via USB or Bluetooth. Reusable electronic loggers work similarly but are designed for multiple trips. Paper-based data loggers, as developed by Tapp, use NFC technology and a lithium-free design, with data accessible by tapping any NFC-enabled smartphone and syncing automatically to a cloud dashboard.
How do you start a data logger for a shipment?
Starting a data logger correctly is essential. An incorrectly activated logger may record no data or may log conditions before the product is even packed, making the record unreliable. Follow these steps before every shipment:
- Configure your settings in advance. Before activation, confirm the logging interval and alarm thresholds match your product’s requirements. Pharmaceuticals and fresh produce often need tighter intervals than ambient goods.
- Choose the right activation method. Depending on the logger type, activation is done via a button press, an NFC tap with a smartphone, or simply peeling a protective strip. Check the manufacturer’s instructions for your specific device.
- Activate as close to packing time as possible. Starting the logger too early means recording conditions in a warehouse rather than around the product itself.
- Place the logger correctly inside the packaging. Position it near the product, not against the packaging wall. Avoid placing it directly on ice packs or heat sources, as this skews readings.
- Verify the logger has started. Most devices provide visual confirmation, such as a blinking LED or a confirmation screen. For NFC-based loggers, a quick tap confirms activation status.
- Record the logger ID with the shipment documentation. This links the temperature record to the specific consignment, which is essential for traceability and compliance purposes.
Electronic data loggers require e-waste disposal at the end of their life, so it is worth speaking with a cold chain monitoring specialist when selecting a logger type for high-volume shipments.
How Tapp helps you start cold chain monitoring instantly
Tapp has developed paper-based NFC data loggers that remove nearly every barrier associated with traditional logger setup. There is no dedicated app to install, no USB hardware to carry, and no lithium battery to worry about during air freight.
- No app required: Any NFC-enabled smartphone can activate and read the logger instantly, with no software installation needed.
- Tap-to-activate: A single tap starts the logging process, reducing setup time and the risk of human error.
- Automatic cloud sync: Data uploads to the TappOS dashboard the moment the label is read, giving both sender and receiver access to the temperature record without manual file transfers.
- EN12830-certified accuracy: Tapp’s loggers meet the professional standard required for food, pharmaceutical, and agricultural cold chains.
- Lithium-free and eco-friendly: Unlike single-use plastic loggers, the paper-based design contains no lithium battery, making it safer for air transport and recyclable through standard paper waste streams globally, significantly reducing e-waste.
