Frequently Asked Questions
Q: Does the USB temperature humidity data logger require special software to use?
A: No special software is required to export data. Simply plug the logger into a USB 2.0 port and it automatically generates a PDF report and CSV file. Optional PC data management software is available for configuring logging parameters, alarm limits, and start delays.
Q: Is the data logger reusable, or is it single-use only?
A: The ALLOYSEED data logger is fully reusable. Once you have downloaded and saved your data, you can reset the device and redeploy it for another monitoring cycle — making it an economical choice for ongoing warehouse or logistics operations.
Q: What is the maximum number of data points this humidity and temperature recorder can store?
A: The logger can store up to 32,000 data points. With the default 10-minute logging interval, that equates to over 200 days of continuous recording — more than sufficient for most long-haul shipments or extended storage monitoring.
Q: Is a battery included with the USB temperature humidity data logger?
A: No, the CR2032 3V battery is not included and must be purchased separately. The device is otherwise complete and ready to configure straight out of the box.
