Logmore Guardians (QR Data Loggers)
What is a (data) logger?
A logger is a device that monitors set parameters in its environment and saves the data digitally. Logmore QR data loggers are a specialized type of a logger.
How can the data logger be so small?
Considerable effort has been put into building a data logger that can be equipped with small yet functional sensors and battery. We like to call it Logmore innovation.
Can I attach a data logger? How?
The data logger comes with an adhesive sticker that allows for easy attachment. For more extreme needs, the adhesive can be attached to a separate holder that can be screwed into a container.
How often does a data logger save data?
Every 15 minutes by default. The frequency can be configured to suit your needs between 10s and 30 days. Please note that the more often the tag saves data, the faster it will run out of battery.
For configurations, see
Can I just place a data logger within a parcel?
Sure. However, we recommend attaching the data logger to a surface where it is easy to scan. The logger comes with an adhesive that makes attaching it easy.
Why does the data logger's screen change?
The data logger's screen change every time it saves a measurement.
Where can I see a data logger's ID number?
The data logger's ID number can be seen on the data logger's screen next to the name Logmore, in the format of #XXXXXXXX. (Example: #00001234)
Why do the QR data loggers have their own IDs?
Every logger has its own ID number in order to distinguish it from all the other tags. This can be used to recognize different deliveries or packages.
What are the extreme temperatures in which the data logger stays fully functional?
The logger is functional in -30...60°C. The screen stops refreshing at 2°C in order to save battery while in freezing temperatures, but resumes refreshing when the logger is returned to warmer circumstances. The data logger still saves measurements while in the Below Zero mode. The data logger may cease operating at all if subjected to temperatures above 60°C, and goes into dormancy in temperatures below -30°C.
The measurement range is -30...60°C by default, but can be configured to a smaller range.
What are the extreme humidity levels in which the logger stays fully functional?
The QR data loggers are IP67 protected and operate in 5...95% RH (Relative Humidity).
Can I break the logger somehow by accident?
Yes. The loggers are durable and should endure normal use, but strong impacts and sharp objects may cause damage to the logger.
What if I lose or break a logger?
The first step is replacing the logger with another, if you have spares. The annual calibrations should ensure you have enough loggers to suit your subscription. If you don't have spares, purchasing more is advisable.
Why is there a hole in the logger?
The tiny hole in the corner of model 3 QR data loggers is for the humidity sensor. The earliest demo and pilot versions may also have a tiny hole for light sensors next to the button, but newer designs have made the need for that unnecessary.
