Wireless Temperature Data Logger

Eupry’s wireless temperature data logger constantly send data to the web-based software via WiFi. It provides real-time temperature report of your refrigerator, freezer, storage area, etc. 

Once temperature deviation happens, it will immediately send you SMS / E-mail alarm, which minimizes the risks during monitoring process.

Learn about the process

How do wireless temperature data loggers work?

Wireless data loggers work by constantly measuring (temperature, humidity, CO2, Pressure etc.) and sending the data on a regular basis to a server via WiFi. The server is either situated locally or in the cloud.

The wireless data logger often stores measurements locally for longer or shorter periods, and then sends this data to the server.

The advantage of having a wireless data logger compared to the usb logger is that the wireless can transmit data automatically without the need of manual work. 

The wireless data logger can send data immediately if temperature excursions occur, which in turn can send an alarm to the users of the system. This means that the correct actions can be performed, thus minimizing the risk of actual non-conformities.

Data loggers are electronic devices used for monitoring and storing environmental parameters within predefined frequencies.

A Wireless Data Logger transmits the recorded data automatically to the web-based system through WiFi. It eliminates the need for manually having to export data via USB. This allows for effective documentation, analysis, and validation and even allows for the users of the system to receive alarms if any temperature excursions should occur.

A data logger can cost anywhere between $500 to $3000. However, there are often tremendous hidden costs related to purchasing a data logger as it will need yearly recalibrations which are not covered by the initial cost of acquisition.

Alternatively, you can get a subscription, where you do not have to have to waste time finding a third party that can recalibrate your sensors and data loggers as that is included in the subscription. A recently developed price calculator shows you how much you have to spend yearly. Try it here! 

Previously you had to connect your data logger to your computer before the data could be read. With a wireless data logger, this is a thing of the past. By using WiFi connection, it automatically transmits data to a website from where you can easily access the data.

Temperature data loggers operate much like thermometers, but instead of only measuring, the data is also stored on the device which can later be recovered by connecting it to a computer. For wireless temperature data loggers, the recovery of data happens automatically through WiFi connection.

A data logger can monitor various environmental parameters but is most frequently used for measuring temperature, humidity, carbon dioxide, and differential pressure. This makes them useful in many different applications such as temperature validation and mapping exercises.

Key aspects to consider when selecting a data logger:

  • Is it wireless?
  • Compatible sensor types
  • Size
  • Real-time operation
  • Are recalibrations included in the price?


  • Collection of data is fully automatic 
  • Risks are lower as it does not rely on personnel remembering to make readings
  • Readings are more accurate than if made by a person, as it is made by accredited sensors.
  • Wireless Data loggers and sensors can be placed in all heights or other dangerous places, as no one has to go there.
  • Readings can be seen in real-time, quickly, and safely from any computer or tablet
  • Wireless data logging allows for getting alarms immediately if temperatures rise above set criteria, for example, if someone has forgotten to close a door to a refrigerator.

Wireless Data loggers are used to record environmental parameters over time. Various use cases exist, but wireless data loggers are most frequently used to record temperature in refrigerated storage equipment used for medicine. Other popular choices include humidity, carbon dioxide, and differential pressure.

Wireless data logging has many different applications across industries, as it can measure essentially any environmental parameter. As an example, wireless data logging is often used to measure temperature in the pharmaceutical industry as this industry is known for having high compliance and documentation requirements.

A wireless data logger obsoletes the use of a USB-data logger and the process of manually having to export data. 

The best practice is to have all data loggers in your fleet calibrated on an annual basis and at the same time. Having them calibrated every twelve months ensures optimal accuracy and ideal compliance.

Additionally, it is possible to get a subscription for both wireless data loggers and yearly calibrations where the re-calibrated loggers are sent annually, thereby giving you complete peace of mind.
