Uberlogger: Bridging the Gap Between Performance and Affordability
Figure 1: The Uberlogger.
At Tameson, we are passionate about engineering and innovation. So when our longtime friend Paulus Potter, founder of Tecnion Technologies and an electrical engineer who we know from our time together at Eindhoven University of Technology (TU/e), told us he had developed a powerful yet affordable new data logger called the Uberlogger, we were eager to learn all about it. Paulus worked together with Bas Vermulst, assistant professor at TU/e and co-owner of SDR Engineering B.V., to design the hardware and software for the Uberlogger. After diving into the details and capabilities, we believe this product will provide great value to many of our customers.

What is the Uberlogger?
Paulus and founders Paul and Jan-Willem of Tameson have known each other since university and have remained friends ever since. Jan-Willem: "The Uberlogger is exactly the type of product we love to offer our customers. Innovative, versatile, affordable, and developed by a team committed to making a positive impact."
The Uberlogger is a fully standalone data acquisition system that can simultaneously log analog signals up to +/- 60V, data from NTC sensors, and digital inputs. It records the data directly to an SD card in convenient CSV format. With 16-bit resolution and a configurable sample rate from 1-250 Hz, it is a versatile tool suitable for many applications.
Key features and benefits
- Wi-Fi enabled for remote control via web interface, REST API, or simple physical start/stop button
- Logs data to SD card, 32 GB card included
- Wide +/- 60V analog input range ideal for many sensors and transducers
- 8 ports for NTC sensors (included), compatible with standard NTC 10K sensors and user-supplied 2.5mm JST connectors
- USB powered - can use wall adapter, PC, or battery pack
- Firmware updates enable adding new features over time
- 50% of profits of Tecnion Technologies are donated to support education for underprivileged children in Guatemala
How it works
All you need is a USB power supply, which can be a USB 5V power supply, PC or battery pack and you're good to go. A USB-C cable is included in the package.
Figure 2: Uberlogger front and side view.
The Uberlogger is useful for logging data from a wide range of sensors, switches, and transducers commonly used in industrial applications. The high 60V input range can directly interface with devices like pressure transducers and CO2 sensors without extra signal conditioning. Simultaneously measuring from multiple sensors makes it a great tool for applications like calibrating multi-zone underfloor heating systems.
While the Uberlogger packs in a lot of functionality, it may not be the best fit for every application. The analog inputs are not isolated, so care must be taken when connecting to high voltage systems. Overall though, the Uberlogger stands out as a highly capable yet cost-effective data logging solution, made even more compelling by the mission to support a very worthy cause. We look forward to seeing how our customers can put it to use, and to future enhancements as the product continues to evolve. To learn more, visit uberlogger.com or contact our customer support team.

Example applications
Sensors, switches & transducers
The large voltage range of +/- 60V makes the Uberlogger ideal for different switches and transducers. For example, pressure switch and transducers may have output voltages ranging from 0 up to 42 VAC/DC and can be connected to the Uberlogger without any problem. Measuring pressures with the Uberlogger at low or high frequencies becomes very affordable this way.
Different air quality sensors like CO2 can also be connected to the Uberlogger. Many of the Belimo Duct Co2 sensors have an output of 0V to 5V or 0V to 10V. Using the Uberlogger web interface or REST API you can retrieve this voltage and monitor these sensors remotely.
Underfloor heating calibration
When setting up the underfloor heating the valves of each zone of the underfloor heating must be calibrated to have an optimal heating of your house. If this is not done properly, your heating system may warm one zone too fast and another too slow. Calibration is generally done using a thermal IR camera, where you can scan the incoming water flow temperature and compare it to the returning water temperature. The IR camera, however, may not show the exact temperatures of each line simultaneously. Next to that, the calibration may take several days, so you cannot track the temperatures of the hoses over time.
With the Uberlogger you can measure up to 8 temperatures using the included NTC sensors. This way, you can measure the incoming and returning water flow temperature accurately and continuously by attaching the NTC sensor to the water hoses at central heating splitter.
Figure 4: Application example.
Since the Uberlogger can log the data for several days, you can leave the logger on site and keep excellent track of the temperature gradient over time and adjust the valve for each zone accordingly much more accurately, which is much more comfortable for the house owner.
What can the Uberlogger do for you?
These are just a few examples of what you can do with the Uberlogger. There are more features that will come to the Uberlogger which you can check out on the website www.uberlogger.com.

The story goes back to 2017
The story of starting Uberlogger goes back to 2017. Back then, Paulus Potter, a Dutch electrical engineering living in Eindhoven wanted to explore more of the world after some years of working as an engineer and wanted to know how people in non-western countries live and work.
“I visited Peru in 2016 and saw how different people were living there. I wanted to know and learn more about this”. He decided to go to Guatemala and after 3 weeks discovered Quetzaltrekkers. This is a non-profit hiking organization that gives all its proceedings to a school, called EDELAC (Escuala de la Calle), providing education for the poorest children in the city of Xela. Paulus decided to volunteer there and stayed for 1 year in total.

It was during that period that he considered himself to be very fortunate having everything he needed in life and having the ability to do pretty much everything he would like to do. “When you see that some of the children in Guatemala don’t have parents anymore, have proper clothes or sometimes even food, you realize what it means to be grateful for everything you have”. The poor indigenous people are not always well supported in Guatemala by the government or because of racism. For these reasons, he decided he wanted to help these children.

The first idea was to start Hikes.me, a website to sell hikes in Latin America. This went well slowly, but unfortunately COVID stopped the whole business entirely. After working a few years again as an engineer in the Netherlands, the customer came with the request to build a simple yet powerful logging device.
Together with Bas Vermulst, assistant professor at University of Technology Eindhoven and co-owner of SDR Engineering B.V., they designed the hardware and software and created the Uberlogger with the goal of giving 50% of the profit to EDELAC.
