Take your services to a higher level without having to invest in an IT department. Calculus provides you with the tools you need.

Remote insight

The Calculus platform offers tools for complete control in the most diverse areas. Like Smart Assets, asset tracking via a GPS Tracker for monitoring and securing vehicles and mobile or fixed equipment. Or Smart Buildings, for controlling and optimising, among other things, energy and water consumption, the indoor and outdoor climate and CO2 monitoring via Private LoRa.
Remotely following, monitoring and operating all these things results in profit, both in terms of time and money. Plus: the system leads to a more accurate deployment of (maintenance) staff. 


The Calculus platform has been developed for use in a wide variety of fields. The plug-and-play system is very easy to operate – wherever you are – and you can share insights with third parties in real time.

Knowledge is power.

Knowledge is power. Every improvement starts with the collection of data. Analysis of this data provides you with the necessary insights to start your improvement process.

Calculus collects data in various ways. We link up with various sensors via private LoRa, hardware developed in-house, and other data sources. These could be your own data files, publicly available data, and links to various platforms.

With the Calculus platform, we not only give you insights into all relevant data; we also help you put this knowledge to good use.
