Smart Wireless: A Guide to the World of IQRF - Episode 13 - Sensorics with IQRF in the Kingdom of Tonga

 

How did Czech technology find its way to the Pacific Ocean?

In this episode, we explore a unique international collaboration between the Technical University of Ostrava (VŠB-TUO) and Christ University in Pacific, located in the Kingdom of Tonga.

Experts from Ostrava deployed an autonomous sensor system for monitoring weather conditions and building stability – operating wirelessly, energy-independently, and fully online thanks to IQRF technology.

What you will learn in this episode

Researchers from VŠB-TUO travelled all the way to Tonga to build a compact but technologically advanced IoT system on a local university campus. They installed meteorological sensors and structural-stability detectors on the roof and within the building, taking measurements every few minutes – temperature, humidity, air pressure, and any structural tilt.

All devices communicate through an IQRF mesh network, eliminating the need for cabling – a crucial advantage in remote regions with limited infrastructure.
The entire system runs on solar power, making it fully autonomous. Data is collected in a central microcomputer and visualized in Grafana, enabling experts in Europe to monitor the situation in the Pacific in real time.
The project has become not only a practical monitoring tool, but also a stepping stone toward long-term scientific cooperation and a clear demonstration of how Czech technology can support regions facing difficult terrain, extreme weather, or limited accessibility.

The system delivers:

• Autonomous collection of critical environmental and structural data
• Wireless transmission without the need for new cables
• Complete energy self-sufficiency thanks to solar power
• Online data access from anywhere in the world

Why this project matters

• It is a pilot IoT project for the entire university in Tonga, fostering future scientific and educational collaboration.
• It demonstrates how Czech technology can assist regions challenged by harsh conditions, extreme climates, or limited infrastructure.
• It shows how IoT can contribute to monitoring climate-change impacts on infrastructure and buildings.

The Tonga project illustrates how IQRF can unlock modern sensing capabilities even in the most remote locations.
