After several exciting months of competition, during which dozens of innovative projects were submitted, the 2024 STM32 Wireless Innovation Design Contest (presented by STMicroelectronics and Elektor) has crowned its top three winners after an intense period of evaluation. As luck would have it, three Frenchmen won the podium places: Cédric Jimenez from Chambéry, Alain Romaszewski from Amélie-les-Bains, and Balthazar Deliers from Sequedin. Congratulations to all of them for their hard work!

Winning STM32-Based Projects

After meticulous scrutiny, the judges announced the winners on April 10, 2024, at the STMicroelectronics booth (4A-148) during the embedded world 2024 trade fair. The top three winners emerged from the pool of exceptional entries, each bringing a unique perspective to the realm of wireless technology.

Claiming the prestigious First Prize (€2,500) was Cédric Jimenez, with his Open-Vario project: an open-source, multi-functional connected variometer for paragliding and hang gliding, equipped with features like GNSS positioning, accelerometer, temperature sensing, glide ratio computation, and flight data recording, all based on the STM32WB5MM-DK discovery kit. The judges were thoroughly impressed by the design, the features of the project, as well as the level of detail used by Cédric in the extensive documentation he wrote. Congratulations, Cédric for this well-deserved victory!

Alain Romaszewski wins the Second Prize (€1,500) with his ZigBee Environmental Measurement Center for indoor plants or greenhouses, using the STM32WB5MM-DK kit. It features sensors for monitoring soil humidity, temperature, ambient conditions, and CO2 levels, and includes automated watering and lighting systems based on these measurements, with data management via a server MQTT and Node-RED application. Well done, Alain, for this very well documented and skillfully designed project, which uses numerous external modules while sporting a neat 3D-printed case.

The Third Prize (€1,000) went to Balthazar Deliers for his Electric Meter that Matters, which integrates a Linky smart electricity meter with a smart home ecosystem using the Matter over Thread protocol, enabling real-time monitoring of power consumption via smartphone. The setup includes custom hardware for data conversion and connection to the STM32WB5MM-DK dev kit, software development in C/C++ and Python, and a smart home integration that visualizes energy usage. All of this demonstrates an innovative approach to home energy management. Well done!
