Three Frenchmen have won the STMicroelectronics STM32 Wireless Innovation design competition.

Cédric Jiminez from Chambéry, Alain Romaszewski from Amélie-les-Bains, and Balthazar Deliers from Sequedin developed projects based on the STM32 wireless microcontrollers.

The top three projects in the Europe wide competition were announced at the Embedded World show in Germany this week.

Claiming the €2,500 first prize was Cédric Jiminez, 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.

Alain Romaszewski wins the €1,500 second prize with a ZigBee Environmental Measurement Centre 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. The well documented project uses numerous external modules while sporting a neat 3D-printed case.

The third prize of €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 for home energy management.;;
