Presentation:

The HydraoExp2 is a connected educational test bench that allows students to study water management and energy efficiency through an instrumented hydraulic circuit.

It combines real measurements, modeling, and a mobile app to raise awareness about responsible water use.

Technical solutions covered:

• Hydraulic flow management and measurement: study of flow rate, pressure, and water consumption using sensors and a flow meter.
• Energy conversion: transformation of hydraulic energy into electrical energy using a turbine.
• Data acquisition and processing: use of a microcontroller board (Arduino/Python) to collect and analyze measurements.
• Wireless communication: transfer of data to a mobile application via Bluetooth Low Energy.
• Smart visual indication: light-up shower head indicating water consumption in real time.
• Multiphysics modeling: simulation of hydraulic and energy behaviors using Matlab/Simulink/Simscape.

Educational activities:

• Getting started with the system: identification of components, measurement of physical quantities (flow rate, pressure, energy).
• Functional analysis and modeling: creation of SysML diagrams, modeling of the hydraulic circuit, and experimental validation.
• Energy study: calculation and comparison of hydraulic, mechanical, and electrical power.
• Programming and data acquisition: use of sensors via Arduino or Python.
• Communication and IoT: implementation of Bluetooth connection between the test bench and the mobile application.
• Eco-responsible project: reflection on reducing water consumption and sustainable development.

Key features:

Comprehensive, interdisciplinary approach: combines hydraulics, energy, electronics, and digital technology.
Turnkey teaching support: documentation, simulation models, and ready-to-use programs.
Real and connected measurements: data acquisition via sensors and monitoring on a mobile app.
Awareness of sustainable development: practical learning about rational water management.
Broad educational compatibility: can be used from high school (STI2D, SNT, SI) through to higher education.
Motivating and interactive tool: real-time visualization (shower head lighting, Bluetooth data)
