Introduction

Welcome to the SensEdu documentation!

SensEdu is an ultrasonic ranging and detection development shield for Arduino GIGA R1, designed as an open-source educational project to lower the barrier to ultrasonic sensing and research.

Based on the STM32H747 Microcontroller and runs on the Arduino GIGA R1 WiFi development Board, providing industry-standard embedded development experience while remaining beginner-friendly. SensEdu is perfect for students looking for a smooth introduction to this field, offering an easy-to-understand yet highly modifiable software and hardware environment.

This project is completely open source and comes with quick support from the development team.

If you like the project, consider contributing. Any input from both experienced developers and beginners is highly appreciated!

Features

SensEdu includes:

4x MEMS microphones, sensitive well into the ultrasonic range
2x Ultrasonic transducers with a ~33 kHz center frequency
4x Dual-channel instrumentation amplifiers
Barometric air pressure sensor
Humidity & temperature sensor

You can find detailed information about each component in the PCB Chapter. With these components, you can build a variety of projects, such as:

Pulse-Echo and FMCW ultrasonic ranging
Ultrasonic 3D Tracking
Ultrasonic chirp generation
Doppler Velocimeter
FSK communication
Audio recorder
EMG controls
Weather Station

Many of these are already fully implemented and documented in the Projects chapter.

Where to Start

Follow the Getting Started guide to mount the shield, install the Arduino board package and the SensEdu library, and upload your first sketch. If something does not work as expected, the Help section collects the most common issues.
