Projects developed with SensEdu

The following section documents select projects developed by SensEdu contributors. These real-world examples demonstrate practical use cases of the platform and highlight its capabilities.

Currently, this section is the main focus of our team. We aim to expand our collection of polished, fully documented projects to better illustrate SensEdu applications. Contributions are highly welcomed! If you’ve created a nice project, please consider adding it to both this wiki and our main repository by following these guidelines.

Most of the projects utilize SensEdu library, but it is not explicitly necessary, you can develop projects with standard or other custom Arduino GIGA R1 libraries.

As detailed in the PCB specifications, all applications center around three core hardware components:

  • MEMS microphones
  • Barometric Air Pressure Sensor
  • Ultrasonic Transducers

Ultrasonic Transceiver

SensEdu’s primary functionality lies in its ultrasonic transceiver capabilities. The system pairs 32 kHz ultrasonic transmitters (speakers) with high-sensitivity MEMS microphones optimized for 10-100 kHz reception (32 kHz resonant frequency). This combination enables implementations such as:

  • Distance measurements
  • Collision avoidance systems
  • Robotic navigation
  • Radars
  • Radio communication

Barometric Pressure Sensor

Moreover, the board is equipped with a barometric sensor which enables atmospheric measurements. It could be utilized for:

  • Elevation tracking (climbing\descent detection)
  • Environmental monitoring systems
  • Motion pattern recognition (e.g., falling)
  • Robot vertical navigation

General Purpose Instrumentation Amplifiers

SensEdu is equipped with extra x2 dual-channel amplifiers AD8222. Their inputs are wired to headers, making them suitable for any application that requires a simple Amplification → ADC signal path. This is the final piece that makes SensEdu an excellent tool for basic sensor systems education, enabling a wide range of projects such as:

  • Various bio-signals projects, e.g., Electromyography (EMG)
  • Strain Gauge Measurements
  • Thermocouple Measurements
