01 / THE QUESTION
What needed to be understood?
Audible household alarms can be inaccessible to people with hearing impairments. This project develops a device that recognizes selected alarm frequencies and provides a visual LED alert.
- Alarm recognition
- Visual feedback
- Embedded control
- Inclusive design
02 / THE APPROACH
From model to interpretation.
Identify relevant alarm-frequency patterns using a microphone sensor.
Apply signal processing to distinguish critical alarms from background noise.
Integrate microcontroller logic and visual feedback, with real-time response and low power as design goals.
03 / MY CONTRIBUTION
The work I brought to the project.
Sensor integration, signal processing and embedded control for an accessibility-focused device. The project demonstrates the connection between a human need and a practical mechatronic system.
