Description
Third Ear for Deaf Person is a smart wearable system designed using Nano Board that provides haptic (vibration) alerts to deaf individuals whenever a loud sound is detected. When the sound sensor picks up noise above a threshold, it activates red LEDs and a vibration motor. A green LED indicates the system is active.
The compact system is rechargeable using a TP4056 charging module and LiPo battery (402030). Ideal for academic use or as a social innovation prototype.
