The Silent Wind

Purpose

Wind is the invisible, but it clearly touches our bodies. To enable us to feel the invisible, this project uses light and motion as alternative expressions.

Concept

“Giving shape to the invisible” — transforming the unseen into something we can feel, through technology and the sensibility of Japanese culture.

Components

🌬️The Anemometer (ESP32DevKitC)

Detects wind and sends the data to the scarf.

🧣The Scarf (ESP32DevKitC)

Receives wind data from the anemometer, sends it to the earring, and controls a servo motor.

💍The Earrings(nRF52832)

Receive wind data from the scarf and controls LED blinking.

System Overview
