RainSong is a solar-powered outdoor rain sensor that turns each raindrop into music on your phone. A piezo under a strike plate (the solar panel) is connected to a microprocessor (Seeed XIAO ESP32C3), which streams strength and timing of each raindrop over Bluetooth Low Energy. The Android app plays a wind-chime note within ~30–80 ms, then Muse Spark scores the rain and MusicGen builds a backing loop that follows intensity. Bringing AI into the garden. AI that knows the rain.
