How It Works

Core Function

Babbeleaf is built around a simple idea: measure electrical micro-activity in plant tissue and render it as sound. This section walks through the core functions of the device from signal input to audio output.

Signal Collection

Each Babbeleaf unit includes multiple clip lead types that attach to a plant's stem, leaf, or root. These clips detect tiny fluctuations in voltage (typically < 300 microvolts) caused by ionic movement within the plant.

Amplification & Filtering

Because plant signals are weak, Babbeleaf includes a preamp circuit that amplifies the input before passing it to a signal processor. Low-pass and high-pass filters are applied to reduce noise and isolate usable signal ranges.

Signal Processing

A dedicated processor (not a general-purpose microcontroller) converts the analog signal to digital using an ADC (analog-to-digital converter). Real-time transformations shape the signal into a clean waveform suitable for playback or recording.

Output Options

Babbeleaf outputs mono audio by default but can optionally record in stereo (duplicated) format. Output is delivered via an internal speaker, 3.5mm stereo jack, or via Bluetooth if enabled.

Interface Control

All controls are available via a built-in web interface hosted by the device itself. Users can connect directly or join the device to a Wi-Fi network. From the browser, users can adjust gain, format, MIME type, and start/stop recording.
