sensing

listening at
the microvolt
level.

two stainless steel electrodes make gentle contact with your plant’s stem or leaves. they measure bioelectric impedance — the plant’s internal resistance to a tiny oscillating signal.

this isn’t a soil sensor pretending to make music. it’s a direct reading of your plant’s electrical state.

methodbioelectric impedance

sampling100ms intervals

signal chain

from biology
to MIDI.

an NE555 timer circuit generates a precision oscillating signal. the plant’s impedance modulates it. an ESP32-S3 with 16MB flash and 8MB PSRAM samples the result and maps it to MIDI parameters: pitch, velocity, modulation, timing.

oscillatorNE555 astable circuit

processorESP32-S3 / dual-core / 240MHz

scales13 musical scales, 4 presets

mappingsame signal, same note. no fakery.

connectivity

plug in
anywhere.

USB MIDI connects directly to any DAW — ableton, logic, bitwig, you name it. BLE 5.0 sends wireless MIDI to your phone, tablet, or any bluetooth-capable synth. wifi streams data to the companion app. three protocols. zero drivers. works the moment you plug it in.

01USB MIDI

plug into any DAW. class-compliant. zero drivers. TinyUSB composite CDC + MIDI.

02BLE 5.0

wireless MIDI to phone, tablet, or any bluetooth-capable synth. low-latency.

03WiFi

streams to the companion app via websocket. real-time sensor dashboard. OTA firmware updates.

built-in audio

no laptop
needed.

T1N-P0T includes a PCM5102A DAC running at 44.1kHz / 16-bit stereo and an 8-voice polyphonic synthesizer. plug in headphones or a speaker and your plant is performing live.

a 1.69-inch IPS LCD shows real-time data: current note, scale, signal strength, soil moisture, light level. a rotary encoder navigates every menu. a NeoPixel LED ring provides ambient status at a glance.

if it takes more than three clicks, we redesigned it.
