Closed-Loop Plant Bio-Dome

3-axis gantry delivering targeted water, nutrients, or light from plant signals. 3-axis gantry delivering targeted water, nutrients, or light from plant signals.

Components

• ESP32/MCU
• soil, sap-flow or optical sensors
• gantry axes
• pumps/lights

Build steps

1. Inventory the board, actuators, sensors, and power rails listed for F04.
2. Build and inspect the low-voltage wiring against the supplied connection diagram before connecting actuators.
3. Flash the firmware, run the startup self-check, and record the printed board and firmware version.
4. Calibrate the sensors and limits, then run the acceptance tests at the lowest safe energy level.

Test and expected result

Baseline one plant, calibrate sensors, change one variable at a time, and log response.

Safety and limits

Prototype only; no claims of agricultural or medical efficacy.
