Indoor Garden Irrigation Node

Moisture-aware pump controller for a small indoor growing system. Moisture-aware pump controller for a small indoor growing system.

Components

  • MCU
  • soil probes
  • pump/MOSFET
  • reservoir sensors

Build steps

  1. Inventory the board, actuators, sensors, and power rails listed for S07.
  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

Calibrate soil probes, dose a known volume, detect dry-run, and isolate water from logic power.

Safety and limits

Use drip loops and isolated low-voltage power.
