Capacitive or Resistive soil/air moisture sensor. Microcontroller: (e.g., ESP32, Arduino Nano, or STM32). Power Supply: 3.3V - 5V DC.
If moisture falls below a pre-set threshold (e.g., 5. Safety & Maintenance Moisture_Detector_100.7z
If using resistive probes, regular cleaning is required to prevent oxidation. Capacitive or Resistive soil/air moisture sensor
