Capacitive or Resistive soil/air moisture sensor. Microcontroller: (e.g., ESP32, Arduino Nano, or STM32). Power Supply: 3.3V - 5V DC.
Re-calibration is recommended every 6 months to account for sensor drift. Moisture_Detector_100.7z
If using resistive probes, regular cleaning is required to prevent oxidation. Capacitive or Resistive soil/air moisture sensor
