Features

  1. Uses our high-quality soil sensor for moisture detection. The probe surface is nickel-plated and features a widened sensing area to improve conductivity and reduce corrosion from soil contact, extending service life.
  2. Wide-range soil moisture control. A potentiometer adjusts the threshold: when moisture is below the setpoint the digital output (DO) is HIGH; when above the setpoint DO is LOW.
  3. Comparator: LM393 for stable operation.
  4. Operating voltage: 3.3 V – 5 V.
  5. Mounting holes for easy installation.

  6. PCB size: 32 mm × 14 mm.
