The Soil Moisture Sensor Module is a two-part hygrometer that pairs a corrosion-resistant probe with an LM393-based comparator board to measure the moisture level in soil. It is widely used in automatic plant watering systems, greenhouse monitoring, and simple agricultural projects.

Key features:

  • Dual Output: Provides a digital output (D0) that switches at a set threshold and an analog output (A0) for a continuous moisture reading.
  • Adjustable Sensitivity: An onboard potentiometer sets the digital trigger threshold to match different soil types.
  • LM393 Comparator: Uses a stable LM393 voltage comparator IC for consistent, low-noise digital switching.
  • Corrosion-Resistant Probe: The nickel-plated fork probe resists oxidation from prolonged soil contact.
  • Power Indicator LED: An onboard LED confirms the module is powered and shows the digital trigger state.
  • Wide Compatibility: Works directly with Arduino, ESP8266, ESP32, and other 3.3V/5V microcontrollers.

Simply insert the probe into the soil and connect the module to a microcontroller to start monitoring moisture levels in real time.
