Description

The sensor operates on the principle of electrical conductivity, where the resistance between its two probes varies with the soil’s moisture content. This change in resistance is converted into a corresponding analog voltage signal. A comparator circuit provides a digital output that toggles when the moisture level falls below a user-defined threshold, set via the onboard potentiometer.

Designed for long-term deployment, the corrosion-resistant metal probe ensures stable performance in various soil conditions without degradation. The module is engineered for seamless integration with common development boards and industrial control systems requiring soil hydration data.

Key Features

  • High-value build with a corrosion-resistant metal probe for reliable, long-term soil immersion.
  • Precise analog output for detailed moisture level monitoring and data logging.
  • Configurable digital output trigger for direct control of relays, pumps, or alarms.
  • Optimized performance-to-cost ratio for agricultural automation and smart gardening projects.
  • Compact and lightweight PCB design for easy mounting and deployment.
  • Simple 3-pin interface (VCC, GND, Signal) for quick prototyping and system integration.

Applications

  • Automated drip irrigation and sprinkler control systems in smart agriculture.
  • Soil moisture monitoring for greenhouse climate management and research.
  • Water conservation systems in residential gardens and landscaping.
  • Environmental data logging stations for agricultural research.
  • Plant health monitoring in automated indoor growing setups.

Frequently Asked Questions

What is the operating voltage range for this soil moisture sensor?

The module is designed to operate from 3.3V to 5V DC, making it directly compatible with most microcontrollers like Arduino Uno, ESP32, and Raspberry Pi GPIO (using 3.3V logic). Ensure your power supply can provide the ~15mA working current.

How do the analog and digital outputs work?

The analog output (typically the 'S' pin) provides a variable voltage signal proportional to the soil's moisture content, which can be read by an ADC pin. The digital output provides a high/low signal based on a moisture threshold, which is adjustable via the onboard potentiometer. You can use either output based on your project needs.

Is the probe suitable for long-term burial in soil?

Yes, the probe is constructed from corrosion-resistant metal specifically designed to withstand prolonged exposure to damp soil. For permanent installations, consider additional protective measures for the PCB module itself, such as a protective enclosure, to prevent water damage.
