Description

The HS-S09-LC Soil Moisture Sensor operates on a resistive sensing principle, where the electrical conductivity between its exposed PCB traces varies with the moisture content of the surrounding medium. This change in resistance is converted into a proportional analog voltage signal (A) for precise measurement, while a digital output (D) provides a threshold-based signal for simple on/off detection, ideal for triggering alerts or irrigation systems.

Built on a durable FR4 PCB, the module is designed for low-power operation with a working current of ≤20mA, making it suitable for battery-powered applications. Its fast response time ensures immediate feedback for dynamic environmental monitoring, from garden automation to educational science projects.

Key Features

  • Dual-output interface provides both precise analog readings and configurable digital triggers.
  • Broad voltage compatibility supports seamless integration with 3.3V and 5V microcontroller platforms.
  • Low-power design with ≤20mA operating current for energy-efficient, long-term deployments.
  • Fast-responding sensing element delivers real-time data with ≤100ms response time.
  • Robust FR4 PCB construction ensures reliable performance in moist soil environments.
  • Standardized PH2.0 connector simplifies wiring and reduces connection failures.
  • Compact footprint allows for installation in tight spaces within planters or sensor arrays.
  • High-value build optimized for cost-effective soil moisture monitoring solutions.

Applications

  • Automated drip irrigation control systems in smart gardens and greenhouses.
  • Soil moisture monitoring for precision agriculture and crop yield optimization.
  • Environmental data logging in weather stations and climate research projects.
  • Plant health and overwatering/underwatering alert systems for indoor horticulture.
  • Educational kits for teaching soil science and basic sensor interfacing with Arduino.

Frequently Asked Questions

What is the operating voltage range for the HS-S09-LC sensor?

The HS-S09-LC operates from 3.3V to 5.5V DC, making it directly compatible with both 3.3V logic systems (like ESP32 or Raspberry Pi) and standard 5V Arduino boards without requiring a logic level converter.

How do I connect and use the analog vs. digital outputs?

Connect the module's V and G pins to power and ground. The analog output (A) provides a variable voltage proportional to moisture, which should be read by an MCU's ADC pin. The digital output (D) provides a high/low signal based on a preset moisture threshold, useful for simple triggers. Both outputs are accessible via the PH2.0 connector.

Is this sensor suitable for long-term burial in soil?

While the FR4 PCB is durable, the exposed electrodes are susceptible to corrosion and electrolysis over extended periods. For permanent installation, consider using a sensor with corrosion-resistant probes or applying a protective coating. For short-term monitoring and prototyping, it is perfectly suitable.
