Description

The HS-S09PC 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 soil. This change is converted into a clean digital output signal, simplifying integration with control systems.

Designed for embedded and IoT applications, the module features a standard three-pin interface (GND, VCC, Signal) terminated with a reliable PH2.0 connector. Its compact form factor and low power requirements make it suitable for deployment in battery-powered field nodes and DIY smart gardening projects.

Key Features

  • Digital Output: Provides a high/low signal for straightforward logic-level reading, eliminating the need for ADC calibration.
  • Wide Voltage Compatibility: Supports both 3.3V and 5V microcontroller ecosystems, including Arduino, ESP32, and Raspberry Pi.
  • Optimized Performance-to-Cost Ratio: Delivers reliable moisture detection in a simple, durable PCB construction.
  • Fast Response Sensing: Reacts to soil moisture changes in under one second for real-time system feedback.
  • Secure Connection Interface: Utilizes a PH2.0 2/3P terminal connector for a reliable and detachable wiring solution.
  • Low Operational Current: Consumes ≤20mA, making it suitable for solar-powered or battery-operated monitoring stations.

Applications

  • Automated drip irrigation control systems for home gardens and greenhouses.
  • Soil moisture monitoring nodes in wireless IoT agriculture and precision farming networks.
  • Educational kits for teaching plant biology and embedded system programming with Arduino or micro:bit.
  • Overwatering prevention systems for potted plants and indoor horticulture setups.

Frequently Asked Questions

What is the output signal type of the HS-S09PC sensor?

The HS-S09PC provides a digital output signal. It outputs a logic HIGH or LOW level based on a predefined soil moisture threshold, making it simple to read directly from a microcontroller's digital input pin without requiring an analog-to-digital converter (ADC).

What microcontrollers or development boards is this sensor compatible with?

This sensor is compatible with any 3.3V or 5V logic microcontroller. It works seamlessly with popular platforms like Arduino Uno (5V), Arduino Nano, ESP32 (3.3V), Raspberry Pi Pico, and STM32 boards. Ensure you connect the VCC pin to the corresponding voltage level of your board.

How do I wire and connect the HS-S09PC sensor?

Connect the sensor's three pins using the PH2.0 connector: VCC to your board's 3.3V or 5V power supply, GND to ground, and the Signal (S) pin to any digital input pin on your microcontroller. The module includes a comparator circuit to generate the digital signal based on soil conductivity.
