Description

The HS-S09-LB Raindrop Sensor operates on a conductivity sensing principle, where the presence of water droplets on its exposed parallel traces completes an electrical circuit, altering the output signal. This change is processed internally to provide both a raw analog voltage and a threshold-based digital signal, enabling precise moisture level measurement or simple rain/no-rain detection.

Designed for integration into weather stations, smart agriculture systems, and IoT environmental monitors, the module’s low power consumption (≤20mA) and compact form factor make it suitable for portable and fixed installations. Its straightforward interface allows for immediate connection to analog-to-digital converters (ADCs) or digital input pins on microcontrollers and single-board computers.

Key Features

  • Dual-Output Interface: Provides both analog (A) and digital (D) output pins for maximum flexibility in data acquisition and system design.
  • Broad Voltage Compatibility: Supports a 3.3V to 5.5V DC supply, ensuring seamless operation with 3.3V logic microcontrollers and standard 5V Arduino boards.
  • Fast-Response Sensing: Features a rapid ≤100ms response time for immediate detection of rainfall onset and changes in moisture levels.
  • Optimized Compact Design: Built on a durable FR4 PCB with a minimal 23mm x 33mm footprint for easy integration into space-constrained projects.
  • Standardized Connector: Utilizes a PH2.0 2/3P terminal wire interface for reliable and secure electrical connections.
  • Low Operational Current: Consumes ≤20mA during operation, making it suitable for battery-powered and energy-efficient applications.

Applications

  • Automatic weather station precipitation detection and logging systems.
  • Smart agriculture and irrigation control systems for moisture-based watering.
  • Vehicle windshield wiper automation and rain-sensing modules.
  • Home automation and IoT projects for leak detection or window status monitoring.
  • Educational electronics kits for teaching environmental sensing principles.

Frequently Asked Questions

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

The HS-S09-LB operates from 3.3V to 5.5V DC. This range makes it directly compatible with both 3.3V logic platforms like ESP32 or Raspberry Pi and standard 5V Arduino boards without requiring a level shifter.

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

Connect the module's V and G pins to power and ground. The analog (A) output provides a variable voltage proportional to moisture on the sensing plate, which should be read by an ADC pin on your microcontroller. The digital (D) output provides a high/low signal based on an adjustable threshold, typically set by a potentiometer on the module, and can be connected to any digital input pin.

What is the purpose of the PH2.0 interface, and what cable do I need?

The PH2.0 2/3P interface is a small, polarized connector that ensures proper wiring orientation. You will need a matching PH2.0 female connector cable with 2 or 3 pins (often sold as Jumper wires) to connect the sensor to a breadboard or microcontroller header pins. The standard pinout is VCC, GND, and the output signals.
