Description

The HS-S33-L soil moisture sensor operates on a resistive sensing principle, where the electrical conductivity between its exposed electrodes varies with the moisture content of the surrounding soil. This change is converted into a clean digital signal output, simplifying data acquisition.

Designed for reliability in embedded systems, the module features a standard three-pin interface (GND, VCC, Signal) and is constructed on a durable PCB. Its low-power design and fast response time make it suitable for continuous monitoring in IoT and smart agriculture applications.

Key Features

  • Digital output provides noise-resistant signal for microcontroller compatibility.
  • Dual-supply voltage flexibility supports integration with both 3.3V and 5V logic families.
  • Low operating current (≤20 mA) enables efficient use in battery-powered nodes.
  • Compact and lightweight PCB construction allows for easy embedding in project enclosures.
  • PH2.0 connector ensures a reliable and secure electrical connection.
  • Fast response time (under 1 second) delivers real-time soil moisture feedback.

Applications

  • Automated drip irrigation control systems for home gardens and greenhouses.
  • Soil moisture monitoring nodes in IoT-based smart agriculture and precision farming.
  • Educational kits for teaching embedded systems and environmental sensing principles.
  • Plant health monitoring in automated indoor Grow boxes and hydroponic setups.

Frequently Asked Questions

What is the operating voltage range for the HS-S33-L sensor?

The HS-S33-L is designed to operate at either 3.3V or 5V DC. You must connect it to one of these standard voltages via its VCC pin. Ensure your power supply matches your chosen logic level for proper digital signal output.

How do I connect the HS-S33-L to an Arduino or microcontroller?

Connect the module's three pins: VCC to 3.3V or 5V on your board, GND to ground, and the Signal pin to any digital input pin on your microcontroller. The digital output can be read directly using a standard `digitalRead()` function or similar GPIO library.

Does this sensor provide an analog or digital output?

The HS-S33-L provides a digital output signal. It internally processes the resistive measurement from its probes and outputs a high/low logic level, simplifying code by eliminating the need for an ADC (Analog-to-Digital Converter) on your microcontroller.

What is the response time and power consumption of this sensor?

The sensor has a fast response time of less than one second to changes in soil moisture. Its working current is ≤20 mA, making it suitable for low-power, battery-operated monitoring systems commonly used in remote IoT applications.
