Product Description

Soil Moisture Sensor Module for Arduino

Reliable Plant Moisture Detection for Smart Gardening and Irrigation Projects

This soil moisture sensor measures water content in soil, providing essential data for automated plant watering systems and smart gardening projects. Compatible with Arduino and similar microcontroller boards, it offers a simple solution for monitoring plant health and automating irrigation.

Easy Soil Moisture Detection - Provides analog output proportional to soil water content
Compatible with Arduino and 5V/3.3V systems - Wide operating voltage range for flexible use
For resistive sensors, connect VCC to 5V (or 3.3V), GND to ground, and AO to an analog input pin on your microcontroller [citation:3][citation:4][citation:12].
For longterm use, capacitive sensors are more corrosionresistant and durable than resistive types [citation:6][citation:11].

Troubleshooting

Inconsistent readings:

  • Calibrate the sensor for your specific soil type by noting readings in dry and wet conditions [citation:4][citation:15].
  • Avoid exposing the electronic components to moisture.
  • Clean sensor probes if oxidation or debris buildup occurs [citation:3][citation:4].

No output:

  • Check wiring connections (VCC, GND, AO).
  • Verify power supply (3.3V to 5.5V) is stable.
  • Ensure the sensor is correctly inserted into the soil.
