DC 3.3-12V Soil Moisture Detector Module

DC 3.3-12V Soil Moisture Detector Module Corrosion Resistance Probe

The DC 3.3–12V Soil Moisture Detector Module with a corrosion-resistant probe is an essential sensor for monitoring soil moisture levels in gardening, agriculture, and environmental sensing projects. Designed to be compact, affordable, and easy to integrate, this module helps users detect whether soil is dry, moist, or wet, enabling automation in watering systems and optimizing plant care.

Operating on a voltage range of 3.3V to 12V, the module is compatible with most development boards, such as Arduino, Raspberry Pi, ESP8266, and ESP32, making it a popular choice for DIY electronics enthusiasts and professionals alike. The built-in corrosion-resistant probe ensures durability, allowing the module to function reliably even with extended exposure to wet soil.

The sensor works by measuring the electrical conductivity between two metal prongs on the probe. Moist soil conducts electricity better than dry soil, and this difference is converted into an analog signal that represents the moisture level. The module also features a digital output that can be triggered when the moisture level crosses a certain threshold, which can be adjusted using an onboard potentiometer.

With dual outputs (analog and digital), users can either measure precise moisture values or trigger events like activating a pump, buzzer, or sending notifications. The module is ideal for automated irrigation systems, plant monitoring, greenhouse automation, and educational projects related to smart farming.

Thanks to its simplicity and wide voltage compatibility, the DC 3.3–12V Soil Moisture Sensor is perfect for beginners and advanced users looking to build intelligent gardening systems. Its anti-corrosion design makes it more reliable than basic probes, ensuring consistent performance over time in outdoor or humid conditions.

Features:
