DC 5V soil moisture sensor relay control module for automatic irrigation Overview A relay driven module that uses soil moisture readings to control watering automatically. It switches connected valves or pumps on or off based on moisture level, enabling automated irrigation responsive to soil conditions. Why you need it - Automates irrigation decisions by using real time moisture data - Helps maintain proper soil moisture with minimal manual intervention - Stable operation powered by a 5V supply for reliable performance in typical setups Key attributes - Function: soil moisture sensing plus relay control to start or stop watering - Compatibility: designed for 5V systems and compatible controllers that drive the relay - Performance: reliable 5V operation suitable for integration into automated irrigation networks - Integration: acts as a practical module to connect moisture sensing with valve or pump control Use scenarios - Home garden: link to a valve or pump to water plants only when the soil dries beyond a set threshold - Greenhouse irrigation: automate drip or sprinkler systems to maintain consistent humidity levels - Planter boxes and balconies: simple, scalable solution for moisture based watering in limited spaces Notes - This module provides the core functionality for automated watering driven by soil conditions - It is intended as a component within a broader irrigation system and relies on compatible relays or actuators to operate water delivery.
