AJMRTC soil moisture meter detection module with relay is a practical expansion board designed for soil humidity monitoring and automatic irrigation control. This module combines soil moisture sensing unit and relay control circuit allinone, which detects realtime soil humidity level and triggers relay action when humidity reaches preset threshold, to turn on or off water pumps and solenoid valves automatically. Builtin adjustable potentiometer allows you to calibrate trigger sensitivity conveniently to match different soil types such as sandy soil, loam and clay soil. It provides both analog signal output for humidity value reading and digital switching output, compatible with various microcontroller development boards. The onboard relay offers reliable loadswitching capability, removing complicated external driving circuits for your DIY irrigation setup. Compact layout simplifies wiring and hardware assembly. Widely adopted for potted plant care, greenhouse planting, garden irrigation and agriculturalrelated maker projects. Please pay attention to probe installation depth and avoid longterm probe immersion in water to extend service life.
