Soil moisture sensor
Automate plant watering, monitor greenhouse conditions, and prevent overwatering using this complete Soil Moisture Sensor Module.
Guessing soil dryness often causes overwatering or underwatering in garden automation systems. However, this high-sensitivity YL-69 Soil Moisture Sensor Module provides an active hardware solution for real-time soil telemetry. It utilizes two conductive metallic prongs that measure electrical resistance through the surrounding earth. Consequently, you can actuate automated water pumps or send mobile alerts immediately when soil becomes dry.
Key Features:
Conductive Two-Prong Soil Probe: It features a dual-leg PCB probe designed for insertion into soil or growing media. Because of these exposed conductive traces, current passes through the soil to detect exact volumetric wetness.
Dual Output Signal Capability: The driver board provides both AO (analog output) and DO (digital output) pins. Therefore, you can track smooth analog humidity curves or receive simple binary dryness signals.
Onboard Sensitivity Trimmer Potentiometer: It features a multi-turn rotary potentiometer tied to an LM393 comparator. Furthermore, this trimmer allows precise tuning of the digital switching point for dry or moist dirt.
Modular Two-Piece Layout: The probe connects to the driver module via flexible jumper wires. Simply keep sensitive control electronics safely above ground while burying the sensing probe deep in soil.
Why should you choose this soil moisture sensor module? Are you constructing automated greenhouse irrigator kits, designing smart potted plant monitors, or teaching IoT environmental science? Because of its dual-output design, reading moisture percentage requires only a standard ADC channel. Moreover, triggering external relay modules directly via digital outputs simplifies standalone automation circuits. Furthermore, it offers low power consumption and easy mounting for students, makers, and agricultural innovators alike. Therefore, it is an essential sensor for automated plant care projects. Simply connect the four-pin header to start automating your irrigation system today.
