Soil moisture Sensor/Corrosion Resistance Probe

Corrosion-Resistant Probe Construction: Features specialized anti-corrosion trace plating designed to withstand prolonged exposure to wet soil, fertilizers, and mineral salts without oxidizing.

Dual Analog & Digital Signal Outputs: Equipped with an Analog Output (AO) pin for continuous moisture concentration readings and a Digital Output (DO) pin for direct threshold switching.

Onboard Voltage Comparator: Utilizes an onboard LM393 differential comparator IC to ensure stable, noise-free digital signal switching.

Adjustable Sensitivity Setpoint: Includes a built-in precision potentiometer to easily adjust the digital output trigger threshold for automated irrigation relays.

Integrated Visual Indicators: Outfitted with an onboard power LED and a digital output status LED for fast visual troubleshooting and status verification during deployment.

Board Material: Heavy-duty FR-4 glass-epoxy PCB with corrosion-resistant gold/tin-plated probe prongs and integrated LM393 control board.

Technical Specifications:

Sensor Type: Anti-Corrosion Resistive Soil Moisture Transducer.

Operating Supply Voltage: 3.3V – 5.0V DC.

Signal Outputs: Dual Analog (AO) + Digital Switching (DO).

Comparator IC: LM393 Differential Voltage Comparator.

Board Color: Blue Control PCB & Black/Gold Corrosion-Resistant Sensing Probe with Connecting Jumper Wire.

Usage Advice: Connect the probe to the control module using the included jumper wire; insert the probe prongs into the target soil matrix and wire AO to host ADC or DO to a relay control pin.

Maintenance: Keep the control board dry; periodically wipe mineral deposits or soil buildup off the corrosion-resistant prongs using a soft damp cloth.

Essential Long-Life Agricultural Probe: Position as a durable, budget-friendly soil moisture module engineered specifically to resist the rapid corrosion common in standard resistive soil sensors.

Highlight Anti-Corrosion Durability: Emphasize how the corrosion-resistant coating significantly extends operational lifespan in damp garden beds, greenhouse pots, and automated irrigation setups.

Recommended Cross-Sell Add-ons: Pair with Analog Capacitive Soil Moisture Sensor, ACEBOTT Soil Moisture Humidity Sensor Easy-Plug Compatible with ESP32/Arduino, 3-in-1 Integrated Sensor Temperature + Humidity + PH, and ESD antistatic mat 50x40CM PCB Welding Mat.
