Soil Moisture Sensor

Resistive Moisture Probing Matrix: Utilizes dual exposed PCB prongs to measure variations in soil conductivity, providing continuous volumetric moisture estimation.

Dual Analog & Digital Logic Signals: Features an Analog Output (AO) pin for variable voltage measurement alongside a Digital Output (DO) pin for direct threshold switching.

Onboard Signal Comparator: Integrates an onboard LM393 differential comparator IC to ensure crisp, chatter-free digital switching outputs.

Adjustable Threshold Sensitivity: Includes an onboard multi-turn precision potentiometer to fine-tune digital trigger levels for automated irrigation relays and pumps.

Integrated LED Status Indicators: Features dedicated onboard LEDs for power indication and digital output switching status for fast visual debugging.

Board Material: FR-4 glass-epoxy probe PCB with tinned/plated sensing prongs and separate LM393 control board.

Technical Specifications:

Sensor Type: Resistive Soil Moisture Transducer.

Operating Voltage: 3.3V – 5.0V DC.

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

Comparator IC: LM393 Differential Comparator.

Color: Blue Control PCB & Black Probe with Jumper Interconnect Cable.

Usage Advice: Connect probe prongs to the control module; wire VCC (3.3V-5V) and GND, then connect AO to your microcontroller's ADC or DO to a relay control pin.

Maintenance: Keep the upper control module completely dry; clean soil crust or oxidation off the probe prongs periodically to ensure accurate readings.

Essential Beginner Agricultural Module: Position as the classic, budget-friendly entry sensor for DIY plant watering projects, Arduino garden kits, and basic soil monitoring setups.

Highlight Dual-Output Flexibility: Emphasize how having both analog continuous tracking and digital relay switching makes it versatile for simple stand-alone circuits or microcontrollers.

Recommended Cross-Sell Add-ons: Pair with Analog Capacitive Soil Moisture Sensor, Soil moisture Sensor/Corrosion Resistance Probe, ACEBOTT Soil Moisture Humidity Sensor Easy-Plug Compatible with ESP32/Arduino, and ESD antistatic mat 50x40CM PCB Welding Mat.
