Soil pH Sensor with Probe – Industrial Grade Soil Acidity Transducer

The Soil pH Sensor with Probe is a high-precision, industrial-grade soil testing transducer engineered for continuous and accurate monitoring of soil pH levels. Equipped with a rugged, corrosion-resistant electrode probe and an integrated signal transmitter module, it provides stable analog or digital outputs compatible with microcontrollers, PLCs, and IoT data loggers. It is an essential tool for smart farming, hydro-culture, and soil health analysis.

Key Features

• Accurate real-time soil pH measurement
• Corrosion-resistant and waterproof electrode probe design
• Integrated signal transmitter for stable output signal
• High measurement resolution and rapid response time
• Wide operating voltage range for flexible system integration
• Directly compatible with Arduino, ESP32, Raspberry Pi, and PLCs
• Suitable for long-term insertion in soil and aquatic media
• Low power consumption for remote IoT monitoring systems

Technical Specifications

Applications

• Smart agricultural irrigation and precision farming
• Greenhouse management and automated soil monitoring
• Botanical gardens, forestry, and turf health testing
• Soil research, environmental studies, and ecology monitoring
• Hydroponics, aquaponics, and potting soil measurement
• DIY IoT weather and soil stations with microcontrollers

Important Notes

• Ensure full contact between the probe tip and moist soil for accurate pH readings.
• Calibrate the sensor using standard pH buffer solutions (pH 4.01, 7.00, 10.01) prior to first use and periodically thereafter.
• Do not force the probe into hard or rocky ground to avoid damaging the electrode tip.
• Clean the probe with distilled water and dry it gently after taking measurements in abrasive soil.
• Do not submerge the signal transmitter circuit module in liquid unless explicitly IP68 rated.
