CAPACITIVE SOIL MOISTURE

Precision Capacitive Soil Moisture Sensor – Rapid, Reliable Soil Analysis

This capacitive sensor delivers accurate volumetric water content readings without altering the soil structure. Using non-contact dielectric measurement, it detects changes in soil moisture through variations in capacitance, providing real‑time data for both agricultural and laboratory environments. The sensor’s low‑power design and wide scalability make it ideal for precision irrigation, greenhouse automation, and smart‑farm monitoring systems.

• Operating Voltage: 3.3 V / 5 V DC
• Measurement Range: 0 % to 70 % volumetric water content (VWC) with ±2 % accuracy
• Response Time: < 0.5 s per readout, enabling rapid feedback loops
• Common Use Case: Dual‑port irrigation control in commercial crop fields and precision hydroponic systems
