This capacitive soil moisture sensor provides reliable, longlasting soil moisture detection for garden plants and smallscale irrigation setups. Its design and electronics reduce common sensor problems while remaining compatible with a wide range of control systems. Key benefits Accurate soil measurements: Uses capacitive sensing technology to provide precise soil moisture detection for healthier plants and more consistent irrigation decisions. Stable operation across voltages: Builtin voltage stabilizing chip allows operation from 3.3 to 5.5 volts, making the sensor compatible with many microcontroller and control systems. Reduced corrosion and false readings: The capacitive induction design avoids the metal corrosion and unstable readings often found with resistive probe sensors, improving reliability over time. Simple integration: Designed for straightforward use with garden controllers, automated watering systems, and hobby electronics that operate within the supported voltage range. Features and performance Sensing method: Capacitive induction capacitive sensing for noninvasive and consistent soil moisture detection. Voltage compatibility: Supports 3.3 to 5.5 volts through an internal stabilizing chip for stable output under variable supply conditions. Reliability: Design reduces common failure modes of alternative sensors, offering more consistent data and longer service life. Practical applications Home gardening: Monitor soil moisture in outdoor garden beds and potted plants to avoid overwatering or underwatering. Automated watering systems: Integrate with irrigation controllers or microcontrollerbased systems to trigger valves or pumps when soil moisture crosses set thresholds. Seedling and greenhouse use: Track moisture in seedling trays and small greenhouse zones to maintain ideal growing conditions. Why customers choose this sensor It delivers accurate, repeatable soil moisture readings without the corrosion problems associated with exposed metal probes. Broad voltage support and internal stabilization simplify connection to a variety of control boards and systems. The capacitive induction approach yields stable measurements across different soil types and environmental conditions. Compatibility and integration tips Works with controllers and microcontroller boards that provide 3.3 to 5.5 volts. Check your system voltage before connecting. For results, place the sensing element at root zone depth and avoid direct contact with fertilizer salts or conductive materials that may affect readings. This sensor is suited for gardeners, DIY electronics users, and anyone looking to add reliable soil moisture feedback to irrigation or plant care systems without the maintenance issues of traditional resistive probes.
