The sensor compensates for residual films, moisture, or foam in liquids such as milk, honey, latex, blood, engine oil, and acid\/alkaline solutions, delivering reliable level detection. A built‑in LED indicator shows real‑time status, and the IP67‑rated PC‑V0 housing ensures stable operation in harsh industrial or outdoor environments. This sensor works seamlessly with Arduino and other 5V logic microcontrollers.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0668\/0641\/5437\/files\/E38023-content1.webp?v=1791345368\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOne‑Touch Automatic Sensitivity Calibration\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe sensor features an intelligent sensitivity memory function with external push‑button control. Simply ensure liquid is present at the sensing position and single‑click the button. Within 3‑5 seconds, the sensor automatically locks onto the optimal sensitivity for the current container wall thickness and material. This eliminates manual tuning and adapts to plastic, glass, or ceramic containers up to 10mm thick.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eNon‑Contact Detection for Demanding Liquids\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eBecause the sensor mounts on the outer container wall, it never touches the measured liquid. This avoids corrosion from strong acids or alkalis, prevents contamination in medical or food applications, and eliminates fouling from sticky substances like honey, latex, or engine oil. The non‑contact design also simplifies cleaning and maintenance in hygienic environments.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePenetrates Non‑Metallic Containers with High Sensitivity\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe advanced capacitive sensing technology works through plastic, glass, and ceramic walls with a sensing distance (wall thickness) up to 10mm. It detects low‑conductivity liquids (≤50ms) and compensates for residual moisture or foam that would confuse ordinary sensors. The built‑in high‑precision IC converts minute capacitance changes into a reliable high\/low level signal.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIndustrial‑Grade Robustness\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe housing is molded from PC‑V0 fire‑retardant material, and the IP67 waterproof rating protects against dust and temporary immersion.
