This water level sensor detects liquid depth and presence through exposed parallel traces, providing analog output for precise measurement. The red PCB module is ideal for water tanks, irrigation systems, and leak detectors, with corrosion-resistant nickel plating for durability.
Key Benefits
✔ Analog Output – Measures water depth (0–5V)
✔ Corrosion-Resistant – Nickel-plated traces
✔ No Moving Parts – Solid-state reliability
✔ Easy Installation – Mount vertically/horizontally
