XKC-Y26-V Non-contact Water Liquid Level Induction Switch Detector Sensor 5-12V DC

The XKC-Y26-V can detect liquid levels through non-metallic container walls, but performance depends on the material's dielectric properties. For common plastics like ABS or PVC, typical maximum effective thickness is up to 10mm. Sensitivity decreases with thicker walls or materials with higher dielectric constants.

Connect the sensor's red wire to 5V-12V DC, black wire to GND, and the signal (typically yellow or blue) wire to any digital input pin on the Arduino. The output is a TTL-level signal: HIGH (near Vcc) when liquid is detected, LOW (near 0V) when absent. Use a simple digitalRead() function in your sketch.

No, the XKC-Y26-V uses capacitive sensing which is blocked by conductive materials like metal. It is specifically designed for non-metallic containers only, such as plastic, glass, ceramic, or composite tanks. For metal tanks, a contact-based or ultrasonic sensor would be required.

The sensor detects any liquid that changes the dielectric constant behind the container wall, including water, acids, alkalis, oils, and chemicals. It is unaffected by the liquid's color, transparency, or the presence of suspended solids, making it suitable for wastewater, chemical processing, and food-grade applications.
