XKC-Y25 NPN Non-Contact Liquid Level Sensor for Water Tanks & Pipes
XKC-Y25 NPN Intelligent Non-Contact Liquid Water Level Sensor (5-24V, Non-Metal Tank Detection)
The XKC-Y25 is a capacitive non-contact liquid level sensor that detects water presence through plastic, glass, or ceramic walls without direct fluid contact. It outputs an NPN signal (low when liquid detected) suitable for microcontrollers and control circuits. Ideal for water tanks, pipelines, and automatic water level control systems.

What You Can Build With This
- Water level indicator with LED or LCD display
- Automatic water pump controller for overhead tanks
- Tank overflow alarm with buzzer and relay
- Pipe burst detection by monitoring flow at multiple points
Compatibility
Works with 3.3V and 5V logic microcontrollers like Arduino, ESP8266, ESP32, Raspberry Pi (with voltage divider). Output is open-collector NPN, requires pull-up resistor to VCC. Connect signal pin to digital input.
Wiring Notes
Connect red wire to VCC (5-24V DC), black wire to GND, yellow wire to digital input pin. Add a 10kΩ pull-up resistor from yellow wire to VCC if microcontroller internal pull-up is insufficient. Ensure sensor face is tightly attached to the non-metal container wall.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the NPN output can be read directly by Arduino digital pins. Connect with a 10kΩ pull-up resistor and detect LOW when water is present.
Can it detect water through metal pipes?
No, it works only through non-metallic materials like plastic, glass, or ceramic. Metal interferes with capacitive sensing.
What is the maximum sensing distance?
Up to 13mm through a non-metal barrier, but this reduces with thicker or denser materials. Ensure the sensor face is flush against the container.
