XKC-Y25-V Non-Contact Liquid Level Sensor | 5V Digital Output
XKC-Y25-V Intelligent Non-Contact Liquid Water Level Sensor with 5V Digital Output
The XKC-Y25-V is a capacitive non-contact liquid level sensor that detects water and other liquids through non-metallic container walls, up to 12mm thick, without any direct fluid contact. It outputs a simple digital high/low signal when liquid is present, making it perfect for automated tank monitoring, overflow prevention, and IoT water management projects.

- Non-invasive aquarium water level monitor
- IoT overflow alarm system for overhead tanks
- Automated plant watering system with soil moisture detection via container
Compatibility
This sensor works with any microcontroller that accepts 5V digital inputs, including Arduino Uno, Mega, Raspberry Pi (with level shifting), ESP32, and NodeMCU. It requires a 5V power supply and connects directly to a GPIO pin for reading the logic state.
Wiring Notes
Connect VCC to 5V, GND to ground, and the OUT pin to a digital input. The sensor has an onboard voltage regulator and push-pull output; no external pull-up resistor is needed. For Raspberry Pi, use a voltage divider or logic level converter since GPIO is 3.3V.
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, it outputs a 5V digital signal that can be read directly by any Arduino digital pin without extra components.
Can it detect water through a plastic container?
Yes, it works through common plastics, glass, and ceramic up to 12mm thick. Ensure the container is non-metallic and the sensor is flush against the outer wall.
Does it work with metal tanks?
No, this sensor requires a non-metallic barrier or direct contact with the liquid. Metal containers block the capacitive field.
