Working Principle
The Y26 sensor leverages the capacitance properties of water to detect liquid levels. When no liquid is near the sensor, it registers minimal static capacitance. As liquid approaches, its parasitic capacitance increases the total capacitance value, which is then processed by the control IC. This signal change is analyzed using a predefined algorithm, and when it exceeds the threshold, the sensor outputs a signal indicating that the liquid level has been detected.
The Y26 sensor’s innovative design and robust performance make it an ideal solution for precise liquid level monitoring across a wide range of applications.
