Adafruit 5" eTape Liquid Level Sensor with Plastic Casing

The eTape Liquid Level Sensor is a solid-state sensor designed with a resistive output that automatically adjusts based on fluid level, eliminating the need for clunky mechanical floats.

This model features a robust hard plastic jacket for enhanced durability. As the sensor is submerged, hydrostatic pressure compresses its envelope, altering resistance and providing an accurate measurement of fluid level.

With a resistive output inversely proportional to the liquid height, it interfaces seamlessly with electronic systems using a simple 3-pin JST connector. It's compatible with microcontroller/Arduino ADC pins for easy readings.

Specifications include a 5-inch size and connections for both 3V or 5V power. Suited for precise liquid measurements, this sensor is distinctive in its affordability and reliability.
