This eTape Liquid Level Sensor is a solid-state sensor with a resistive output that varies with the level of the fluid. It does away with clunky mechanical floats, and easily interfaces with electronic control systems. What differentiates this from our other eTape Liquid Sensors is the hard plastic jacket that makes it less susceptible to damage.

The eTape sensor's envelope is compressed by the hydrostatic pressure of the fluid in which it is immersed. This results in a change in resistance that corresponds to the distance from the top of the sensor to the surface of the fluid. The sensor's resistive output is inversely proportional to the height of the liquid: the lower the liquid level, the higher the output resistance; the higher the liquid level, the lower the output resistance.

This is a very unique sensor, and we haven't seen anything else that is affordable and accurate for measuring liquid level. This particular sensor is the 5" version, and it comes with a 3-pin JST connector.

Since the sensor is a resistive divider / analog out, it is easy to read it using a microcontroller/Arduino ADC pin. Connect the red wire to 3 or 5V power, the black wire to ground, then read the analog divider output on white

Please Note: This product only comes with the 5" plastic enclosed eTape Liquid Level Sensor.  In our demo, we set up a 12" enclosed version with an Adafruit Metro, a TB6612 Stepper Motor Driver Breakout Board, and an Automotive Gauge Stepper Motor to demonstrate functionality.
