It does away with clunky mechanical floats, and easily interfaces with electronic control systems. \u003cstrong\u003eWhat separates this from our other eTape Liquid Sensor is the hard plastic jacket that makes it less susceptible to damage.\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThis is a very unique sensor, we haven't seen anything else that is affordable and accurate for measuring liquid level. This particular sensor is the 12\" model. It comes with a 3-pin JST connector for power and ground in and analog out\u003cbr\u003e\u003cbr\u003eSince 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\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eNote\u003c\/strong\u003e: This product only comes with the plastic enclosed eTape Liquid Level Sensor.  In our demo, we set it up with an Adafruit Metro, a TB6612 Stepper Motor Driver Breakout Board, and an Automotive Gauge Stepper Motor.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e\u003ch2\u003eTechnical Details\u003c\/h2\u003e\u003cdiv id=\"tab-technical-details-content\" class=\"panel-collapse collapse in\"\u003e \u003cdiv class=\"row\"\u003e \u003cdiv class=\"col-lg-12 col-md-12 col-sm-12 col-xs-12\"\u003e\n\u003cp\u003eDimensions:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e305mm x 29mm x 13mm \/ 12\" x 1.14\" x 0.51\"\u003c\/li\u003e\n\u003cli\u003eWeight: 56g\u003c\/li\u003e\n\u003cli\u003eSensor Output: 400-2000Ω ±20%\u003c\/li\u003e\n\u003cli\u003eRef.
