12 Standard eTape Liquid Level Sensor with Plastic Casing
Discontinued
The Standard eTape Liquid Level Sensor with plastic casing is a solid-state resistive sensor that measures fluid level without mechanical floats. The hard plastic jacket makes this version more robust and less susceptible to physical damage than the bare-tape models.
As the liquid level rises, the hydrostatic pressure compresses the sensor envelope, decreasing its resistance. The output is inversely proportional to the liquid height — lower liquid means higher resistance, higher liquid means lower resistance. This version includes a 3-pin JST connector with power (red), ground (black), and analogue output (white) — simply connect to 3V or 5V and read the analogue voltage with any ADC or Arduino analogue pin.
