12 eTape Liquid Level Sensor + extras
18 units available with a short lead time.
The eTape Liquid Level Sensor is a solid-state resistive sensor that measures fluid level without mechanical floats. 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.
The sensor is resistive, so it can be read directly from a microcontroller or Arduino ADC pin with a simple voltage divider circuit. A 4-pin connector and 560Ω resistor are included so you don't need to solder directly to the delicate sensor pins.
