Adafruit 12" eTape Liquid Level Sensor + extras

The eTape Liquid Level Sensor provides an innovative solution for liquid level measurement with its solid-state design and resistive output. Unlike traditional mechanical floats, this sensor seamlessly integrates with electronic control systems to deliver precise readings.

The sensor features an envelope that is compressed by the fluid's hydrostatic pressure, altering its resistance based on the fluid level. This resistive output inversely corresponds to the liquid height: as the level decreases, resistance rises, and vice versa.

Ideal for applications such as hydroponics, aquariums, fountains, or even rain measurement, the 12-inch model offers versatility in monitoring systems. The package includes a 4-pin connector and a 560-ohm resistor for hassle-free installation, eliminating the need to solder directly to the sensor's pins. Easily connect it to a microcontroller or Arduino ADC pin to start collecting data efficiently.
