The 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. The eTape sensor#39;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#39;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, we haven#39;t seen anything else that is affordable and accurate for measuring liquid level. This sensor seems like it would be a handy addition to an hydroponics, aquarium, fountain or pool controller, or perhaps measuring a rain tube. This particular sensor is the 12 model, we also include a 4-pin connector and 560 ohm resistor. The connector is so you don#39;t have to solder directly to the delicate pins: instead, just solder to the connector and plug it onto the sensor.
Since the sensor is resistive, it is easy to read it using a microcontroller/Arduino ADC pin. Check the tutorials tab for a quick-start pointer.
