Easy to wire

Clear labeling on the pins. 3.3V logic works fine with ESP8266 without level shifters.

Good value sensor

Does the job well for basic level detection. Cable could be a bit longer for my specific tank setup.

Great for Arduino projects

Worked perfectly out of the box. Very sensitive to water droplets and easy to integrate with my UNO board.

Reliable depth detection

Using this for my rain gauge project. No false positives so far even with varying humidity.
