Reliable analog output

I used this for a tank monitoring project. The analog values change smoothly with water depth. Great for calibration.

Good value but cable is short

The sensor itself is accurate for detecting water levels in my plant pot. I wish the connecting cable was a bit longer for my setup.

Perfect for my rain alarm

Works exactly as described. Easy to hook up to my Arduino Uno. Sensitivity is adjustable via the potentiometer.

Corroded after few months

Worked great initially but noticed some corrosion on the traces after constant exposure to water. Good for temporary projects.
