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.

Easy integration
Plug and play with my ESP32. The digital output threshold is easy to set. Highly recommend for students.

Corroded after few months
Worked great initially but noticed some corrosion on the traces after constant exposure to water. Good for temporary projects.
Q: What is the response time?
A: The response is nearly instant, typically under 100 milliseconds.
Q: Can I extend the cable?
A: Yes, you can solder extension wires, but ensure proper insulation to prevent short circuits.
Q: Can this be fully submerged?
A: It is splash resistant and can handle partial submersion, but long-term full submersion may reduce lifespan.
Q: Does it work with 3.3V logic?
A: Yes, it operates comfortably within the 3.3V to 5V range.
Q: Is there a library available?
A: This is a hardware sensor, so no specific library is needed. Standard analog read functions work.
