Good accuracy for the price
I tested this against a calibrated gauge and it was within the specified tolerance. Great value for hobbyist projects involving liquid depth.

Solid performance
Works well for fresh water applications. I haven't tested it with chemicals, but for plain water level sensing, it is excellent.

Reliable and compact
Small form factor made it easy to integrate into my tight enclosure. No leaks after two weeks of continuous submersion testing.

Perfect for my aquarium project
This sensor works flawlessly for monitoring water levels in my custom aquarium setup. The analog output is stable and easy to read with an Arduino.

Easy to interface
Documentation could be better, but the pinout is standard. Got it working with a Raspberry Pi ADC in under an hour.

Great for student projects
We bought ten of these for our robotics competition. All units performed consistently. Highly recommended for educational use.
Q: Can I use this for measuring fuel levels?
A: This sensor is optimized for water and non-corrosive liquids. We cannot guarantee compatibility or safety with flammable fuels or aggressive solvents.
Q: Does this module come with waterproof cabling?
A: The module itself is designed for contact with liquids, but the header pins are not waterproof. You should apply conformal coating or use a waterproof enclosure for the connections.
Q: Is a separate library required for Arduino?
A: No specific library is needed. Since it outputs an analog voltage, you can simply use the standard analogRead() function in the Arduino IDE.
Q: Can this sensor measure saltwater levels?
A: While it can physically measure saltwater, prolonged exposure may cause corrosion on non-stainless parts. We recommend rinsing with fresh water after use or using a protective barrier for long-term marine applications.
Q: What is the maximum depth this 40kPa sensor can measure?
A: 40 kPa corresponds to approximately 4 meters (about 13 feet) of water column depth. Please ensure your application does not exceed this pressure limit.
