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.
5 FAQ
Q: Is the PCB module itself waterproof?
A: The probe is water-resistant, but the PCB module should be kept dry to prevent damage.
Q: What is the maximum water depth it can measure?
A: It detects presence rather than precise depth measurement. It works when water bridges the lines.
Q: Can I use this with 3.3V logic boards?
A: Yes, it operates comfortably between 3.3V and 5V DC.
Q: Do you provide sample code for this sensor?
A: Yes, please check the product description page for Arduino examples and wiring diagrams.
Q: How long is the included cable?
A: The standard cable length included in the package is 1.5 meters.
