Arduino compatible
Easy to wire up using standard jumper cables. I used it for a plant watering system and it triggers reliably when the soil is wet.

Perfect for my rain alarm project
Works exactly as described. I connected it to my Arduino Uno and it detected water droplets instantly. Great sensitivity for the price.

Corrodes eventually
Functioned well for about a month of continuous exposure to water. The traces started to corrode after that. Good for temporary prototypes.

Great for prototypes
Fast delivery and the module is compact. I use it to detect leaks under my sink prototype. Very sensitive to moisture.

Good value but needs calibration
The sensor works well, but you need to adjust the potentiometer on the back to get the digital output right. Analog reading is stable.
Q: Is the sensor waterproof for long term submersion?
A: The PCB traces are exposed. While it detects water well, prolonged submersion may lead to corrosion over time. It is best for intermittent detection.
Q: Can it measure exact water depth in centimeters?
A: It provides an analog value corresponding to conductivity. You can calibrate it for relative depth, but it is not a precise ultrasonic depth meter.
Q: What is the length of the included cable?
A: The included Dupont connector cable is approximately 15cm in length, suitable for most breadboard setups.
Q: Do I need to install a specific library for this?
A: No specific library is required. You can use standard analogRead() functions in the Arduino IDE to read the sensor values.
Q: Does this work with 3.3V logic boards like ESP32?
A: Yes, the module operates within the 3.3V to 5V range, so it is fully compatible with ESP32 and similar boards.
