Description

This is a great little water level detector sensor.  Use it for detecting rain or water levels in your home, garden, basement, hydroponics systems – where ever you need to measure water level, and, it’s Arduino compatible.

Specifications:

• Operating voltage: DC3-5V
• Operating current: less than 20mA
• Sensor Type: Analog
• Detection Area: 40 x 16mm
• Production process: FR4 double-sided HASL
• Operating temperature: 10-30 C
• Humidity: 10% -90% non-condensing
• Product Dimensions: 62 x 20 x 8mm

Example Code:

Connect the module with Arduino. Uploading the following code to Arduino:

void setup(){
Serial.begin(9600);
}
void loop(){
Serial.print("Water level Sensor Value:");
Serial.println(analogRead(A5));
delay(100);
}

Put the module in a glass of water and run. Open serial Monitor and you could read the value. Now as you add water to the glass, the value increases. Or you could add salt to the water, the value increases too.
