Arduino Water Level Sensor Module – Liquid Depth & Rain Detection Sensor for IoT Projects in Pakistan

Overview 

The Water Level Sensor is an easy-to-use, cost-effective tool for measuring the presence and depth of water. It features a series of traces that act as a variable resistor. When the sensor is dipped into water, the conductivity between the traces changes based on the submerged area. This change is converted into an analog signal that your Arduino can read to determine if a tank is empty, half-full, or overflowing.

Key Features 

• Plug-and-Play Simplicity: No complex calibration needed—just power it up and read the analog pin.

• Compact & Low Power: Draws very little current, making it ideal for battery-operated IoT nodes.

• Corrosion Resistant: Designed with high-quality traces to withstand moisture, though it is best used for intermittent readings.

• Versatile Use: Can be used as a depth gauge for tanks or a “leak detector” placed on a floor.
