A Water leakage sensor, also known as water sensor, is a device designed to detect the presence of water or moisture in a specific area.

These sensors are commonly used in homes, businesses, and industrial settings to prevent water damage and provide an early warning in case of leaks or flooding.

When water is detected, the sensor triggers an alert to notify the user of the potential leak. Alerts can be in the form of a loud alarm, notifications to a mobile device, or integration with a home automation system.

Many modern water leakage sensors are designed to integrate with smart home systems. This allows users to receive notifications on their smartphones or tablets and take immediate action, even if they are not at home.
