Description: A flood sensor is a device designed to detect water levels in a specific area, aimed at preventing flooding and minimizing damage. These sensors are an integral part of Internet of Things (IoT) systems, as they allow real-time monitoring and data transmission over wireless networks. Flood sensors are typically equipped with detection technology that may include electrodes, floats, or pressure sensors, which measure water height and send alerts when predefined thresholds are exceeded. Their relevance lies in their ability to alert users about dangerous conditions, enabling quick and effective decision-making for emergency management. Additionally, these devices can be integrated with home automation or infrastructure management systems, providing a proactive solution for disaster prevention related to water. In a world where climate change and the increase of extreme weather events are becoming more common, flood sensors have become essential tools for property protection and public safety.
