IoT-Based Water Leak Detection Systems

Introduction

Water leaks are a major concern for homeowners, businesses, and municipalities. Undetected leaks can lead to property damage, mold growth, and significant water wastage, increasing utility costs and environmental impact. Traditional leak detection methods are often inefficient, manual, and reactive, leading to costly repairs and wastage.

With the Internet of Things (IoT), water leak detection has transformed into a smart, automated, and real-time process. IoT-based water leak detection systems leverage sensors, connectivity, cloud computing, and artificial intelligence (AI) to detect, analyze, and alert users to leaks instantly, preventing major damage.
