What’s the Role of IoT in Smart Water Management?
IoT, or the Internet of Things, refers to a network of seamlessly interconnected devices that share data. Ultimately, the efficiency of any smart water technology depends on how well different parts of the system can work together. IoT acts as the essential link connecting these parts and enabling communication. Let’s delve into how the process works.
Specialized sensors collect important data ranging from water quality, pressure, temperature, water flow rates, etc. IoT devices then transmit this data in real-time to central monitoring systems. Central monitoring systems analyze real-time data and enable rapid responses to changes in various parameters.
IoT devices are usually linked to computer software with machine-learning capabilities. Machine learning algorithms enable computer systems to learn from patterns and get better at making smarter decisions. Machine learning is especially important where big data is involved. Big data results from collecting vast and diverse sets of information, for example, from multiple smart water systems in a region.
Machine learning conducts predictive analysis, anticipates future issues, and initiates corrective measures. This proactive approach goes a long way toward preventing waste or damage to water distribution systems. In the long run, the whole IoT-based system guarantees maximum efficiency.
