Explanation

A Global Sensor Network is built for monitoring and collecting data from various sensors deployed across the globe. These sensors can measure a wide range of environmental parameters such as temperature, humidity, air quality, radiation levels, and more. The data collected by these sensors is typically used for scientific research, environmental monitoring, weather forecasting, disaster management, and various other applications aimed at understanding and managing the Earth's natural systems.
