A Wireless Sensor Network (WSN) is a collection of spatially distributed sensors that monitor and collect data about environmental conditions, such as temperature, humidity, and light. These sensors communicate wirelessly, allowing them to transmit information to a central system for analysis. WSNs are commonly used in applications like environmental monitoring, smart cities, and industrial automation. The main components of a WSN include the sensors, a communication network, and a data processing unit. The sensors gather data and send it to a central server or cloud platform, where it can be processed and analyzed. This technology enables real-time monitoring and decision-making, improving efficiency and responsiveness in various fields.
