sensors and sensor networks

Sensors are devices that detect and measure specific physical properties, such as temperature, motion, light, or humidity, and convert them into signals for analysis. Sensor networks consist of multiple sensors connected via communication links, working together to monitor and collect data over larger areas or systems. They enable real-time observation and insights in applications like environmental monitoring, smart cities, and healthcare. By coordinating data from various sensors, sensor networks provide comprehensive, efficient, and automated ways to observe, analyze, and respond to changing conditions in diverse environments.
