What is the primary role of sensors in IoT?

Sensors in IoT act as the input that observes the physical world and converts those observations into data the system can use. Their primary role is to collect data from the physical world, measuring things like temperature, humidity, motion, or light and turning those readings into electrical or digital signals. They don’t store data, route messages, or power devices—data storage is handled by memory or cloud services, networked components handle message routing, and power comes from a separate source. The value of sensors is that they provide the real-world measurements that enable monitoring, analysis, and automated responses.
