Sensors are fundamental components in IoT and embedded systems, serving as the interface between the physical world and digital systems. These devices detect and measure changes in the environment, such as temperature, humidity, light, motion, and more. In IoT applications, sensors collect data from the surrounding environment, which is then processed and used for various purposes, such as monitoring, control, and automation.

In embedded systems, sensors play a crucial role in enabling devices to interact with the external world. For example, in a smart thermostat, sensors measure the room temperature and humidity, allowing the thermostat to adjust the heating or cooling accordingly.

Sensors are also essential for collecting data in industrial IoT applications, such as predictive maintenance in manufacturing. By monitoring the condition of machinery using sensors, companies can predict when maintenance is needed, reducing downtime and maintenance costs.

Understanding how sensors work and how to integrate them into IoT and embedded systems is essential for anyone interested in pursuing an Internet of Things course.
