First Layer (Sensors and Actuators)

Sensors gather and accumulate relevant information from an object or the environment after

which it is converted into useful data. For example, consider how you can use gestures on your

phone by simply moving your phone in the air. Your phone detects the motion and converts

the observation into useful data. On the other hand, actuators can alter the physical state of an

object. For instance, it can modify the airflow of a valve or open/close a power supply.

Sensors and actuators can work with a wide range of applications. For instance, they can

work with robotic camera systems, air quality sensors, water-lev ...
