To be considered “intelligent,” a device must possess a variety of technologies and functions. Here are some of the most common intelligent technologies found in devices today:
Sensors: These components are used to detect and measure the device’s immediate environment, such as temperature, motion, light, and anything else the device needs to detect or measure. When certain conditions are met, the device will start or stop operating or report environmental conditions via an alarm. This is why the device seems almost magical, as it appears to act on its own without our prompting.
Actuators: These mechanisms can move or control peripheral devices or systems, such as automatically adjusting a thermostat or starting a motor or speaker. They receive signals from the smart device’s microcontroller and then apply the changes to other components within the smart device.
A microcontroller is a small, low-power computer (similar to an Arduino) that processes data from sensors and controls actuators or other components within the smart device.
Some smart devices contain more powerful processing units (like modern smartphones), allowing them to perform more computationally intensive tasks, such as video processing in a smart doorbell.
operating system
● Embedded operating systems are designed to perform specific tasks within larger mechanical or electrical systems.
● Real-time operating systems (RTOS) can process data and respond to events in real time, which is crucial for smart devices that must act within milliseconds.
● Linux-based operating systems are also widely used in smart devices due to their flexibility and open-source nature.
