Study Notes

Actuators and Their Role in IoT

Actuators are essential components that take actions based on sensor readings, leading to system responses.
Their operation necessitates two primary requirements: energy and a control signal.
In IoT systems, commands are transmitted from a control center to actuators after processing sensor data.

Types of Actuators

Actuators can be classified into several categories:
- Electric-based actuators
- Magnetic-based actuators
- Mechanical-based actuators
- Hydraulic actuators

Microcontrollers (MCUs)

MCUs serve as controllers that enhance the intelligence of IoT applications beyond simple sensors.
They are built with one or more processors, memory, and programmable input/output peripherals on a single chip.
Distinguished from microprocessors used in PCs, MCUs are specifically designed for embedded applications.

Features of MCUs

Equipped with a defined amount of RAM for temporary data storage.
Include flash memory for offline data storage.
Offer a range of input/output pins (1 to 100+) for sensor and actuator integration.
Feature Ethernet/Wi-Fi ports to facilitate Internet connectivity.
Available in various bit architectures, influencing computational speed.
Have power supply pins dedicated to powering attached sensors.

Packet Tracer Tool

Packet Tracer is a visual cross-platform tool developed by Cisco Systems for understanding computer networking concepts through simulations.
Compatible with multiple operating systems: Linux, Windows, Android, and macOS.
Utilizes a simple drag-and-drop method for adding or removing various network devices, including IoT devices.
Supports programming in several languages, such as JavaScript, Python, and Blockly, simplifying the simulation process.
