Study Notes
IoT Building Blocks
- IoT integrates multiple technologies to form a cohesive system comprising Smart Things, IoT Gateway, IoT Cloud, IoT Analytics, and IoT Applications.
Smart Things
- Smart things can be any object, either manufactured or retrofitted with electronic tags/sensors, capable of data exchange.
- Known as smart devices, they bridge the physical and digital realms.
- They feature unique digital identities, sensing capabilities, embedded processors, communicators, and actuators.
Sensor Functions
- Sensors are critical for smart things, enabling perception of environmental changes (e.g., temperature, pressure, humidity).
- They convert physical stimuli into electrical signals, which are essential for monitoring conditions.
Actuators
- Actuators perform actions based on sensor data, requiring energy and a control signal to function.
- After processing sensor information, commands are sent to actuators to execute decisions.
- Various types of actuators include electric-based, magnetic-based, mechanical-based, and hydraulic actuators.
Microcontrollers (MCUs)
- MCUs enhance the intelligence of smart devices and include processors, memory, and programmable input/output peripherals in a single chip.
- They differ from microprocessors found in PCs and are tailored for embedded applications, promoting cost-effectiveness.
- Key features of MCUs:
- Specific amount of RAM for processing.
- Flash memory for offline data storage.
- Multiple input/output pins for connecting sensors and actuators.
- Ethernet/Wi-Fi ports for Internet connectivity.
- Varying bit options affecting computation speed.
- Power supply pins for sensors.
Packet Tracer
- Packet Tracer is a versatile, cross-platform simulation tool developed by Cisco Systems for networking education.
- It utilizes a drag-and-drop interface for adding/removing devices, including IoT components.
- Supports programming in JavaScript, Python, and Blockly for simulations, aimed at simplifying understanding of networking concepts.
