Study Notes

Real-Time Location Systems (RTLS)

Types of RTLS: Precision-based and Proximity-based.
Precision-based RTLS provides accurate location tracking (over 300 meters) using technologies like Ultra-Wideband (UWB).
Proximity-based RTLS tracks within a zone (a few square feet), utilizing cheaper technologies such as BLE Bluetooth beacons and Wi-Fi, with a range up to 20 meters.
Applications include tracking medical equipment, staff location, and asset management.

GPS Tracking Software

Utilizes Internet of Things (IoT) and Global Positioning System (GPS) to track locations in real-time.
Gathers data from GPS sensors on objects or individuals and sends it to a central server for processing and visualization.
Common applications include logistics, fleet management, crime detection, and personal safety.
GPS receivers capture signals from GPS satellites, still a reliable solution for payment systems.

IoT Encryption Algorithms

RSA Algorithm is a widely used asymmetric encryption method ensuring secure message transmission without sharing the code.
Key lengths range from 768-bit to over 4096-bit, ensuring secure communication and data integrity.
TLS/SSL handshake process involves client and server exchanging messages for secure communication, including key verification and session key generation.

Embedded Systems

An embedded system consists of hardware and software designed for specific functions, often using sensors to automate actions.
They are used in everyday devices like TV remote controls, microwave ovens, and gaming consoles.

Microprocessor vs. Microcontroller

Microprocessors: Central unit of a computer, external memory and I/O connections leading to larger circuit sizes, higher costs, and power consumption.
Microcontrollers: Heart of embedded systems, integrating memory, CPU, and I/O, resulting in smaller circuits, lower costs, and reduced power consumption.

Embedded System Hardware Components

Sensor: Measures physical quantities and converts them to electrical signals.
A-D Converter: Converts analog signals from sensors to digital format.
Memory: Storage space for device data.
Bus: Transfers data between components.
D-A Converter: Converts digital data back to analog.
Actuator: Compares output and maintains approved levels.
Stop and Parity Bits: Manage data transmission verification and integrity.

UART Communication

Transmitting UART receives data parallelly and adds start, parity, and stop bits to the data frame.
Data is sent serially to the receiving UART, which discards extra bits and reads the packet bit by bit, transferring it in parallel for processing.

Applications of Embedded Systems in IoT

Smart Home: Home automation and enhanced security through connected devices.
Smart Cities: Implementing smart surveillance, traffic systems, and pollution monitoring.
Healthcare: Used in medical monitoring tools, enhancing patient care.
Automotive: Technologies include anti-lock braking, climate control, and emission monitoring.
Manufacturing: Emphasis on online operations and remote monitoring.
