Embedded Systems Communication
Definition
Embedded System
A computerised system designed to perform a specific set of tasks within a larger device, often with real-time control and limited user interaction.
Note
Embedded systems are often invisible to users, seamlessly operating in the background to control devices and processes.
Purpose and Role
- Embedded systems allow digital products to:
- Function independently without needing external control
- Improve efficiency, precision, and responsiveness
- Automate everyday tasks
- They are essential for enabling digital communication and coordination between devices in modern systems.
Example
- Smart appliances (e.g. washing machines) that adjust cycles based on load
- Wearables like fitness trackers that collect and transmit health data
- Car systems that manage engine control, airbags, or parking sensors
- Industrial robots with sensors and feedback loops
- Medical devices that monitor and respond to patient needs
Key Characteristics
- Real-time operation: Responds instantly to input
- Low power & cost: Designed for efficiency and compact use
- Single-task focus: Built to do one job very well
How Embedded Systems Communicate
- Bluetooth, Wi-Fi, or wired connections
- Sensor data sent to apps or cloud systems
- Instructions received from user interfaces or remote servers
Example
In a smart refrigerator, embedded systems monitor food inventory, adjust temperature settings, and send alerts to your smartphone when items are running low.
