Introduction

Ever wondered how your smartwatch counts your steps, a smart TV guesses what you like to watch, or devices in your home hear your voice commands?

The answer lies in IoT, or the Internet of Things-one of the fastest-growing technologies of 2026.

Experts predict that by 2026, more than 75 billion devices will be connected through IoT, and embedded systems will form the backbone powering them.

IoT is no more a concept of the future. Already, it's transforming homes, industries, healthcare, and everyday life into smart automated and AI-enhanced devices.

What Is IoT: Internet of Things?

IoT stands for Internet of Things and is a network of everyday devices connected through the internet that can collect data, share it, and analyze it.

These devices contain:

Sensors

Microcontrollers (Embedded Systems)

Internet connectivity: WiFi, LTE, Bluetooth

Software or AI algorithms
Analogy:

Think of IoT as a network of "talking" devices.

Just like humans communicate and make decisions, IoT devices share information with each other and react automatically - without human effort.

What are Embedded Systems?

An embedded system is a small computer constructed inside a device, which governs certain functions.

Examples include:

Microcontrollers

Sensors

Motor controllers

Smart chips

These systems serve as the brain for IoT devices.

Importance of IoT + Embedded Systems

IoT combined with embedded systems shapes the future for several reasons:

1. Automation Everywhere

Devices can function on their own, turning lights on, adjusting air conditioner temperatures, or even monitoring your health.

2. Better Decision Making

IoT devices collect data and, utilizing the data collected, improve user experience, such as Netflix recommendations.

3. Time & Cost Efficiency

These smart devices save resources by optimizing energy use, reducing errors, and increasing productivity.

4. Practical Applications

Smart homes: Alexa, Google Home, smart bulbs

Wearables: smartwatches, fitness bands

Industry: Sensors in factories preventing machine failures

Healthcare: Remote patient monitoring

Transport: Smart parking, tracking systems

Automation is expected to cut operational costs by over 20% in IoT-enabled industries by 2026.

How It Works

Here's how IoT and Embedded Systems work, step by step:

Step 1: Data Collection

Sensors capture environmental changes, such as temperature, motion, and pressure.

Step 2: Data Processing

The data is analyzed locally by embedded systems/microcontrollers.

Step 3: Connectivity

Devices send data to apps or cloud servers through WiFi, LTE, Bluetooth, Zigbee, etc.

Step 4: Cloud + AI Processing

AI models analyze data and make predictions or automated decisions.

Step 5: Output Action

The device responds by sending alerts, changing settings, or triggering other devices.

Common Mistakes in IoT Development

Mistake 1: Poor Security

Many developers disregard device security.

Solution:

Encrypt data, use strong passwords, and securely transfer data.

Mistake 2: Overloading devices with heavy processing

IoT devices have limited memory.

Solution:

Keep code lightweight, leveraging the cloud for heavy tasks.

Mistake 3: Using the wrong communications protocol

Not all devices are designed to use WiFi or Bluetooth for long-range tasks.

Solution:

Select the appropriate protocol depending on the range and data needs: LoRa, Zigbee, NB-IoT, etc.
