🛠️ What is IoT? A Simple Analogy

Imagine your smart home as an orchestra. Each device—lights, thermostat, security camera—is a musician (a sensor) playing its part. The conductor (an IoT platform) ensures they work in harmony, while the sheet music (the connectivity, like Wi-Fi or Bluetooth) keeps them in sync. Together, they create a symphony of automation, making your home smarter! IoT connects devices to collect data, communicate, and act intelligently.

• Sensors: Devices that collect data (e.g., temperature sensors, motion detectors).
• Connectivity: Networks like Wi-Fi, Bluetooth, or Zigbee that let devices talk to each other.
• IoT Platforms: Software like AWS IoT or Google Cloud IoT that manage and process data.

2. Healthcare: Wearable devices like Fitbit track heart rate and send data to doctors for real-time health monitoring.
3. Smart Cities: IoT-enabled traffic lights reduce congestion by analyzing real-time traffic data (e.g., Singapore’s smart traffic system).

🔧 Project: Build a Temperature Monitoring System

Create a simple IoT system using a Raspberry Pi and a temperature sensor (e.g., DHT11) to monitor room temperature and display it on a web dashboard or phone app.

• Components: Raspberry Pi, DHT11 sensor, jumper wires.
• Steps:
  1. Connect the DHT11 sensor to your Raspberry Pi (follow Random Nerd Tutorials).
  2. Install Raspberry Pi OS and Python libraries (Adafruit_DHT).
  3. Write a Python script to read temperature data and send it to a free IoT platform like Blynk.
  4. Visualize data on a web dashboard or mobile app.
• Optional: Add alerts for high/low temperatures.

✅ Project Checklist

• ☑ Sensor is correctly wired to Raspberry Pi.
