What is the Internet of Things (IoT)?

  • Definition: IoT refers to a network of physical objects (“things”) embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet.
  • Examples: Smart thermostats, fitness trackers, connected refrigerators, smart irrigation systems, city traffic sensors.

Importance in Science

Data Collection and Analysis

  • Environmental Monitoring: IoT sensors collect real-time data on air quality, water purity, and climate conditions. This helps scientists track changes and predict environmental events.
  • Biological Research: Wearable IoT devices monitor animal movements, body temperature, and heart rates, providing valuable data for ecology and zoology.
  • Space Exploration: IoT-enabled sensors on satellites and rovers transmit data about planetary environments, enabling remote scientific analysis.

Experiment Automation

  • Smart Labs: IoT devices automate experiments, control lab conditions (temperature, humidity), and record measurements, reducing human error.
  • Remote Access: Scientists can operate equipment and gather data from anywhere, enabling global collaboration.
