IoT stands for Internet of Things. Connecting everyday things embedded with electronics, software, and sensors to the internet enables them to collect and exchange data.

Benefits of IoT:

  • Efficient resource utilization
  • Minimizing Human effort
  • Saves time
  • Development of AI through IoT
  • Improved security


IoT Features:

  • Connect various things to the IoT Platform
  • Analyze the data collected and use it to build business intelligence
  • Integrate various models to improve user experience.


IoT Ecosystem:

Basic architecture:

  • Application layer: Responsible for delivering application-specific services to the user. Defines an application in which the IoT can be deployed.
  • Network layer: Responsible for connecting smart things, network devices, and servers. Also used for transmitting and processing sensor data.
  • Perception layer: Sensors sense and gather information about the environment. Senses physical parameters or identifies other objects in the environment.


Application of IoT:

  • Energy conservation
  • Smart Transport
  • Social life and entertainment
  • Supply chain and logistics
  • Health and fitness
  • Smart environment
  • Home automation
  • Smart agriculture


IoT Sensor:

It is a device that captures real-world data and translates it into a piece of information that could be interpreted by other instruments. As the name suggests, sensors react to stimuli – be it changes in temperature, sound, or different properties. Hence a sensor in an IoT system senses the desired physical quantity and converts it into electrical signals transmitted to the central cloud-based server directly or via an on-site microcontroller.


Types of Sensors:

  • Temperature sensor
  • Humidity sensor
  • Proximity sensor
  • Level sensor
  • Gyroscope.


Features of Sensors:

  • Range
  • Accuracy
  • Sensitivity
  • Resolution
