Basics of IoT and Sensor Technology

What is IoT?

The Internet of Things (IoT) refers to a network of physical devices—vehicles, machines, home appliances, and more—that are embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems over the internet. The primary components of IoT include:

1. Devices: Physical objects embedded with sensors and actuators.
2. Connectivity: Networks that facilitate communication between devices.
3. Data Processing: Systems that process and analyze data collected from devices.
4. User Interface: Platforms that allow users to interact with the IoT system.

What are Sensors?

Sensors are devices that detect and measure physical properties from the environment and convert them into signals that can be read by an observer or an instrument. Common types of sensors include:

1. Temperature Sensors: Measure temperature levels.
2. Humidity Sensors: Measure moisture levels in the air.
3. Proximity Sensors: Detect the presence or absence of objects.
4. Pressure Sensors: Measure the pressure of gases or liquids.
5. Light Sensors: Measure the intensity of light.
6. Motion Sensors: Detect movement or vibration.
7. GPS Sensors: Determine the geographic location of an object.
