Four Components of IoT
The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
A complete IoT system integrates four distinct components:
- Sensors/Devices:
Sensors/Devices collect data from their environment. e.g. Our phone is a device that has multiple sensors like GPS, camera, Motion etc. where data is being collected based on surroundings
2. Connectivity to Cloud :
The sensors/devices can be connected to the cloud and store, through a variety of methods including: Bluetooth, WiFi, Cellular etc.
3. Data Processing :
Software perform data processing on cloud data to get a analyzed or computed data. e.g Computing the temperature within an acceptable range.
4. User Interface :
.
The analyzed or computed data is made useful to the end user via and alert(email, text, notification). e.g a alert message when temperature is beyond the acceptable range.
