1.3 How IOT works?
Just like, the internet has changed our way of communicating and interacting with each other by connecting us with the World Wide Web, Similarly IoT has aimed to connect different devices and therefore facilitate man to machine and machine to machine interactions.
Basically, IOT works with 4 fundamental components:
Sensors
Connectivity
Data Processing
User Interface
1.Sensors: A sensors is a device which help in collecting data from the surrounding environment. All of this collected data can have various degrees of complexities ranging from a simple temperature monitoring sensor or a complex camera module sensor.A device can have multiple sensors that can bundle together to do more than just sense things. For example, our phone is a device that has multiple sensors such as GPS, accelerometer, camera, etc.
2. Connectivity : Now, the collected data is sent to a cloud but it needs a medium for transport.The sensors can be connected to the cloud through various mediums of communication and transports such as cellular networks, satellite networks, WiFi, Bluetooth, wide-area networks (WAN), low power wide area network and many more.
3. Data Processing:After this, when the data is collected and sent to cloud, then the software perform the processing of the acquired data.For example: reading the temperature value from the temperature sensor, motion from motion sensor, etc.
4. User- Interface : Next, the information made available to the end-user in some way. This can achieve by triggering alarms on their phones or notifying through texts or emails.Also, they can install a interface through which they can check their IoT device such as camera installed in homes etc.
