Components of IoT

Sensors: Sensors help in collecting very minute data from the surrounding environment.
Devices: A device can have multiple sensors that can bundle together to do more than just sense things.
Connectivity: The sensors can be connected to the cloud through various mediums of communication and transports such as cellular networks, satellite networks, Wi-Fi, Bluetooth, wide-area networks (WAN), low power wide area network and many more.
Data Processing: Once the data is collected and it gets to the cloud, the software performs processing on the acquired data.
User Interface: 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.
