IoT – Internet of Things hay Internet vạn vật là những thuật ngữ không còn quá xa lạ. Trong những năm gần đây, thế giới công nghệ đã trở nên bùng nổ nhờ IoT. Nhưng để hiểu được IoT và việc ứng dụng vào thực tế vẫn còn nhiều hạn chế. Vì vậy, hãy cùng Cyberlife tìm hiểu rõ hơn về IoT.

1. Internet of Things là gì?

Internet of Things hay Internet vạn vật (IoT) là sự kết nối của các thiết bị với internet. Và các thiết bị kết nối với nhau thông qua các cảm biến. Nhờ IoT, các thiết bị trở nên thông minh hơn. Chúng có khả năng nhận và gửi thông tin, tự động hoạt động dựa trên các thông tin đã thu thập.

2. Sự phát triển không ngừng của IoT

Thuật ngữ “Internet of Things” xuất hiện lần đầu tiên vào năm 1999. Trải qua hơn 20 năm hình thành và phát triển, IoT đã phát triển không ngừng nghỉ và được ứng dụng trong rất nhiều lĩnh vực.

Vào năm 2021, có hơn 10 tỷ thiết bị IoT trên thế giới. Đến năm 2025, IDC dự kiến ​​lượng dữ liệu toàn cầu sẽ vượt quá 73 zettabyte – tương đương 73 nghìn tỷ gigabyte. Dù chúng ta không thể thực sự định lượng dữ liệu kỹ thuật số theo mặt vật lý.  Nhưng hãy tưởng tượng rằng nếu tất cả dữ liệu đó được chuyển đổi thành đĩa mềm như những năm 1990 rồi sắp xếp số đĩa đó thành 1 đường thẳng thì nó sẽ dài gấp 5000 lần khoảng cách từ Trái Đất lên Mặt Trăng.

Để IoT phát triển, một bộ công nghệ cụ thể phải kết hợp với nhau và phát triển đồng thời. Bao gồm: Khả năng kết nối, công nghệ cảm biến, big data, AI và điện toán đám mây…

3. Cách hoạt động của IoT

Các thiết bị IoT sẽ là tai mắt của chúng ta khi chúng ta không ở đó. Chúng thu thập bất kỳ dữ liệu nào đã được lập trình sẵn để thu thập. Có bốn giai đoạn chính trong quá trình này:

Cách hoạt động của IoT
Cách hoạt động của IoT

Chụp dữ liệu: Thông qua các cảm biến, các thiết bị IoT thu thập dữ liệu từ môi trường xung quanh. IoT có thể thực hiện thu thập các dữ liệu đơn giản như nhiệt độ hoặc phức tạp như thoái quen của người dùng

Chia sẻ dữ liệu: Sử dụng các kết nối mạng có sẵn, các thiết bị IoT gửi dữ liệu này đến hệ thống đám mây, đến một thiết bị khác  hoặc lưu trữ cục bộ theo hướng dẫn để xử lý.

Xử lý dữ liệu: Phần mềm được lập trình để làm điều gì đó dựa trên dữ liệu có sẵn. Chẳng hạn như bật quạt hoặc gửi cảnh báo.

Hoạt động dựa trên dữ liệu: Dữ liệu tích lũy từ tất cả các thiết bị trong mạng IoT được phân tích. Từ đó để các thiết bị ghi nhớ và hoạt động theo thói quen của người dùng.

4. Ứng dụng của Internet of Things (IoT) trong lĩnh vực nhà thông minh

Theo New York Times, 2022 là năm của xe điện, Metaverse và nhà thông minh. Đặc biệt sau làn sóng Covid 2 năm vừa qua, 70% người Mỹ trưởng thành khi được khảo sát năm 2020 cho biết đã cải thiện ngôi nhà của mình.

Các số liệu khác từ Statista chỉ ra, số lượng nhà thông minh trên toàn thế giới 2021 là 258,54 triệu nhà. Tỷ lệ sử dụng nhà thông minh là 12,2%. Có thể thấy ứng dụng IoT trong nhà thông minh đang là ứng dụng phổ biến nhất.

Nhiều người đã quen thuộc với mạng IoT trong chính ngôi nhà của họ. Thiết bị trong nhà giao tiếp với nhau thông qua các giao thức như Z-Wave hoặc Zigbee. Hệ thống tự động giám sát và hỗ trợ người dùng điều chỉnh ánh sáng, nhiệt độ, hệ thống an ninh… từ xa thông qua smart phone. Nếu bạn quên tắt đèn hoặc điều hòa trước khi ra khỏi nhà, thì đừng quá lo lắng. Bạn có thể yên tâm bật/tắt các thiết bị từ xa bằng điện thoại của mình.

IoT là một trong 35 nền tảng đã được Bộ Thông tin và Truyền thông thúc đẩy. Từ đó tạo ra nền tảng do doanh nghiệp Việt Nam làm chủ. IoT không chỉ mang lại giá trị cho người Việt, tổ chức, cơ quan nhà nước mà còn hướng ra thế giới. Trong tương lai, IoT được nhận định sẽ bao phủ nhiều lĩnh vực hơn nữa, trở thành làn sóng thay đổi cuộc sống của mỗi người.
