 QR code and download this article càng được đề xuất trong nhiều lĩnh vực khác nhau, từ nhà thông minh, văn phòng thông minh đến
 nông nghiệp thông minh. Trong bài báo này, một nền tảng tổng quát cho các ứng dụng giám sát
 thông minh dựa trên mạng IoT được đề xuất. Trong nền tảng này, các nốt cảm biến năng lượng
 thấp được dựa trên nền tảng bo mạch micro:bit, có khả năng cung cấp nhiều kết nối với các cảm
 biến khác nhau. Khả năng giao tiếp không dây cung cấp một giải pháp hoàn chỉnh để triển khai
 hệ thống ở những nơi mà việc đi dây là không khả thi. Dữ liệu được thu thập không dây bởi một
 nốt trạm chủ, được cài đặt hệ điều hành Android Things do Google cung cấp. Cách tiếp cận của
 chúng tôi cung cấp một giải pháp triển khai với chi phí thấp với thiết lập tối thiểu, và đặc biệt có
 thể mở rộng được cho các ứng dụng giám sát. Để có thể hỗ trợ nhiều loại ứng dụng khác nhau với
 việc thay đổi là ít nhất, hệ thống của chúng tôi đễ dàng mở rộng với các cổng kết nối nối tiếp, như
 là cổng Truyền/Nhận bất đồng bộ thông dụng và cổng giao tiếp nối tiếp SPI. Với những cổng giao
 tiếp này, chỉ với một đường dữ liệu, nhiều loại cảm biến có thể được kết nối vào hệ thống. Trong
 bài báo này, hệ thống của chúng tôi được ứng dụng để theo dõi nước tự động trong nuôi trồng
 thủy sản dựa trên dữ liệu cảm biến oxy hòa tan, pH và nhiệt độ. Dữ liệu được tải lên điện toán đám
 mây cho việc giám sát từ xa và cung cấp những cảnh báo khi giá trị của cảm biến vượt ngưỡng an
 toàn.
