据预测，到 2020 年，物联网 (IoT) 设备的数量将超过 280 亿。由于传统射频频谱的短缺，使用可见光通信 (VLC) 进行物联网前景广阔。物联网网络可能只需要非常低的数据速率通信来传输传感或身份信息。在现有计算机通信标准和接口上实施 VLC 链路非常重要。在这些标准中，通用异步接收器/发送器（UART）非常流行。我们提出并演示了 VLC-over-UART 系统。执行误码率分析。讨论了所提出的 VLC-over-UART 系统中使用的不同组件和模块。然后，我们还使用所提出的 VLC 链路演示了实时同步温度、湿度和照度监控。
It is predicted that the number of internet-of-things (IoT) devices will be >28 billion in 2020. Due to the shortage of the conventional radio-frequency spectrum, using visible light communication (VLC) for IoT can be promising. IoT networks may only require very low-data rate communication for transmitting sensing or identity information. The implementation of a VLC link on existing computer communication standards and interfaces is important. Among the standards, universal asynchronous receiver/transmitter (UART) is very popular. We propose and demonstrate a VLC-over-UART system. Bit error rate analysis is performed. Different components and modules used in the proposed VLC-over-UART system are discussed. Then, we also demonstrate a real-time simultaneous temperature, humidity, and illuminance monitoring using the proposed VLC link.
