A standalone-like smart device that can remotely track the variation of air pollutants in a power-saving way is created; Metal–organic framework-derived hollow polyhedral ZnO was successfully synthesized, allowing the created smart device to be highly selective and to sensitively track the variation of NO concentration; A novel photoluminescence-enhanced Li-Fi telecommunication technique is proposed, offering the created smart device with the capability of long distance wireless communication.
Remote tracking the variation of air quality in an effective way will be highly helpful to decrease the health risk of human short- and long-term exposures to air pollution. However, high power consumption and poor sensing performance remain the concerned issues, thereby limiting the scale-up in deploying air quality tracking networks. Herein, we report a standalone-like smart device that can remotely track the variation of air pollutants in a power-saving way. Brevity, the created smart device demonstrated satisfactory selectivity (against six kinds of representative exhaust gases or air pollutants), desirable response magnitude (164–100 ppm), and acceptable response/recovery rate (52.0/50.5 s), as well as linear response relationship to NO. After aging for 2 weeks, the created device exhibited relatively stable sensing performance more than 3 months. Moreover, a photoluminescence-enhanced light fidelity (Li-Fi) telecommunication technique is proposed and the Li-Fi communication distance is significantly extended. Conclusively, our reported standalone-like smart device would sever as a powerful sensing platform to construct high-performance and low-power consumption air quality wireless sensor networks and to prevent air pollutant-induced diseases via a more effective and low-cost approach.

制造出一种类似独立式的智能设备，它能够以节能方式远程跟踪空气污染物的变化；成功合成了金属有机框架衍生的中空多面体ZnO，使该智能设备具有高选择性并能灵敏地跟踪NO浓度的变化；提出了一种新型光致发光增强的可见光通信（Li-Fi）技术，赋予该智能设备长距离无线通信能力。
以有效方式远程跟踪空气质量变化对于降低人类短期和长期暴露于空气污染中的健康风险非常有帮助。然而，高功耗和较差的传感性能仍然是令人关注的问题，从而限制了空气质量跟踪网络的大规模部署。在此，我们报道了一种类似独立式的智能设备，它能够以节能方式远程跟踪空气污染物的变化。简而言之，所制造的智能设备表现出令人满意的选择性（针对六种代表性废气或空气污染物）、理想的响应幅度（164–100 ppm）、可接受的响应/恢复速率（52.0/50.5 s）以及对NO的线性响应关系。经过2周的老化后，所制造的设备在3个多月的时间里表现出相对稳定的传感性能。此外，还提出了一种光致发光增强的可见光通信（Li-Fi）技术，并且显著扩展了Li-Fi通信距离。总之，我们报道的类似独立式的智能设备将作为一个强大的传感平台，以更有效和低成本的方式构建高性能、低功耗的空气质量无线传感器网络，并预防空气污染物引起的疾病。[图片：见正文]
