microwave sensor ufo led high bay light

The generated microwave sensor ufo led high bay light can be easily realized on a preset basis. For the third and last layer (C3), a Wi-Fi/BLE bridge was added to enable people to control their lighting through the cloud within the BLE grid. This type of setting enables people to remotely confirm the lighting status or configuration settings at any time and any place, or set the most suitable configuration in a smart space. How does networking make smart phones the center of smart lighting?

The three layers mentioned above are becoming more and more common in lighting control for several reasons. The first reason is the evolution of the protocol, namely Bluetooth, which can now adapt to smart technology through Bluetooth Low Energy (BLE). BLE is completely different from ZigBee. ZigBee does not support the direct control of smartphones, but it is the center of many IoT activities today, especially at terminal nodes. However, BLE can support grid technology and can directly control IoT applications, which is very important for high-density terminal node applications such as smart homes.

Standardizations such as DALI, ZigBee, and Bluetooth are already in progress because they play an important role as the core connection method for lighting networks, sensor networks, and wireless telephone networks. Therefore, most of the upcoming solutions will be based on standardized hardware and firmware so that all participants in the digital lighting industry can participate in the development of viable end-to-end solutions.

By the second half of 2017, most new smart lighting products will be based on DALI 2.0, ZigBee 3.0 and Bluetooth 5.0. The second reason is that due to the improvement and popularization of mobile networks, the development from 2G to 3G and 4G and LTE. These improvements ensure that smartphones can be easily connected to the cloud, and users can control lighting in real time from any location. In terms of the security and flexibility of the use of information services,
