The intelligent lighting control system is one of typical applications of the Internet of things. The method of intelligent lighting control system based on industrial wireless technology is proposed in the paper. It used proposed three-point-control technology, and adjusting the brightness of lamps, turn on/off the lamps and a part of fault detection can be realized. At the same time, it can greatly reduce the cost of system. It will be useful to engineer and researchers.

Rapid Reaction

An efficient, sensitive, and low-cost method has been developed for turn-on fluorescence sensing of dopamine (DA). The method relies on the rapid reaction of DA and 3-Hydroxyphenylboronic acid (3-HPBA) via specific recognition between boronic acids and cis-diol of DA in alkaline solution. The reaction product shows an excitation wavelength of 417 nm and the maximum emission peak at 470 nm. The proposed method allows the determination of DA in the range of 50 nM–25 μM, and the whole detection can be completed within 5 minutes. Furthermore, the presented approach has good selectivity and has been successfully applied to DA sensing in human serum samples, showing great potential in clinical diagnosis.
