To realize real-time online detection of heavy metal pollution in aquatic environment, a new type of remote monitoring system was designed. The System mainly consisted of monitoring terminal, gateway, GPRS network and PC control center software. First, the concentration of heavy metal ions was detected by monitoring terminal through ion selective electrode array and the automatic compensation method...
In recent years, security risks of equipment are very prominent. In order to ensure normal operations, equipment inspection is required to standardization. Information technology is an important means of ensuring the safe operation of equipment. In this paper, a new equipment inspection system based on Zigbee is presented. This system is composed of data management center, wireless gateway, wireless...
The degradation process in pentacene-based organic thin-film transistors (OTFTs) is investigated. Pentacene-based OTFTs were fabricated with and without octadecyl trichlorosilane (OTS) treatment, and their device characteristics during lifetime test are evaluated using low-frequency-noise (LFN) spectroscopy. It is found that the devices exhibited the 1/f type of noise behavior with generation and...
