The Bluetooth technology is a short range wireless technology, and it’s the piconet network. The Bluetooth technology is defined and maintained by the Bluetooth Special Interest Group (SIG). The newest Bluetooth technology is Bluetooth 4.0, and it also calls Bluetooth low energy (LE). The Bluetooth LE has the following features like worldwide operation, robust, short range, low power and built-in most of mobile devices.

Wireless Locating System can be used in indoor and outdoor environments. It can monitor the exact location of certain objects or personsand integrate the location information into the back-end servers. In addition, it combines the emergency applications and makes those who call help can be found immediately. And then, the WLS becomes a safety-based locating system. The WLS can be used in industrial or commercial applications, such as: the large commercial offices, the shopping malls, the high-voltage electrical room, the toxic gas room, the ultra-high temperature processing factories, the hospitals or care centers and etc. The customers in the shopping mall probably are changing consumer behavior. Does the store supervisor grasp your opportunity yet? Maybe there are unscrupulous visitors to stroll inside offices or wrongdoing, do you find it? Someone is in danger and calling help in the hazardous working area, do you feel that? Patients who stay in the bathroom or toilet has exceeded the normal time, do you find the situation? These problems are difficult to detect and may cause harm to people or to the enterprise. The WLS could helpto find out the problems and provide the efficient way to manage them. (More...)

LoRa, coined from “Long Range”, is a proprietary spread spectrum modulation developed by Semtech for low power, low data rate and long range wireless communication. It’s an alternative to other modulations such as PSK and FSK and is tailored for the unique requirements needed by the Internet of Things(IoT). LoRa wireless products are the ultimate solution for eliminating repeaters, reducing cost, extending battery life and improving network capacity.

In response to the Internet of Things, big data analysis, industry 4.0, energy-saving and carbon-reduction requirements, ICPDAS has developed the "Industrial Wireless Sensor Network" solution. In addition to integrating current, temperature measurement and wireless transmission functions into one module, the ultra-low power consumption can be matched with a current comparator (hereinafter refer to CT) for inductive charging, it can meet the supply and demand balance of working power and achieve continuous uninterrupted measurement equipment parameters with sufficient power. The setting can be completed by dip switch, which not only doesn't affect the production process, but also greatly saves system construction time and reduces maintenance costs. To meet the needs of monitoring equipment power consumption, predictive maintenance and power panel temperature monitoring, it's helpful to maintain the production line equipment and avoid accidents caused by aging of power panel equipment and cables.
