Data acquisition has played a key role in the IoT era, with increasingly more devices being interconnected and wireless applications becoming the preferred network solution. Now, Advantech has combined the three core functions of data acquisition, processing and publishing into a single input/output (I/O) module to meet the needs of a wide range of industries, such as environmental monitoring, machine monitoring and smart cities.
With its WISE-4000 series, Advantech provides complete, modularized and ready-to-use wireless sensing solutions for IoT application. The wireless sensor nodes do not need to go through a gateway to provide information, which makes deployment much easier. As an almost limitless number of I/O modules, WISE-4000 can gather the information from any third-party sensors and connect to an existing network.
As well as various I/O types, the WISE-4000 series provides data pre-scaling, data logic and data logger functions. The WISE-4000’s data logger sends time-stamped information to a Dropbox or Microsoft Azure account or a private cloud depending on the configuration, and it can buffer the devices’ data so that in the event of network failure, no data is lost before it is sent to the administrator. This data is accessible via mobile devices and can be securely published to the cloud – any time and anywhere.
The WISE-4000 series leverages Wi-Fi, cellular and low-power wide-area networks (LPWANs) such as LoRa, NB-IoT/eMTC, and proprietary LPWAN, to meet specific wireless communication requirements. The sensor nodes incorporate three security steps to ensure safety for IoT data.
Wi-Fi WPA2 encryption: All the data via Wi-Fi will be encrypted during transmission.
HTTPS secure socket: The protocol for transmitting data, which prevents eavesdropping and tampering.
User authorized: The user needs to login to the webpage before configuration; the white list can be set in web configuration to prevent unauthorized IP addresses.
Since the WISE-4000 uses the popular representation state transfer (REST) API, the modules seamlessly integrate with IT systems and reduce the effort needed to acquire big data. REST is a software architecture commonly used to create APIs for web-based IoT applications. The REST API communication approach is based on hypertext transfer protocol (HTTP). RESTful web services are among the most popular interfaces in IoT, particularly when applications involve the cloud.
The various models in Advantech’s WISE-4000 series provide the necessary functions for cloud integration services. Furthermore, compared with similar products on the market, the WISE product series ensures information security via encrypted data transfer, and it eliminates additional expenses incurred by IoT gateways, thus reducing single-point costs in data collection.
