Data acquisition has played a key role throughout the IoT era. Increasingly more devices are being interconnected and wireless applications have become the preferred network solution.As a leading provider of IoT solutions, Advantech continues to develop a wide range of wireless sensing devices for various application fields in order to offer customers the latest solutions to complete their IoT application systems
To send data from devices to the cloud or widely deployed aggregate devices, one might be afraid that an IoT system would become overly complex. However, with WISE-4000's cloud access ability, data can be transmitted directly to the cloud without the need for a gateway.
In IoT, the purpose of data acquisition is to connect data to the cloud in order to improve managerial efficiency. The WISE-4000 provides a wireless communication interface, IoT protocols, and pre-integrated major cloud service connectivity to facilitate connecting data to the cloud.
As the primary source of big data, data sensing plays a key role in the realization of IoT systems. To obtain different types of data for different IoT applications, conventional automation architecture and basic data acquisition alone are no longer sufficient, which is why Advantech has developed the WISE-4000 wireless sensor node (WSN). Based on the latest IoT concepts and technology, the WISE-4000 is a cloud-ready data sensing and communication tool that can help you realize your IoT system.
To provide complete IoT sensing solution, the WISE-4000 series goes beyond providing a wireless communication interface for sensors—it also provides cloud connectivity for additional user applications. With support for IoT protocols such as REST and MQTT, the WISE-4000 series can communicate with cloud services or other web services via secure web sockets. The WISE-4000 series comes with pre-integrated APIs for major cloud service providers (e.g., Dropbox) and IoT cloud services (e.g., Azure IoT Hub) and provides support for both private cloud platforms (e.g., private file servers or databases) and ERP/MES systems.
Modbus is an automation protocol widely used in PLC communication and SCADA systems. It adopts master–slave system architecture, in which the master polls individual slave devices to determine their status. In such systems, slaves do not send messages unless they have been polled
The REST communication approach can take advantage of not having to leverage much bandwidth while transmitting data. With RESTful web API in JSON format, data can be easily integrated to IoT services and optimized for use over the Internet. Additionally, REST support HTTPS or TLS, which improve security while publishing or retrieving data between devices and the cloud. Furthermore, it also enables end devices to publish data actively.
