2.4/5GHz Wi-Fi Temperature and Humidity Sensing Module Advantech WISE-4250-S232
The WISE-4250 series is a wireless IoT solution designed for industrial applications. This Ethernet-based device is compatible with various I/O and sensors and integrates data acquisition, processing, and publishing functions. It supports real-time P2P communication between devices, enabling edge intelligence without a central controller, making it ideal for applications requiring rapid response and distributed control. Furthermore, a watchdog timer and smart roaming ensure stable device operation in any environment. The WISE4250 also prioritizes data security, with a data logger, data recovery function, WPA3/TLS1.3 encryption, and IP whitelisting to prevent data loss and unauthorized access. Best of all, it supports MQTT, Modbus, and RESTful APIs, enabling you to easily publish data to various cloud platforms for data-driven decision-making.
