The WIN-SN-TNH-E is a networked environmental sensor module engineered for precise and reliable monitoring in industrial, agricultural, and smart building applications. It functions as a communication gateway, converting sensor data from its onboard or external I2C interfaces into standard industrial protocols like Modbus TCP and MQTT, enabling direct integration with SCADA systems, PLCs, and cloud IoT platforms. Its robust design ensures stable operation in electrically noisy environments typical of manufacturing floors or greenhouses.
Built around a core microcontroller with Ethernet PHY, the module provides accurate temperature and humidity readings, with sensor data typically scaled for high resolution (e.g., readings in multiples of 10 for 0.1°C/0.1%RH precision). The dual 5V USB-C and 12V DC power inputs offer installation flexibility, from PoE-enabled setups using a splitter to traditional 12V industrial power supplies. The compact, sealed enclosure protects the internal electronics, making it suitable for a wide range of mounting scenarios.
