Description

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.

Key Features

  • Industrial Communication Protocols: Comprehensive support for Modbus TCP, Modbus RTU over RS485, MQTT, HTTP, UDP, and SNMP ensures compatibility with virtually any control or monitoring system.
  • Expandable I2C Sensor Interface: Hosts popular digital temperature/humidity sensors (AHT21, SHT2x, BME280/680) for precise environmental data acquisition and air quality monitoring.
  • Versatile Dual-Supply Architecture: Accepts 5V via USB Type-C for convenient setup or 12V DC for robust industrial power rail integration, with wide input voltage tolerance.
  • Network-Robust Data Transmission: Ethernet interface provides reliable, long-distance data transfer with high noise immunity, superior to typical wireless sensor nodes.
  • Local Visualization Support: Outputs data via its RS485 Modbus RTU port to drive external LCD or TFT displays for onsite monitoring without a network connection.
  • High-Resolution Measurement Output: Delivers sensor readings with enhanced resolution (e.g., actual value = register value / 10), enabling fine-grained trend analysis.
  • Durable Compact Housing: The 85x85x35.5 mm enclosure is designed for mechanical strength and offers multiple mounting options for panel or DIN-rail installation.

Applications

  • Industrial Facility & Server Room Monitoring: Continuous temperature and humidity logging for climate control and equipment protection, integrated directly into plant-wide SCADA via Modbus TCP.
  • Smart Greenhouse & Agricultural Automation: Centralized node for monitoring Grow room conditions, with data published via MQTT to cloud dashboards for irrigation and ventilation control.
  • HVAC System Performance Verification: Installed in air handling units (AHUs) and ductwork to provide networked feedback for Building Management Systems (BMS) using SNMP or HTTP.
  • Laboratory & Cleanroom Environmental Assurance: Provides precise, networked sensor data for compliance logging and alarm generation in sensitive controlled environments.
  • Retail & Warehouse Cold Chain Monitoring: Ethernet-connected sensor node for tracking temperature and humidity in perishable goods storage, with data accessible via web server (HTTP).

Frequently Asked Questions

What communication protocols does the WIN-SN-TNH-E support?

The module supports a comprehensive suite of industrial and IoT protocols including Modbus TCP for direct Ethernet integration, Modbus RTU over its RS485 interface, MQTT for cloud publishing, HTTP/ASCII for web services, UDP for lightweight messaging, and SNMP for network management systems. This allows seamless connection to PLCs, SCADA, BMS, and IoT platforms.

Can I use my own I2C temperature sensor with this module?

Yes, the module features a standard I2C interface designed to host popular digital sensors like the AHT21, SHT2x series, BME280, or BME680. You must ensure the sensor's I2C address is configured correctly within the module's firmware. The module reads the sensor data and makes it available via all its supported communication protocols.

What are the power supply requirements and how do I connect it?

The module offers dual power input options. You can use a standard 5V USB Type-C cable for convenient power, or connect a 12V DC power supply to the terminal block. The 12V input is recommended for industrial installations for better noise immunity and longer cable runs. Ensure the power source provides adequate current (typically >100mA).

How is the sensor data formatted and scaled in the Modbus registers?

Sensor readings (temperature and humidity) are typically provided in the Modbus holding registers as integer values scaled by a factor of 10. For example, a temperature reading of 234 in the register corresponds to 23.4°C. You must divide the register value by 10 in your host system (PLC, HMI, or software) to obtain the actual physical measurement.

Is this sensor suitable for outdoor or harsh environment use?

The module itself is housed in a compact plastic enclosure designed for indoor or protected outdoor use (e.g., inside a weatherproof enclosure). For harsh environments, the critical factor is the external I2C sensor you attach. You would need to select an externally mounted sensor with an appropriate IP rating (e.g., IP67) and connect it via cable to the module's I2C pins inside a protected enclosure.
