The device supports temperature sensors and combined temperature-humidity sensors, which can be connected through the 1-Wire interface or through the more robust MODBUS RTU over RS485. The maximum number of sensors is 8, regardless of which interface is used, providing excellent flexibility for different environmental monitoring projects.

All monitored parameters can be recorded in the internal FLASH memory. Records can be made at predefined time intervals and/or on alarm conditions. Memory capacity allows at least 36 days of logging with records every 1 minute, using a circular buffer that keeps a full rolling log at all times. The log file can be downloaded and also uploaded periodically to a dedicated server through HTTP Post in XML or JSON format.

Key benefits

• Real-time monitoring of temperature, humidity and dew point.
• Live data and charts available through a standard web browser.
• Support for up to 8 sensors via 1-Wire and/or MODBUS RTU.
• Internal FLASH memory logging with rolling history.
• Capacity for up to 70,000 records.
• HTTP Post data upload in XML or JSON format.
• Integration with SNMP v2, MODBUS TCP/IP and HTTP/API.
• SNMP trap alerts to up to 5 recipients.
• Secure email transfer with TLS 1.0 / 1.1 / 1.2.
• Compatible with ThingSpeak and TC Monitor.

Recommended applications

The TCW210-TH is designed for projects where continuous monitoring, reliable logging and remote access are essential. It is especially suitable for:

• SOHO environmental monitoring.
• Industrial process data logging.
• Data centre environmental monitoring.
• Temperature and humidity control in food and beverage storage.
• Integration in M2M, supervision and automation systems.

Technical and functional advantages

The TCW210-TH combines data logging, graphical presentation, Ethernet communication and industrial protocol support in one compact unit. Browser-based access simplifies remote management, while support for both 1-Wire and RS485 MODBUS RTU expands compatibility with a wide range of sensors and installations.

Its circular FLASH memory buffer ensures that the most recent log is always available without interruption, while preventing manual log clearing for security reasons. Remote HTTP Post upload, NTP, Dynamic DNS support and browser-based firmware updates make this logger particularly suitable for distributed monitoring and remote maintenance.
