TCW210-TH is a temperature and humidity data logger with an Ethernet interface for communication. You can monitor real-time data and graphs of temperature, humidity, and dew point with a standard web browser (no special software is required). The device records all monitored parameters in its internal FLASH memory. Recordings are made at the previously set time interval and/or under an alarm condition. The memory capacity allows for at least 36 days of logs with records every 1 minute. The log file can be periodically uploaded to a dedicated server via HTTP Post.

The logger uses a circular buffer in the FLASH memory. When full, new data overwrites the oldest. This way, the FLASH memory always stores the complete log. There is no command to clear the log for security reasons. A copy of the complete log is always available for download.

TCW210-TH supports temperature or temperature-humidity sensors. All can be connected to the 1-Wire interface or the more robust MODBUS RTU over RS485. The maximum number of sensors is 8, and it is irrelevant which of the two interfaces will be used. TCW210-TH can initiate a connection (HTTP Post) to remote dedicated servers. The payload of this post is an XML or JSON file. The files contain the current values of the monitoring parameters. The HTTP message can be sent periodically or based on previously set alarm conditions.
Standard protocols such as SNMP, MODBUS/TCP, and HTTP/API are also available for M2M applications. TCW210-TH supports communication with the ThingSpeak server. Four different parameters (channels) can be processed simultaneously.
