Ethernet data logger TCW210-TH


Model Ethernet data logger TCW210-TH

TCW210-TH is a temperature and humidity data logger for general environmental monitoring.

Short Description

TCW210-TH is a temperature and humidity data logger with an Ethernet interface for communication. Real-time data and charts of temperature, humidity and dew point can be monitored with a standard web browser (no special software is needed).

The device records all monitored parameters in an internal FLASH memory. The records are made on the previous set time interval and/or on an alarm condition. The capacity of memory allows at least 36 days log with records on every 1 minute. The log file can be periodically uploaded on a dedicated server by HTTP Post.

The logger utilizes a circular buffer in FLASH memory. When it is full, the new data overwrites the oldest one. In this manner FLASH memory stores a full log all the time. There isn’t a command to clear the log for security reasons. A copy of the full log is always available for downloading.

TCW210-TH supports temperature or temperature-humidity sensors. All sensors can be connected either to 1-Wire interface or to more robust MODBUS RTU over RS485. The maximum number of sensors is 8. Either of the two interfaces may be used.

TCW210-TH can initiate a connection (HTTP Post) to remote dedicated servers. The payload of this post is XML or JSON file. The files contain current values of monitoring parameters. HTTP post can be sent periodically or on previous set alarm conditions. Standard protocols as SNMP, MODBUS/TCP, and HTTP/API are also available for M2M applications.

TCW210-TH supports communication with ThingSpeak server. Four different parameters (channels) can be processed simultaneously. How to install a local ThingSpeak server can be seen here.
