TCW210-TH Temperature and Humidity Data Logger

Description

A highly reliable and easy-to-use data logger for remote temperature and humidity monitoring applications is the TCW210-TH. Each logger can monitor up to 8 temperature and/or temperature-humidity sensors of various brands and types (up to 24 different parameters each) via either a 1-wire interface and/or the more robust MODBUS RTU over RS485.

 

Using an Ethernet interface for web and network connectivity, the device monitors real-time data for temperature, humidity, and dew point, and records all monitored parameters using internal FLASH memory. The records can be made on set time intervals and/or on alarm conditions. The capacity of memory allows at least 36 days logged with data recorded once every minute. The log file can be periodically uploaded on a dedicated server by HTTP Post.

 

The device is supported by Android and iOS applications, as well as by Teracom’s remote and monitoring software TC Monitor, which provides a free license for up to 10 items.

 

The logger uses a circular buffer in FLASH memory (up to 70,000 records). When it is full, the new data overwrites the oldest one. In this manner, FLASH memory can store a full log all the time. For security reasons, there is no command to clear the log. A copy of the full log is always available for download.

 

The TCW210-TH can initiate a connection (HTTP Post) to remote dedicated servers. The payload of this post is XML or JSON files. Standard protocols SNMP, MODBUS TCP/IP, and HTTP API are also available for M2M applications. TCW210-TH also supports communication with ThingSpeak servers. Four different parameters (channels) can be processed simultaneously.
