Teracom Announces TCW210-TH Temperature and Humidity Data Loggers

30 January 2018

Teracom LTD announces the availability of highly reliable (three-year warranty), affordable and easy to set up and use TCW210-TH data loggers for remote temperature and humidity monitoring applications.

Each TCW210-TH can monitor up to eight temperature and/or temperature-humidity sensors of various brands and types (up to 24 different parameters each) via either 1-Wire interface and/or the more robust MODBUS RTU over RS485. For example, four sensors can connect via MODBUS and another four can connect via 1-Wire, all at the same time.

Utilizing 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 utilizes 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 not a command to clear the log, and 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 are XML or JSON files. Standard protocols as 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.
