Data loggers monitor up to eight connected sensors at one time
Highly reliable (three year warranty), affordable and easy to set up and use TCW210-TH data loggers have been announced by Teracom. The data loggers are suitable 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.
“Our new TCW210-TH data logger device has a very intuitive setup process and is so easy to configure that most customers will never need to open up the manual,” said Ognyan Dimitrov, CEO of Teracom. “The humidity and temperature records can be monitored on the WEB interface of the device. There is no need for special software and conversions – you only need a standard web browser like Chrome, IE or Firefox.”
Utilising 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 ten items.
The logger utilises 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. 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.
