Each device can monitor up to eight 1-Wire and/or MODBUS connected sensors at one time. Applications include datacenter and SOHO environment monitoring, cold chain (delivery trucks, distribution, storage centers, retail stores), medical products storage and transport, industrial processes data logging, and many others. Teracom LTD today announced the availability of highly reliable (3-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. 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.
