TCW210-TH-R1.16- November 2022 Page 1
1. Introduction
TCW210-TH is a temperature and humidity data logger with an embedded WEB server. Real-time data
and charts of temperature, humidity and dew point can be monitored with a standard web browser
(no special software is needed). Standard protocols as SNMP, MODBUS/TCP, and HTTP/API are
available for M2M applications. The device supports also interface to popular IoT analytics –
ThingSpeak.
The Ethernet temperature logger supports up to eight temperature or humidity-temperature sensors.
All they can be connected either to the 1-Wire interface, popular for home automation or to more
robust MODBUS RTU over RS-485.
All monitored parameters can be recorded, in internal FLASH memory. The records are made on the
previous set time interval and/or on an alarm condition. The memory is large enough for at least 36
days with records on every minute. The log file can be periodically uploaded on a dedicated server by
HTTP/HTTPS Post. The stored data can be monitored on 4 graph pages.
XML/JSON file with all monitored parameters can periodically upload to a dedicated server by
HTTP/HTTPS Post.
For every monitored parameter e-mails and SNMP traps for up to 5 recipients can be sent. Alarm alert
can also be sent by HTTP/HTTPS Post with XML/JSON status files.
