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.
