1. About Querx TH
Querx TH measures temperature, humidity and calculates
the dew point. The alert function sends out notifications over
email (TLS / StartTLS), SNMP trap and syslog, if critical
thresholds are exceeded.
The internal memory stores at least 51 days of data. n
interactive web interface provides a graphical representation
of the logged data and the possibility to export it in the CSV
and XML file formats.
Cloud interfaces connect Querx TH to the Internet of Things
and allow world wide data access via web and ndroid pp.
Through SNMP, you connect Querx TH to network
management systems, such as Nagios or Zabbix.
Modbus/TCP allows usage in industrial environments
(SC D ).
