Web Thermometer, Hygrometer, Barometer and Data Logger
Querx THP measures temperature, humidity and pressure precisely and calculates the dew point.
The smart sensor features an integrated data logger, alert functions and several interfaces that allow for manual or automated data access.
The device is controlled and configured via a graphical web interface and can operate autonomously.
Querx THP supports various cloud services. This makes all data accessible globally at any time, via web, apps and APIs.
Interactive Data Visualization
The web interface displays all tracked measurements in an interactive graph. The latest standards such as HTML5, CSS3 and SVG facilitate access to the interface via your PC, tablet or smartphone.
Querx THP provides access to data via M2M-interfaces. SNMP support lets you integrate the sensor into network management systems such as Zabbix or Icinga. The device can also be applied in the industrial sector via SCADA systems, due to the integrated Modbus/TCP interface.
Data Export in Several Formats
Recorded measurements can be exported for further external processing and archiving. The CSV format is compatible with spreadsheet applications such as Excel. The XML format makes it possible to process data automatically in customized software solutions.
Reliable Data Tracking
Querx THP tracks temperature-, humidity- and pressure-values and calculates the dew point. All data can be accessed via LAN.
If required, all data can be transmitted to the Internet of Things services ThingSpeak and Xively. This lets you access your data globally and facilitates the integration into custom software systems via the interfaces provided by the cloud services.
Querx THP can send emails, SNMP traps and Syslog messages to notify you if
-the temperature, humidity, pressure or dew point rises above or falls below configurable limits
-the temperature, humidity, pressure or dew point values rise or fall exceptionally quickly
-the values return to their normal range
Data Access via HTTP
All current and logged values can be retrieved in the XML, JSON and CSV file formats. This makes them accessible from the command bar and via Python, PHP or other programming languages.
Always up to Date
The Querx firmware is in continuous development and new functionality is frequently added. New versions are uploaded to the web periodically. You can determine which version your device is running and initiate an update right from the web interface.
Continuous Data Logging
The smart sensor saves the measured values once a minute. The minimum, maximum and average values are saved with a timestamp for at least 25 days and will not be lost, even if a power shortage occurs.
The Android and iOS apps Querx Discoverer and IoT Monitor give you access to all your recorded data from your smartphone.
Encrypted Email Alerts
Querx THP can notify up to four recipients of occurring alerts using two discrete email accounts. This ensures that alert notifications are sent even if one server fails.
The emails are encrypted (TLS / StartTLS).
The messages can be customized with text-variables, making them easily comprehensible.
Intuitive Operation via Web-Interface
Configuring and operating Querx THP is an intuitive process. The user interface is self-explanatory and a detailed online help section is also provided.
Querx THP can be integrated into existing networks without any configuration being required. The smart sensor can be detected automatically by mDNS / Bonjour and it can be configured automatically via DHCP.
Querx THP features integrated temperature-, humidity- and pressure-sensors. The sensors are oil repellent as well as splash- and dust-proof.
The case's small footprint makes it possible to install the sensor in confined spaces.
It can be fastened easily by using the slits on the casing.
Accredited Calibration Available
Calibration is an integral part of quality control. DAkkS-certification (German Accreditation Body) is available for Querx devices for a service-fee and can be purchased when ordering the product or at a later date.
Low Power Consumption
Querx THP is very efficient. The power consumption is less than 1W.
Extended Temperature Range
Querx THP works reliably even in unfavourable conditions. The device can operate at temperatures between -40 °F and 185 °F (-40 °C - 85 °C).
Power Supply via USB
An unused USB port or an external power supply can be used to power Querx THP.
