Reliable Data Logging

Querx WLAN THP gathers temperature, humidity and air pressure values, calculates the dew-point and makes all the data available via LAN or WiFi. Hence, the device can be used in locations without access to a wired network.
The minimal, maximal and average values are stored on the device at one minute intervals, including a timestamp. The integrated storage can hold the data of at least 3.8 years and all data is safe even in the event of a power shortage.

Data Visualization

The web interface visualizes all gathered data in an interactive graph. Modern technology standards such as HTML5, CSS3 and SVG facilitate data access via the web browser on your computer, tablet or smartphone.

Data Export in Various File Formats

Querx WLAN THP can export data, making further processing and archiving simple. The CSV format is suited for spreadsheet software such as Excel. The XML format enables further automated processing in customized software solutions.

Suitable for Monitoring Systems

The data is provided via M2M systems. The sensor can be integrated into network management systems such as Zabbix or Icinga via SNMP. Modbus/TCP allows to use the device in the industrial sector via SCADA. All logged and current data can be accessed from Python, PHP and other programming languages via HTTP.

Cloud Interfaces

If required, all data can be sent to Internet-Of-Things clouds such as ThingSpeak or dweet.io. This feature makes it possible to access data around the globe and integrate all data into custom projects via the programming interfaces provided by the cloud services.

Diverse Alerts

Querx WLAN THP sends emails, SNMP traps and Syslog notifications and also features optical and acoustic alerts that are triggered when
-customizable threshold values for temperature, humidity, air pressure and dew-point are transgressed
-the temperature, humidity or air pressure values rise or fall too quickly
-the values return to their normal state.

Encrypted Email Alerts

Up to four recipients can be informed of any occurring alerts via two mail servers. Notifications can therefore be sent even if one server should fail.
The alert emails are encrypted. Customizable text-variables let you create meaningful notifications.

Simple Operation via Web Interface

Configuring and operating Querx WLAN THP is intuitive. The user interface is self-explanatory and additionally features an in-depth online help section.

Quick Setup

Integrating the smart sensor into existing networks requires no complicated configuration. It supports mDNS / Bonjour, allowing for automatic detection and DHCP network configuration.

Quality Sensors

Querx WLAN THP features integrated sensors for temperature, humidity and air pressure.

Accredited Calibration upon Request

Calibration is a vital component of quality control. DAkkS certificates (German accreditation body) are available for all Querx devices. They can be purchased together with the device or at a later date.

Extended Temperature Range

The smart sensor works reliably, even in adverse conditions. Querx WLAN THP functions in temperatures between -40 °F and +185 °F (-40 °C and +85 °C).

Low Power Consumption

Querx WLAN THP is very energy efficient, using approximately 1 W. An unused USB port or an external wall plug power supply can be used to power the device.

Always up to Date

The Querx firmware is continually updated and adapted to current developments. New versions of the firmware are made available periodically. The web interface tells you what version Querx is currently running and lets you update the firmware.
