Querx TH
Web Thermometer, Hygrometer and Data Logger
Querx TH measures temperature and humidity precisely, calculates the dew-point and makes all the data available via LAN.
The smart sensor features an integrated data logger, alert functions and several interfaces for manual or automated data access.
The autonomous device is configured and controlled via a graphic web interface.
Querx TH supports various cloud providers. This makes it possible to access data via web, app or API from anywhere and at any time.



Features
[-]
Reliable Data Logging
Querx TH gathers temperature and humidity values, calculates the dew-point and makes all the data available via LAN.
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 51 days 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 TH 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 dweet.io, Palamoa or ThingSpeak. 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 TH sends emails, SNMP traps and Syslog messages to notify you when
- customizable threshold values for temperature, humidity and dew-point are transgressed
- the temperature or humidity 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 TH 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 TH features integrated sensors for temperature and humidity.
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.
Easy Installation
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.
Extended Temperature Range
The smart sensor works reliably, even in adverse conditions. Querx TH functions in temperatures between -40 °F and +185 °F (-40 °C and +85 °C).
Low Power Consumption
Querx TH is very energy efficient. The power consumption is less than 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.
