W&T Microwall:
Small firewalls protect devices and machines in the network
Microwall Gigabit from the Wuppertal network specialist Wiesemann & Theis marks the start of a new selection of user-friendly security products for industry and manufacturing. The small firewall isolates potentially vulnerable or non-secure devices and machines in their own network segments. Communication with these secure islands in the network is limited to the cases necessary to ensure operation. This effectively prevents attacks on open TCP or UDP ports as well as unwanted data connections.

Precise measurement of permanently high humidity over network

The Web-Thermo-Hygrometer ++ from Wuppertal Wiesemann & Theis GmbH records and monitors measured values ​​for temperature and humidity and provides them via various network interfaces. The drift-free humidity sensor has no saturation effects and is therefore suitable for precise long-term measurements even in environments with permanently high humidity. With deviations of only 0.1K and 0.5% RH both sensors are very precise.

New Web-IO 4.0 makes it easy to automate solutions

In recent months, Wiesemann & Theis GmbH has prepared the network-based remote control units and the Web-IO family sensor for thorough inspection. Web-IO 4.0 is now available and offers, in addition to new protocols and enhanced security, a new and simplified user interface.
New communication channels have been added to configure the necessary protocols and interfaces, such as email or MQTT. It is easy to decide how the Web-IO device should behave against a particular state or event. It may be that it should send an email if the temperature becomes too high - or turn off a digital output upon receipt of an MQTT subscription.

MQTT: Industry 4.0 you can touch

Terminal devices in the Internet of Things generally have no public IP address, but rather are connected over private networks. Cross-network connections can be opened only in the outgoing direction without a lot of additional effort. This eliminates peer-to-peer connections as a communication channel for the Internet of Things.

The solution is provided by the protocol MQTT: Terminal devices open a connection to a publically accessible messaging service, the broker. Here they can as publishers publish information and as subscribers subscribe to it.

Fatigue and reduced performance:

A frequent cause of fatigue and reduced performance in the office is stale room air. Higher CO2 values make you tired. In addition, odor-causing compounds result in distracting smells in enclosed spaces.



Air quality with VOC/CO2 The sensor always knows:

With the air quality sensor from W&T you always have a fix on air quality: VOC, volatile organic compounds measured and represented as CO2 equivalents, limit violations are indicated on a traffic-light type display, reported via email and are also available when needed from the W&T cloud. You no longer have to feel tired and listless at the office!

{tab Document Offline/Online}

 

Continuous availability everywhere

Continuous documentation of the measurement data in the online memory enables access to the measurement data anytime and anywhere.

Individual visualization

Views can be custom defined and diagrams and graphs combined as desired. Other authorized users also have access to your displays.

 

Measuring data storage local and online

Measurement values can be stored directly on the sensor and viewed when needed directly from your browser (without using the cloud). Limit violations are reported and displayed on the LED indicator located on the device.

Optionally you can automatically send the measurements from the device to the W&T cloud, save and document them there and report limit violations.
