Press release January 2025

First Single Pair Ethernet sensor for temperature
and relative humidity

Ethernet specialist Wiesemann & Theis launches its first SPE-capable thermo-hygrometer on the market. The innovative SPE technology enables end-to-end IP communication from the sensor to the cloud.

W&T introduces the SPE Thermo-Hygrometer as the first device from the range of SPE-capable components & sensors: With a combined thermo/hygro sensor, the device records temperature and humidity data, making it available via Single Pair Ethernet (10BaseT1L Full Duplex). Sensor data can be stored in the W&T Cloud on request, processes can be monitored directly in the browser and configurable alarms can be sent to a mobile phone via MQTT message or push notification.

The measuring device records values in the range of -40°C...85°C or 0...100% rH and is supplied with power via the data cable (SPoE Class 1). Thanks to low interference emissions, high interference immunity and optional ISO factory and DAkkS/DKD calibration, it is suitable for a wide range of applications in industrial environments and in the (Industrial) Internet of Things.

The pioneering SPE technology enables standardized Ethernet communication from the field to management, which makes corresponding gateways obsolete and reduces susceptibility to errors. The enormous transmission length of up to 1000 meters also saves on repeaters; the double-core SPE cables supply peripheral devices with power, which results in slimmer cables overall, more powerful and reliable applications.

The model with article no. 57723 is now available for purchase commercially for a net price of EUR 298.00 and can be tested free of charge for 30 days. More information at wut.de/57723 or +49 202-26 80 110.

Wiesemann & Theis GmbH was founded in 1979 by Reinhard Wiesemann and Rüdiger Theis. With 50 employees, the company produces microcomputer and network technology at its Wuppertal site. With the Web-IO 4.0 product line, the Wuppertal-based network specialist has long since succeeded in bridging the gap between classic automation
technology and Industry 4.0 / IoT.
