Efficiency is not only a crucial topic in industrial production, JUMO and Weidmüller demonstrate how smart sensors and Single Pair Ethernet (SPE) simplify monitoring and control in greenhouses and also optimize resource use and increase yields.
Sensor technology as the key to success
The basis of every successful greenhouse operation is the precise monitoring of the ambient conditions. This is possible with the innovative hydroTRANS sensors from JUMO. The sensors record essential parameters such as temperature, humidity and CO2 content. These values are crucial for the optimal development of the plants.
A special feature of JUMO solutions is the integration of Single Pair Ethernet technology. SPE enables direct and lossless data transmission from the sensor to the cloud - without complex intermediate systems such as edge gateways. Liquid fertilizer can also be monitored using a magnetic-inductive flow meter with an SPE interface, which increases efficiency and minimizes waste.
Single Pair Ethernet: The technological basis
Single Pair Ethernet is a pioneering transmission method that was specially developed for industrial applications. It is characterized by the following advantages:
- Extended range: With a range of up to 1,000 meters over a single pair of copper wires, SPE far exceeds conventional Ethernet. This is particularly important in large-scale greenhouse systems.
- Direct data transmission: Data goes directly from the sensor to the cloud without any intermediate steps, which reduces installation effort and increases data integrity.
- PoDL functionality (Power over Data Line): In addition to data transmission, SPE also enables the sensors to be supplied with power via the same cable. This eliminates the need for additional power lines - a clear advantage in the warm, humid environment of a greenhouse.
Cloud-based solutions for maximum efficiency
The data recorded by the sensors is transferred directly to the JUMO Cloud via SPE. There, greenhouse operators have access to intuitive visualization and analysis tools. These not only enable real-time monitoring, but also predictive control. For example, irrigation and fertilization plans can be adjusted based on the current plant health and environmental conditions.
Weidmüller supports this process with its SPE switches. These enable a seamless connection between sensors and the cloud. Weidmüller's "unmanaged switches" in particular make installation and integration easy, even for users without in-depth IT knowledge.
More yield through targeted automation
The collaboration between JUMO and Weidmüller impressively shows how IIoT solutions not only increase efficiency, but also contribute to more sustainable agriculture. The precise control of water and fertilizer resources minimizes waste while ensuring better yields. "These intelligent solutions are revolutionizing the way greenhouse operators work. They make it possible to manage resources in a way that conserves resources while increasing productivity," explains Dr. Thomas Bürger, Head of the Automation Products and Solutions Division at Weidmüller.
In practice, the integration of SPE and sensors means that water shortages or excessive CO2 levels can be immediately detected and regulated. The precise dosing of water and nutrients ensures that plants only get what they really need. This creates optimal growth conditions that directly translate into higher yields.
Conclusion: The future of agriculture is smart
The combination of modern sensors and Single Pair Ethernet is setting new standards for efficiency and sustainability in agriculture. JUMO and Weidmüller have shown how innovative technologies can make greenhouses future-proof. With solutions that not only increase yields but also minimize the use of resources, they are making an important contribution to the agriculture of tomorrow.
