Precise control of temperature, humidity and CO₂ levels is the foundation of modern greenhouse cultivation. But what if the measurement data is scattered, the infrastructure too complex, and rapid response impossible without physical presence on site? In this case study, we show how we solved these problems with automation based on Single Pair Ethernet (SPE) and Cloud technologies. Learn how to simplify your climate monitoring system, reduce resource consumption and gain full control of your greenhouse - from anywhere and in real time. Read on!
Agriculture today faces major challenges. Climate change, increasing sustainability requirements and pressure to increase yields while reducing resource consumption require innovative solutions. Today's greenhouses are no longer just enclosed spaces for growing crops, but advanced production environments where precise monitoring and automation of processes are crucial.
In response to these challenges, our client was looking for a solution that would allow:
ensure continuous and precise monitoring of key environmental parameters in the greenhouse, such as temperature, humidity and CO₂ levels,
integrate distributed sensors into a single, cohesive system that allows easy access to data from different zones of the facility,
simplify the communications infrastructure by using modern data and power transmission technologies (Single Pair Ethernet),
monitor and optimize water and fertilizer use to reduce costs and environmental impact,
enable remote access to data and automation of cultivation processes, minimizing the need for manual intervention.
To provide a complete picture of greenhouse conditions, we implemented a system based on humidity and temperature sensors with a C02 JUMO hydroTRANS module. Communication between the devices is via a Single Pair Ethernet interface, which allows simultaneous data transmission and sensor power supply via a single cable.
Completing the system is a JUMO flowTRANS MAG H20 electromagnetic flow meter with SPE interface, which is used to monitor the flow of fertilizer in the watering system. All data goes directly to the IIoT[KS2] (Industrial Internet of Things) platform for secure process management in the JUMO Cloud.
The use of JUMO Cloud allows greenhouse operators to use intuitive tools for data visualization and analysis. This makes it possible not only to monitor real-time conditions on an ongoing basis, but also to implement predictive control. For example, irrigation and fertilization schedules can be dynamically adjusted based on the current state of the plants and the impact of environmental factors. System integration is supported by Weidmüller's SPE switches, which provide seamless connections between sensors and the cloud.
To provide a complete picture of greenhouse conditions, we implemented a system based on humidity and temperature sensors with a C02 JUMO hydroTRANS module (907042).
By integrating with JUMO Cloud, greenhouse operators gain instant access to measurement data - from anywhere, at any time. The system allows convenient viewing of real-time environmental parameters via a web interface, without the need to install additional software.
Built-in visualization and predictive analysis tools allow the user to anticipate plant needs and dynamically adjust irrigation and fertilization systems. Users can automate watering schedules and control the amount of fertilizer delivered based on current greenhouse microclimate data.
Remote operation of the entire system significantly reduces time-consuming daily supervision, resulting in lower operating costs. At the same time, the reduction in water and fertilizer use promotes the goals of sustainable agriculture - while maintaining high yields and crop quality.
The use of Single Pair Ethernet (SPE) technology has significantly simplified the communications infrastructure in the greenhouse. It has reduced the number of intermediary devices and cables, and increased the reliability of the entire system. This solution is particularly well suited for extensive and environmentally challenging facilities, such as modern cultivation complexes.
The main advantages of SEN are:
With SPE, the entire automation infrastructure becomes more flexible, easier to expand, and better suited to future technology requirements.
