Likewise, disturbance variables during the ensiling process and after removal are detected at an early stage and can be eliminated before a reduction in silage quality occurs. The use of a common software standard in harvest data management also ensures that the sensor data can later be integrated into already established software solutions and thus transferred directly into practice. Sensor system for monitoring the ensiling process in biogas production © Fraunhofer IZM bonding technologies, laser soldering, and soldering in different environments. Typical applications are the assembly of laser and photodiodes, laser bars, sensors, VCSEL, and MOEMS. The applications range from basic research and development of innovative semiconductor products to fully automated production environments with high throughput. ESYS GmbH develops and manufactures low-energy minaturized electronics with a focus on mobile applications. Since 1992, the Berlin-based company has been successfully implementing its own standard products as well as customer-specific hardware and software developments. These include in particular battery-powered long-term miniature data loggers for temperature, humidity, motion, acceleration, shock, and position. They are used, for example, for the remote location and fleet management of vehicles, machines, and containers. Applications for Sensors Sensor network for high voltage lines The autonomous sensor network ASTROSE monitors operation-relevant parameters of high-voltage overhead lines in order to make optimum use of their transmission capacities. Field trials have shown that capacity reserves can be raised by as much as 20% in this way. For this system developed jointly with colleagues from Fraunhofer ENAS and First Sensor Microelectronic Packaging, software tools are provided for storing the acquired data in a relational database. In addition, a user interface for better visualisation and more complex evaluation of the data has been created. In a further development with partners DResearch in Berlin and LTB in Neuenhagen, the system is currently being equipped with an image sensor for visual environment detection. Sensors are with us everywhere we go today: from position and GPS sensors in smartphones to highly specialised systems for various product categories, our lives and the modern economy can no longer be imagined without sensors. The number of applications seems enormous. However, a few basic principles can be observed: sensors need to be small, robust, and precise and have good connectivity. The development and optimisation of the corresponding technologies is underway at a large number of companies and research institutions in Berlin Brandenburg. With their work, they will also secure a technological lead for the region in the future. New sensors for agriculture The quality of the silage-making process is decisive for the efficient production of biogas. Until now, there has been no suitable sensor system that could monitor the silage process from the opening of the silo to the removal of the silage. With the multisensor technology developed by Fraunhofer IZM, the Julius Kühn Institute in Braunschweig, and ESYS GmbH, it is now possible for the first time to monitor compaction at critical points such as edge areas during Contact: Peter Krause Spokesperson Focus Area Microelectronics and Microsystems Technology Phone: +49 (0)3877 567460 E-mail:
