PESSL Instruments GmbH, located in Weiz, Austria, has been producing reliable measuring instruments for 40 years. It is specialized in the development of innovative products in the field of agricultural monitoring and precision farming. PESSL has developed various devices for the measurement and monitoring of different agricultural parameters. More than 40,000 stations in 86 countries from all over the world have been supplied with PESSL’s products by more than 150 distribution partners. Together, PESSL and its daughter companies have 155 employees, developing and manufacturing high-quality products, and organizing worldwide marketing and sales. The instruments of PESSL are available under their brand name, METOS®. The instruments are used in a variety of fields, from agriculture to logistics, from research to large companies. Based on the PESSL chain interface, the connection of various sensors is possible. The products collect data, report them to the web platform and mobile application FieldClimate (, and make them available for optimized environmental management including demand-driven irrigation, plant protection, crop and insect monitoring.

Given PESSL’s extensive experience in research, technology development, prototype manufacturing, and testing, as well as a technical and economic assessment of innovative technologies, the company offers the right skills, knowledge, and infrastructure to support the STELLA project.

PESSL is one of the leading IoT providers for agriculture offering innovative and cost-effective solutions for more efficient farm management. Participating in the STELLA a project gives PESSL a chance to put into the farmer’s disposal all its expertise on sustainable agriculture and fulfill its mission to offer high-added value and customized cost-effective solutions and contribute to global environmental protection.


Pessl Instruments’s primary roles involve:

1. Utilizing IoT Devices for Data Collection:

  • Pessl Instruments contributes to Task 2.1 (Data Collection Protocols) by co-developing three IoT protocols for field-level data acquisition using various sensors. These IoT protocols ensure standardized and efficient data collection, adjusted for geographical variability and crop type.
  • Pessl Instruments will develop and provide the project with novel smart insect traps to detect and monitor the insect vectors of the examined crop diseases. These traps will use different attractants (sound, color, or pheromone), based on the different insects-vectors’ specificities, to achieve maximum trapping efficiency.
  • In addition, Pessl Instruments will provide spore traps to monitor airborne fungal spores concentration to identify the onset of the fungal diseases and to monitor their progression over time. Spore traps will be analyzed using analytical molecular methods (PCR, ELISA) to determine the type and concentration of fungus.
  • Finally, gathering, extracting, and pre-processing all the IoT and trap (insect and spore) data collected is part of the responsibilities of Pessl Instruments. Both traps (insects and spores) will help the development of accurate crop pest models from task T2.3.
  • The collected data feeds into the STELLA database – task T2.5 and WP3 – for further use in modeling and analysis.

2. Developing and Providing a Mobile Application:

  • Pessl Instruments leads Task 2.4, focusing on the development and modification of the smartphone application for crowdsourcing data collection.
  • The app facilitates data collection from UCP fields and global fields, recognizing selected pests and utilizing GPS capabilities for spatial distribution understanding.
  • Compatible with iOS and Android devices, the app will enable stakeholders to capture and upload images of healthy and damaged plants to the STELLA platform for further processing.
  • Pessl Instruments is responsible for app monitoring, updates, and implementation of protocols.
