MOBImess – Mobile Climate Measurement Network Jena

PIKOBYTES and ERGO Umweltinstitut GmbH developed a mobile, vehicle-based measurement system for the Thuringian State Office for the Environment, Mining and Nature Conservation (TLUBN) for small-scale urban climate measurement. The completely self-sufficient sensor nodes continuously generate a dense data set that is used in Jena and other cities in Thuringia to determine urban heat stress.

Project contents

As part of the project, eight mobile and solar-powered sensor nodes were set up in accordance with TLUBN specifications, which can be mounted on streetcars or waste disposal vehicles and continuously measure temperature and humidity. The operating environment of the measuring stations is challenging, as there is no continuous mobile phone coverage and the devices on the streetcars are permanently exposed to metal dust caused by abrasion from the overhead lines. The devices installed on waste disposal vehicles have to withstand strong vibrations and occasional impacts from branches protruding into the driving area.The sensor nodes operate in an energy-optimized manner and take the specific driving situation into account during data acquisition: a measured value is recorded every 20 seconds when the vehicle is moving and every hour when it is stationary. In addition, depending on the energy budget, the data is transmitted via mobile radio every 6 or 24 hours, saved and pre-processed for further evaluation. The devices are serviced annually and the sensors are calibrated. Calibration is carried out using software and can be easily adapted if necessary.The project was realized in cooperation with ERGO Umweltinstitut GmbH, whereby our partner ERGO is primarily responsible for the construction and maintenance of the measuring devices as well as the functional testing. PIKOBYTES is primarily responsible for data transmission, data management and firmware programming. Development and support of the overall system are carried out in close cooperation.

The then Environment Minister Anja Siegesmund installed the first measuring device on a waste disposal vehicle belonging to Kommunalservice Jena.

PIKOBYTES operates an IoT hub for data transmission, which receives the data via UDP. All raw data is archived and stored in a PostgreSQL database for evaluation and analysis. The calibration data of the devices is also stored there in a versioned format, so that a reprocessing of the data with corrected calibration can be initiated at any time. Evaluations are calculated several times a day on this database and provided to TLUBN on an ongoing basis.
