    Development and field evaluation of a multichannel LoRa sensor for IoT monitoring in berry orchards
    (41. GIL-Jahrestagung, Informations- und Kommunikationstechnologie in kritischen Zeiten, 2021) Shamshiri, Redmond R.; Weltzien, Cornelia
    Evaluation of long-range wireless transceivers with respect to their power consumption, network connectivity, and coverage under extreme field conditions is necessary prior to their deployment in large-scale commercial orchards. This paper reports on the development and field performance of an affordable multi-channel wireless data acquisition for IoT monitoring of environmental variations in berry orchards. A connectivity board was custom-designed based on the powerful dual-core 32-bit microcontroller with WiFi antenna and LoRa modulation at 868 MHz. The objective was to verify the possibility of transmitting multiple sensor readings with lower power consumption while increasing the reliability and stability of wireless communication at long distances (over 1.7 km). Collected data from the wireless sensor was compared and found to be consistent with measurements of a data logger installed in the same locations. The presented paper highlights the advantages of LoRa sensors for digital agriculture and the experience in real-time monitoring of environmental parameters in berry orchards.

    Key factors for personal health monitoring and diagnosis device
    (Mobile Computing in Medicine, Second Conference on Mobile Computing in Medicine, Workshop of the Project Group MoCoMed, GMDS-Fachbereich Medizinische Informatik & GI-Fachausschuss 4.7, 2002) Schwaibold, M.; Gmelin, M.; Wagner, G. von; Schöchlin, J.; Bolz, A.
    The current common goal in medical information technology today is the design and implementation of telemedicine solutions, which provide chronically ill patients with mobile services that enhance their quality of life, and support and optimize their treatment in case of emergency. Several projects being worked on by FZI and its partners will form a basis for a novel, individual and widespread health monitoring system, which can provide patients with 24h monitoring of their relevant physiological parameters, and therefore optimize their medical treatment and could possibly be life-saving thanks to the enhanced emergency management. In order to be able to build a successful platform for a wide range of medical applications in practice, key factors have been identified which will be introduced in this paper: micro-technological sensors, which are to be used in mobile applications, modularity, a wireless communication network, local intelligence in the form of a powerful mobile information unit, connection to a global network and a conclusive system design for improving the efficiency of health care-related procedures.
