“…For 866 MHz, the attenuation drops to −8.3 dB/m and for 433 MHz to −2.2 dB/m. Sub-GHz sensors with Lora, Dash7 and proprietary protocols were successfully tested to penetrate a stack of apple crates over 2 to 5 meters (Jedermann et al 2018).…”

“…LoRaWAN (long-range wide-area network) allows communication with low data rates in license-free sub-GHz frequency bands. We demonstrated that LoRa radio signals could penetrate 4.5 meters of fruits with only moderate packet losses of 1.5% (Jedermann et al 2018), making it a highly suitable candidate for communication with packed food products inside a container. However, LoRaWAN has been, so far, mostly applied to the outside communication of containers, e.g., on the vessel or in harbour settings, where cellular networks are not available (Avery 2020).…”

Food losses in the cool chain, which are mostly caused by temperature deviations, can be reduced by remote monitoring of transport conditions. The project ‘Intelligent Container’ was begun 15 years ago to provide the necessary sensor system, communication and automated evaluation of data. If transport and delivery planning are adjusted according to the actual quality or the predicted remaining shelf life, more products arrive with sufficient quality at the customers. This paper summarizes the project results and highlights current trends in industrial application and research, such as commercial remote container monitoring and standards for data exchange, sub-GHz communication, the increasing availability of biological and computational fluid dynamics models and digital twins. Open research topics include the development of specialized sensors. To overcome obstacles hindering the industrial application of sensor quality monitoring, we suggest a gradual approach, with lower company resources required for the first action points. Food losses can be reduced, even if the complete system, including permanent remote access and adaptive stock rotation, is not applied.

“…Internet of Think (IoT) is the concept of an object that has the ability to transfer data through a network in the form of interaction between machines [8]. In the application of IoT many communication technologies between systems that can be used, one of which is LoRa (Long Range) [9]. LoRa is a modulation process using FM modulation [10].…”

Industrial waste is one of the causes of water pollution. Such waste requires periodic and continuous surveillance so that it can be followed up for specific treatments. This research develops LoRa (Long Range) technology for monitoring waste water based on geographic information system. Sensors used in this research are turbidity, pH, and temperature sensors. The result of this research is a system capable of displaying and mapping the conditions of waste water under surveillance. Alerts are generated when the quality of waste water reaches a threshold value set to the owner of the factory. The accuracy of the turbidity sensor under test is 93.42%.

Saat ini penerapan teknologi komunikasi LoRa sedang mengalami peningkatan di segala bidang, karena LoRa mempunyai keunggulan daya rendah dan jangkauan jauh. Namun pada umumnya, penerapan tersebut hanya menganalisis unjuk kerja transmisi data LoRa pada kondisi node pemancar dan penerima yang diam di tempat. Oleh karena itu, penelitian ini secara khusus membahas penerapan transmisi data LoRa pada node yang bergerak untuk mengetahui pengaruh kecepatan gerak node terhadap unjuk kerja transmisi data LoRa. Satu buah transmitter node yang terus-menerus mengirimkan paket data akan digerakkan pada suatu lintasan lurus menjauh dari sebuah receiver node yang diam. Kemudian pada receiver node, nilai packet loss dan throughput dari semua paket dihitung untuk mengukur unjuk kerja transmisi data. Berdasarkan hasil perhitungan rata-rata dari semua percobaan, nilai kecepatan node yang tinggi pada percobaan lintasan lurus menghasilkan nilai packet loss yang semakin rendah dan nilai throughput yang semakin besar.
