Even more face-to-face learning, blended learning and distance learning have own advantages. The goal of each teaching team is a realization of learning combining the advantages of all three types of learning processes. For learning choosing, the wishes and possibilities of the students must be taken into account. Very often, for reasons beyond their control, they are not able to attend classes in person. The reasons may be their health condition, country borders closing, transport blockage, etc. This is another reason to develop different learning models that best meet the needs of individual groups of students. If it is necessary and if it is possible, these models can be combined. This will make the learning process more flexible and adaptable. As more flexible the learning process is, as more students will be able to benefit from it.Engineering training has its own specific requirements due to the practical orientation of the knowledge to be acquired. These requirements must also be taken into account when choosing a learning method.This paper proposes an opportunity for combined learning both face-to-face and distance learning. On this way theirs advantages are saved.","PeriodicalId":300010,"journal":{"name":"2020 28th National Conference with International Participation (TELECOM)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133486232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The batteries are short-lived, large in size, and bulky. But the most important thing is that batteries are extremely harmful to the environment. This necessitates the use of battery-free devices, which provide a promising alternative to a sustainable and stable IoT, where the energy collected from the environment is stored in systems of supercapacitors or ultracapacitors. Limited storage of collected energy and the unpredictability of collected energy lead to periodic behavior when the device is turned on and off. Measuring and understanding the current consumption and execution time of various tasks of IoT applications is crucial for the proper operation of these devices without batteries. In this article, we report a successfully designed and tested wireless LoRaWAN end sensor node without battery for IoT applications. The fundamental feature is the realized extremely low value of energy consumption that allows using supercapacitor and solar harvesting energy to power the microcontroller and sensors. We use a LTC3588 nano power energy harvester IC, solar panel and supercapacitor to power the wireless sensor node.","PeriodicalId":300010,"journal":{"name":"2020 28th National Conference with International Participation (TELECOM)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124455826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
