Abstract

U ovom radu objašnjeni su osnovni mehanizmi povezivanja mikrokontrolera sa
SAP HANA bazom podataka na SAP Cloud Platformi. Pristup je podijeljen u faze
prikupljanja podataka pomoću mikrokontrolera, prijenosa podataka na SAP i prikaza podataka.
Prikupljanje podataka izvedeno je pomoću uređaja Adafruit Feather Huzzah, i senzora topline i vlažnosti zraka DHT22. Prijenos podataka temelji se na MQTT protokolu koji je detaljno objašnjen, kao i pozadina prihvata podataka sa strane SAP-a. U
svrhu prikaza podataka izrađena je SAP Fiori aplikacija na SAP-u. Cijeli postupak je potkrijepljen implementacijskim materijalom i daje čitatelju dobre smjernice kako rekreirati zadani scenarij.

Abstract (english)

This paper describes key concepts of connecting microcontroller with SAP HANA
database running on SAP Cloud Platform. The process is divided into three phases:
gathering the data with microcontroller, transfer of data to SAP and also displaying the
data.
Gathering data was achieved with Adafruit Feather Huzzah microcontroller, along
with temperature and humidity sensor DHT22. Data transfer is based on MQTT protocol that is thoroughly explained, aswell as the mechanism of acquiring data from SAP
side. For the purpose of displaying the data simple SAP Fiori application is developed.
The whole procedure is backed with implementation examples and gives a reader
intuitive guidelines on how to reproduce the given scenario.
