IoT based Coffee quality monitoring and processing system in Rwanda

Coffee is Rwanda's main source of income, thus improving processing and monitoring has a large potential economical impact, we are introducing low-cost sensor Technology, by utilizing embedded system to monitor coffee washing station processing method and store centers, the system will be reporting the status of PH, moisture, temperature and humidity as basic information to keep the standard quality of coffee, continually monitor these stages and alerting right time to move from one stage to another to meet requirement of export market. In this paper we describe the background of coffee quality major issues through processing and monitoring, our proposed e-Kawa solution and preliminary experimental results obtained in lab testing. We believe that similar technologies could be beneficent in local coffee processing anywhere else with similar conditions.
