IoT Sensor Data Acquisition and Storage System Using Raspberry Pi and Apache Cassandra
Katalin Ferencz, József Domokos · 2018
In this paper, we introduce an alternative solution to the many existing IoT data acquisition and storage systems. We present a self-designed and developed prototype electronic circuit extension for Raspberry Pi development board used for collecting sensor data. There is also presented a Pi4Java API based Java application used for sensor data collection and storage. We set up an Apache Cassandra database cluster, to stores large amounts of sensor data on low-cost servers, providing high availability. In addition, a web application is also presented, that allows different data visualization operations to be performed on the stored data. The presented system is a full IoT data acquisition, storage and visualization solution.
