Our broad technological background allows us to combine a number of cutting edge technologies in our solutions. From embedded hardware to Big Data Analytics using Apache Spark with mongoDB and Apache HBASE as well as bigdata/smartcity open source projects like sentilo.io, sitewhere.org and thingsboard.org.
A side project of ours is the development of our own open source solid state, maintenance free hardware weather station, adopting a number of innovative approaches in environmental sensing as well as in communications using LoRaWAN wireless technology. Our goal is to create a low-cost, solid state weather sensor that can be deployed in large scale grid topology in order to provide real-time weather radar-like services as well as a plethora of other weather analytics which can be build on top.
To achieve this on a global scale, we are part of TheThingsNetwork deploying LoRaWAN gateways in our region, being part of the largest global LoRaWAN network (4k active gateways). We were the firs to deploy such infrastructure in Greece (Athens TTN initiators) and the first to utilize it commercial in Athens airport for environmental monitoring.
We recently also won the 2018 hackaday design challenge prize with our unique weather station, find out more at https://hackaday.com/2018/05/17/the-solid-state-weather-station/
