Five hack challenges and a brilliant idea

A major part of Europe’s biggest Internet of Things (IoT) conference Bosch Connected World (BCW) is the hackathon Bosch Connected Experience (BCX). This year, over 4,000 participants and more than 700 hackers met at STATION in Berlin to discover how IoT will change our lives. This time, creative ideas in five different hack challenges were in demand. For their concepts, the participating teams could use the Cross Domain Development Kit (XDK) and thus once again show what use cases are possible with XDK.

Stop water pollution – the winning idea of the #BCX18 connected life hack challenge

The hackathon Bosch ConnectedExperience 2018 challenged the participants in five different categories: Connected Mobility Services, Autonomous Driving, Manufacturing 4.0, Connected Life as well as Supply Chain & Logistics 4.0. In the connected life hack challenge, eleven out of the 22 teams competing against each other used the Cross Domain Development Kit. In case of any questions or minor obstacles, hack coaches from Bosch Connected Devices and Solutions assisted the teams. In the end, every team pitched their idea to a jury who then announced the winner.

The winning team’s idea was to develop a sensor system that fights water pollution in India. To introduce their idea and start the pitch, they showed dramatic pictures of the water pollution. There are already projects that should help to reduce the pollution with fixed positions sensors, which detect the water quality of the river at a certain point. However, the idea has limitations, because the initiators did not get any clue where the pollution root cause occured. They only got vague information that it is somewhere upstream.

Sensors must be there where the waste is

E-mute, the winning team, had a simple yet very creative idea to solve this issue: pollution sensors should flow down the river so that the sensor is located where the waste is. As a result, the sensor controls water quality during the journey down the river. If it detects a significant pollution, the exact position of the pollution is tracked via its Global Navigation Satellite System (GNSS) and transmitted to the back end via Low Power Wide Area Network (LPWAN), in this case LoRa. The conceptual E-Mute device combined two existing sensors: Traci, which is able to report its exact position via GNSS and the Cross Domain Development Kit (XDK) from Bosch to further extend the water quality sensors.


With this idea, the winning team developed an answer to the question of how to stop water pollution in India, especially in the Ganges River. This problem is not a local problem in India - this is a global issue. E-Mute set up a great concept within only two hack days and was able to convince the jury of BCX.
