Space Apps Challenge 2017

Introduction

Ourteam has decided to focus our research on the water problem,specifically problems brought by floods.

Themushroom sonar was born from the idea of being able to provide aninformation service in real time and predictive, on rivers, lakes andother water sources, which, paired with data from the national andglobal weather forecast - Nasa station-, will allow us to predictpossible floods and their consequences in critical areas.

Accordingto the population density and other factors such as industries,hospitals and police stations available in the area, we havedeveloped a predictive map, which distinguishes between areas of low,medium and high risk.

Sonar

Allour measurements are made by special hardware which has been adaptedto our necessities, called Sonar. This is made up of differentsensors:

• a temperature sensor, which allows us to detect thermal changes inthe water and collect data about possible changes in the ecosystem.
• an oximeter, which measures the level of oxygen present in thewater, and allows us to know about changes in the aquaticecosystem’s structure.
• a Ph module, which measures the levels of acid in the water andallows us to detect changes in the deep currents and/or movements ofthe sediment.
• an echo sounder, which measures the distance between the surface andbottom of the lake.
• a GPRS module, which allows us to connect to an internet server andalso the location - HTTP protocol.
• an Arduino Mega, which is responsible for connecting all thesensors and peripherals and is in charge of requesting the datagathering and its transmission to the server.

Alldata gathered is sent to our server, where it’s processed andpaired with the information obtained from weather reports.

Software

Oncein the server, our web app takes the data and the weather reports andallows us to obtain information in real time about the environmentalstate and variations of rivers and their affluents, and thereforeknow the areas in danger in the case of an overflow, providinginformation about the number of people that may be affected by it.

Withall this data, a report is made which, depending on the populationdensity, will be disseminated with a considerable amount of time; inthe case of highly populated areas, the government will be informed;and in the case of rural areas, the population will be directlyinformed, so as to organise an action plan.
