Smartphone Weather Data Collection System

The Development of a Weather Data Collection System using Smartphone

 

 

What Problem does this research project aim to solve:

 

The penetration rate of smartphones in developing countries is the last five years is phenomenon. Further, the sophistication of smartphones at affordable price is on the increase. Interestingly, more and more smartphones are equipped with weather sensors eg temperature, pressure, etc. In Sub-Sahara Africa, natural disasters and dwindling agriculture fortunes are becoming intractable socio-economics issues. Due to the impact of climate changes on agriculture and weather, it is imperative to devise a cost-effective approach to collect multiple weather data per unit square area     

 

The research goals and objectives:

 

The research seeks to develop a model to collect weather data using smartphones. The smartphones are volunteered  by the owners to collect weather data periodic, transmitted via user’s network to cloud facility for calibration, consolidation and archiving.

 

The project contributions include the following:

  1. The weather data distributed sensing technique
  2. The weather data calibration technique
  3. The business model

 

Abstract:

From time immemorial, humanity has always made efforts to understand and predict weather. Science has created several instruments to study our environments.  Modern science has helped to create very small and intelligent devices for data collection at small scale, and high processing capability  computers for the processing of such data even at real-time.

The geography of the earth changes from country to country, the geographic conditions are favorable in certain countries or continents more than others. Climate change and its impact on human existence on the earth is the motivation for this study. We need to collect more data with close ranges to be able to obtain a better understanding and better forecasting. Developed economies have been able to develop reliable climate data acquisition systems  using satellites, radars, and several ground weather stations. But, developing economies are unable to match up due to lean budgetary allocation.

However, in the last two decades,  smartphones have increasingly permeated the communities and societies in developed economies. These have become increasingly intelligent, user-friendly and capacitated. One of the principal components inbuilt in smartphones are the sensors which are able to sense physical phenomenon. Many of these sensors include humidity sensor, ambient temperature sensor, barometric sensors. Smartphones popularity everywhere  and mobility make it as good device for atmospheric data collection with little cost or no cost.

There are examples of similar technologies eg. pressureNet, Accuweather, and Open signal. These technologies are internet dependent.  The issue of internet connectivity makes these technologies unsuitable for the developing economies because per capita internet access and bandwidth is still very low so, there is a need to develop a smartphone and GSM weather data collection system

The Structure of proposed system

The atmospherics variable sensors are integrated into smartphone to provide the specific weather data. The data is periodically calibrated and aggregated into a server.

The system which will be implemented in two parts,  the client apps on the smartphone, and the server apps on telco or service provider  sider. The following functionality will be provided:

For the smartphone

  • data calibration
  • collect and send the data like SMS through GSM, therefor be real-time
  • weather forecasting

For the server

  • Collect the data from the weather stations
  • Process the calibration data and transmission of the calibration data
  • Send the data to the government/business agency for processing, forecasting and dissemination.  

The recap on the system is shown in the following picture.

  • 2 and 3, 2 and 4: Internet connection for high speed connection to send and receive  data.
  • 2 and 3, 2 and 4: Internet connection for high speed connection to send and receive  data.
  • 1 and 2: GSM connection, if  Internet is not available, it will send and receive the data via GSM/SMS.
