Story

A free we tool

The Challenge | Live Smart

Evaluate environmental, social, and economic data to design tools and plan blueprints for smart and connected rural and urban settlements.

The problem

Distance to amenities is a major problem faced by people who relocate every once in a while, like Government Employees and Job Seekers.

Unfamiliar weather might cause health problems and other allergic reactions that may cause discomfort.

No easy way existing to find the perfect suitable Living Space.

The solution

A free web tool where users can find their suitable place with the help of suitable data from NASA, Google and IoT devices.

1. Live in a healthy Environment.

2. Be equidistant from nearby amenities.

Living Space

Moving Somewhere New? Want to know the climate of a location? looking for a place with School, Hospital, ATM or any other public amenities nearby and within immediate reach? Use LIVING SPACE APP to find that perfect location that you have been searching for all along.

beta showcase

just search or drop a pin on the map of any desire location or an area and a pop up card with several facets will appear, which includes climatic and weather forecasts, predicaments along with the milestone markings to the nearest amenities.

The card also features a drop down menu which further elaborates about the place and will include Weather details from the local weather station setup as a crowd-sourcing initiative at various locations around the world. The data from pool of weather stations will be stored in our database and could be accessed through API.

on the side tab there is check list of the facilities which you may priorities to be nearest to your location.

check those parameters and hit 'Search'. The app will then compute and triangulate a location closest to all these amenities and will suggest locations which meets the all the criterion by a circular marker spanning 5 mile radius. (the distance can be passed out as an additional parameter)

Resources Used :

Google Maps API

Open Weather Map API

Breezometer Air Quality API

Google Firebase Database

Arduino IDE

Programming Languages Used : HTML, CSS, JS, C++, ASP.NET

Hardware Used for mini weather station :NodeMCU ESP8266, DHT11/22 sensor, BMP180 sensor*, UV sensor, Rain sensor, anemometer*, Dust sensor*, CO gas sensor*.

(* indicates sensors yet to be implemented)

Future integration/scope :

Disaster aversion methods

Pets/Animal habitual compatibility

Installment of weather monitoring stations across prime locations around the globe.

API access to Living Space database

This app was developed as a part of NASA SpaceApps Challenge 2017 which is a NASA incubator innovation program.

web tool is still under developmental phase but codes for mini weather station is available.

will keep update on any developments... peace ✌️.
