IoT - RapsberryPi Weather Station

The general objective of the project is to use the Raspberry Pi combined with sensors
to send information to a web site that stores the statistics (Carriots).
Separately build a phone App that allows you to access that stored information in any time.

IoT Weather Station 01

IoT Weather Station 02

It was actually useful: the 2017 Winter was particularly cold in Dublin with heavy snow
and the flat where I was living was really cold when the heater was down. So I could
have measurements of the room's temperature being made every 15 minutes and I could
see that it was actually really cold inside and not only me whining.
Moreover on the same table I would have measuerements of external temperature from OpenWeather
so I could constrast my room's temparature with the actual weather conditions.

The Technologies involved were:

1: Raspberry Pi
2: Pi's GPIOs and sensors
(Temperature, Humidity and Presence)
3: Carriots Site
5: Python
6: Linux's Crontab
7: MIT Inventor
8: Android Phone

Python to get measurements and send them to Carriots.

Python Query piece of Code

Also store the data locally in a CSV file.

Excel Data with measurements

An Android phone app was designer using MIT's Inventor.
