Weather Logger

Weather Logger using Raspberry Pi – The main aim of this paper is to propose a system that gives information about weather status in any place in the world. It gives current weather and Forecasted weather also by using the API of weather cloud without using any sensor. In past days the weather can be monitored by using sensors like Temperature sensor, Humidity sensor, rain sensor, and anemometer which determines the wind speed those sensors are interfaced with any Controller, and values are sent through GSM. Nowadays we use Raspberry Pi which is a single board computer it performs all the actions performed by the computer. By using the URL of any weather cloud, we can extract the weather status of any place in the world and it is saved as a file by using Speaker we can hear voice output.


INTRODUCTION

Weather is a very important parameter employed in all sectors sky communication like Airplane and rocket is purely weather dependent. Weather forecasting is a very big issue is now a day’s geological scientists have forecasted the weather and say what happens in the upcoming days. And it becomes very helpful to blind people and elderly people traveling from one place to another. With the help of Some sensors in the olden days. But in now a day’s by using the weather cloud we can get whole the information about the weather status by using Cloud API without using sensors because sensor values are not some much accurate. It is very useful in farming activities to forecast details about Rain.


EXISTING SYSTEM

In the Existing system, we are using a Sensor for getting weather monitoring all the sensors are interfaced with one micro-controller the microcontroller decodes that information sends to one cloud or displayed it as a value in LCD or any other display.

  • Humidity (DHT11) – Moisture
  • Temperature (LM35) – heat
  • ESP8266? – Wi-Fi module

These all values are sent to the IoT cloud as a parameter we monitor anywhere in the world


PROPOSED SYSTEM

In the existing system, the whole system is based on sensor values only but in practical sensors, values are not much accurate so we go for an alternate option to extract the forecasted and current values from the API of the weather cloud. Many of the weather clouds do not provide free API services for direct extraction of values if forecasted and current weather information. By using the URL of that weather cloud, we can extract the information using Python. And we get voice output by using the E speak library in python.

BLOCK DIAGRAM DESCRIPTION

The overall system consists of a Raspberry Pi module which acts as the heart of the whole system, whether cloud or speaker which is connected to the internet using inbuilt wi-fi. Which also has a monitor connected to the Raspberry Pi using a VGA to HDMI converter.


PROJECT DESCRIPTION

We took input from the weather cloud using API if that Cloud is extracted using Python programming Text values get converted to voice output by using the Espeak library which can get through Speakers. This text-to-speech conversion can be done through the python library function. In this system not only current weather but we can also able to see the upcoming weather conditions with intimation if there is any possibility of worst weather conditions like a heavy thunderstorm, flood possibilities, heavy rain, etc. all over the world. So that precautions can be made before themselves. This whole system is developed using python programming.


HARDWARE REQUIREMENT

  • Raspberry Pi
  • SD card
  • Speaker
  • Power supply

SOFTWARE REQUIREMENT

  • Raspbian Jessie
  • Weather cloud API
  • Espeak
  • Python

CONCLUSION

This whole setup is made as a prototype it gives an audio output of a weather status report through the speaker. Which place we mentioned in a program will give voice output accordingly. We can get both forecasted value and current weather updates by which place is mentioned by us. This system is very helpful for Blind people, and elderly people and is mainly used for agricultural purposes. This is a test among various test cases and we got some more attractive results which help elderly and blind People.
