today i am here with new project
our project title name is IOT Based weather monitoring system using raspberry pi
this project is used for real time monitoring
for different environmental parameter using iot
IOT is nothing but connecting physical objects to the internet
and enabling exchange of data
in a more secure way
so here in this project
the data from all sensors will act as a input
and sent to the web server for online monitoring purpose
so let us move into detailed description of our project
Here you can see this is the block diagram
power supply is give here
temperature sensor,humidity sensor and pressure sensors are give as input to the raspberry pi
LCD is used here to display the messages
and ethernet or wifi is used to connect to the webserver
This is the hardware section
here you can  see raspberry pi
why i have choosen only raspberry pi rather than other boards
It reduces the complexity of hardware components
because it has on board audio jack,video jack,SD card slot
and through this micro USB port
we are giving power supply and general purpose input output pins
and Ethernet port which is used to give internet connection
to the system via LAN
Here i have connected LAN and here USB ports
Here you can see this is the pressure sensor
and this is temperature and humidity sensor
it has vcc,data and ground three pins
and this pressure sensor has SCL,SDA VCC and ground pins
so these are connected to general purpose input output pins
and this is LCD it is used for system monitoring purpose to display the messages
okay let us see the output on lcd
you can see here humidity level in showing 61%
let us observe the changes in the humidity level
now you can observe it went to 72%
Here temperature will be displayed on degree celsius
humidity in percentage,pressure in hecto pascal units
okay let us see the output in think speak web server
and this is the iot platform which is open source
in this webpage we can see the weather conditions
through this graphical view
so here we have three fields temperature
 humidity and pressure
in this temperature field we can observe temperature levels and humidity levels
and here pressure levels will be updated 
through  the sensors
so from this webpage we will have up to date real time information
of weather conditions
At weather stations many applications were implemented to know the status
it will monitor the weather and make that information visible anywhere in the world
It is connected easily and globally accesible
it provides efficient and low cost solution for the weather monitoring system
and this project gives real time monitoring
of environmental conditions as long as it is connected to the internet
it will be uploading the real time data
This project is very helpful for the farmers
as well as at the places like valconoes,rain forests etc
and it is quite difficult for a person
to stay for a longer time at such places
and if a person want to know the weather 
conditions over a particular place
he can just have access this website to know the status
and this is about our project
