- 2. Weather Monitoring System Using Raspberry Pi
- 3. Introduction Many things affect the weather. And weather also have affect on most of living as well as non- living things. At Weather station study of different environmental parameters using some instruments and equipment's has been done. So to meet the goal of weather monitoring we have designed IoT based real-time, low-cost, portable and high speed weather station using Raspberry Pi. At our weather station we are measuring some environmental parameters like temperature& humidity. IoT means Internet of Things. It provides inter-networking of physical devices, buildings, vehicles and other components like sensors and actuators. By giving network connectivity to systems embedded with electronics, software, sensors and actuators; these objects are able to collect and exchange data. By using IoT objects to be sensed or controlled remotely through existing network. It gives opportunity to connect physical world with computer-based systems.

- 5. Raspberry PI RASPBERRY PI platform is most used after ARDUINO. Although overall applications ofPI are less it is most preferred when developing advanced applications. Also the RASPBERRY PI is an open source platform where one can get a lot of related information so you can customize the system depending on the need.
- 6. Raspberry PI Here are few examples where RASPBERRY PI 3 is chosen over other microcontrollers and development boards: 1. Where the system processing is huge. Most ARDUINO boards all have clock speed of less than 100MHz, so they can perform functions limited to their capabilities. They cannot process high end programs for applications like Weather Station, Cloud server, gaming console etc. With 1.2GHz clock speed and 1 GB RAM RASPBERRY PI can perform all those advanced functions. 2. Where wireless connectivity is needed RASPBERRY PI 3 has wireless LAN and Bluetooth facility by which you can setup WIFI HOTSPOT for internet connectivity. For Internet of Things this feature is best suited. 3. RASPBERRY PI had dedicated port for connecting touch LCD display which is a feature that completely omits the need of monitor.
- 9. DHT11 (Humidity & Temperature) Sensor The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). Its fairly simple to use, but requires careful timing to grab data.
- 10. Breadboard A breadboard is a very useful device for prototyping circuits. It allows you to easily plug in and remove components and so if there are going to be many changes or if you just want to make a circuit quickly, it will be much quicker than soldering up your circuit.
- 11. Jumper Wires Jumper wires are simply wires that have connector pins at each end, allowing them to be used to connect two points to each other without soldering. Jumper wires are typically used with breadboards and other prototyping tools in order to make it easy to change a circuit as needed.

- 13. 1. Download the Required Software and Files. i. Download Win32disk imagers. ii. SD Card Formatter. 2. Format SD Card and Plug in through Card Reader. 3. Write the Operating System on the SD Card : i. Open win32 disk Imager ii. Browse the .img file of Raspbian OS. iii. Click on open then click on write (Note: if any warning Popup then ignore those, by clickingOk) 4. After Completing Write process then Eject SD Card, Now OS is Installed in Memory Card. Process of Installing Raspbian OS
- 15. 1. Connect Raspberry Pi in Monitor through HDMI Cable. 2. Then Connect Raspberry Pi using Data Cable with your PC. (*Note:- Raspberry Pi and PC are connected in Same Network) 3. In Raspbian OS open Terminal and Open Terminal (CMD) and type ifconfig press Enter. 4. Then See IP Address, Subnet Masketc. How to Check Raspberry Pi IPAddress
- 16. Ifconfig Windows
- 17. VNC Viewer • In computing, Virtual Network Computing (VNC) is a graphical desktop-sharing system that uses the Remote Frame Buffer protocol (RFB) to remotely control another computer. • VNC is platform-independent – there are clients and servers for many GUI-based operating systems
- 19. Connectivity
- 20. Coding Open Python IDLE then New and Start Programming :-
- 22. Output in Cloud (ThingSpeak)
- 23. ThingSpeak • ThingSpeak is an IoT analytics platform service that allows you to aggregate, visualize and analyze live data streams in the cloud. • ThingSpeak provides instant visualizations of data posted by your devices to ThingSpeak. With the ability to execute MATLAB code in ThingSpeak you can perform online analysis and processing of the data as it comes in. • ThingSpeak is often used for prototyping and proof of concept IoT systems that require analytics.
- 24. CONCLUSION • This IoT based system gives real-time monitoring of environmental parameters. This system monitors temperature & humidity. Data can be seen from anywhere in the world. By using this system the client can continuously monitor different environmental parameters without any interaction with additional server. • Raspberry Pi itself acts as a server. This is efficiently carried out by Raspbian operating system. This weather monitoring system is designed using Raspberry pi is having low cost, small size, low power consumption, fast data transfer, good performance and remote monitoring. This system has some limitations, it do not have built-in Wi-Fi and built-in Real Time Clock.
