Essay Example on Raspbian Operating System








Method Firstly set up raspberry pi with Raspbian operating system The operating system download on the official raspberry pi website Then the operating system burn to SD disc The disc is placed on the raspberry pi Then power is connected on the pi Then install Adafruit library on pi terminal Download putty software to connect laptop onto the pi and also install Xming software for using the laptop display as the pi display Now the raspberry pi connect to the local Wi-Fi network Use advanced IP scanner to find the ip address of pi Then using this ip address to connect the pi using the putty and xming software Then it connect the cayenne Iot server IOT dashboard Cayenne by my Devices is totally free online builder they do not yet make it paid services because they working on it to make more reliable and stable when they release stable version may we have to pay for this cloud service Currently in Raspberry pi version which has Lil bit bugs but not too worried about final version they will make it bugles online portal Feature of Cayenne My Device IOT Dashboard Remotely access Pi from Mobile and PC Reboot Shutdown Pi Remotely add sensors actuator extensions and design dashboard for Raspberry pi add widgets with drag and drop feature Remotely monitor live data from sensors and actuator Control sensors actuator with dashboard GPIO Best thing is that for you Automation Projects you can make the trigger and add the schedule Let's start how it is work with Raspberry pi Configuration of Cayenne Raspberry for Home Automation Cayenne is IOT based dashboard so you need hardware which can be connected to the internet for this purpose you need Raspberry Wi Fi or Ethernet Shield The important thing is how to configure Cayenne IOT dashboard for Raspberry pi I make this guide step by step to understand easily who not know much about IOT but want to learn Step 1 First of all you need a working internet connection then create a free account on Cayenne

When you added sensor and relays you need to configure each which you connected on Raspberry Pi on which pin Digital Analog See below images how I Figure Raspberry pi GPIO pins Diagram Configure you can also use invert logic in setting of any sensors actuators Invert Logic can be used to reverse the high low signal The most common use of this is with a LED if the button on the dashboard turns the light on when it should be turning it off clicking invert logic will reverse the signal to correct the problem Now added Trigger go to sensor settings and select trigger option Cayenne IOT dashboard also has a feature to schedule your sensors actuator and also I add a trigger for notifying when the Light on and off I can get notification via Email and SMS I can control and manage my project from Mobile app and PC 3 2 12 Smart home automation system This application of the module can be explained by an example Suppose the owner is expecting a guest at his house but he is not available there Now as the guests reach at his house the owner will receive a video call But now the owner can press digits other than 1 such as 3 for lights 4 for fan 5 for A C and so on or even can disable the security system

Similarly if the user or somebody leaves the house the user Will still receive a video call and this time he can switch off the appliances or can enable the security system again by pressing proper digits known to him Since the appliances are connected to mains supply through a relay they can be easily controlled using microcontroller 4 1 Result and Discussion Both the Raspberry Pi and the mobile application are senders and receivers of data This applies as both publish and subscribe at the same time to the same cayenne IOT server This allowed bi directional communication for data exchange Accordingly multiple use cases were implemented and studied for result analysis 4 1 1 Home appliance control The Light Fan and other home appliance are connected to the Raspberry Pi through the GPIO pins and embedded in the model were controlled through a mobile application developed with Ionic A Light tab was created in the application which has a button that toggles between ON and OFF when clicked The default value of the button shows the current status of the LED lights If the button shows the value OFF this means that the LEDs are currently turned off
