IOT Greenhouse project part 2






here you can see how hardware has been connected and how Networking part is happpening 


Here our main goals were Light and watering control,Temperature and humidity Controlling , Image processing to monitor leaves of the and infections , Automatic management and and remote monitoring. Client can have latest status of the greenhouse . Here we have used MQTT protocol because it is lightweight messaging protocol . Here each sensor has topic. As an example humidity sensor has topic greenhouse/1/hum other sensors also have. So here Arduino UNO + WIFI shield is acting as a MQTT client and publish this sensor data to the related topics . Then in Raspberry PI there is MQTT server and from the PI data will be put into a Graphical user interface .So any user with proper authentication can connect to the IP of the raspberry and get these data.

So i think you have some idea about the hardware part. Next  we are planning to do the Controlling part and Image processing part to the Greenhouse.

IOT Greenhouse project part 1

How to build Simple IOT Greenhouse (Part 1) This this project we are going to control a stable environment to the plant inside the greenhouse.  With using mqtt protocols and latest IOT suff. And also we can monitor plant conditions using digital image processing. So let's start this step by step. Part 1 is all about setting up the sensors and hardware part. So what do you need to this project ? Components 1.) Arduino Uno with wifi shield 2.) Raspberry PI 2 Board and wifi adapter. 3.) DHT 21 (AM2301) Temperature and humidity sensor 4.) Soil Moisture Sensor 5.) Light intensity sensor 6.) Water pump 7.) Raspberry PI Camera or web cam for image processing 8.) 16 in to 4 LCD display Don't be scared i'm going to explain bit by bit how to build this system. First of all you have to design the hardware part. plug the sensor to the arduino in correct way. Simple Arduino Code to get sensor data and display here this code is without the arduino w

How to fix FirebaseApp with name [DEFAULT] doesn't exist issue with flutter This is a very common issue when we try to google authenticate our app with flutter. Please check the following are done in your app. Updated the android build.gradle file Updated the android\app build.gradle file Added dependency to pubspec.yaml Placed the google-services.json file Check Updated the android build.gradle file Add the following line to the android/build.gradle file please add the following line to that file. classpath 'com.google.gms:google-services:4.3.2' // Google Services plugin Check Updated the android\app build.gradle file Add following line to the following location apply plugin : 'com.google.gms.google-services' Check Added dependency to pubspec.yaml firebase_auth : ^0.14.0+5 google_sign_in : ^4.0.7 Placed the google-services.json file make sure you have added google-services.json from the firebase

Node.js how to work with Serial ports and display data on a beautiful frontend using Highcharts API Part 2

Image
Now you have some basic idea of the technologies we are using here. So let's get our hands dirty. First, we have to set up the Node js libraries correctly to handle the serial data and open a WebSocket. So simple what we here going to do is getting data from USB and put them into a GUI to visualize our data nicely. So for this tutorial, I'm going to use Arduino as my data source. Piratically this will be your sensor or devices which you are using. Here http://www.highcharts.com/  Highcharts makes it easy for developers to set up interactive charts in their web pages. This has good community support and this is best for our works. 1. First step clone this repository https://github.com/akilawickey/nodejs-serial-frontend/tree/master Here is the Arduino sketch sample.ino which I'm using to emulate data which you can find inside the repository 1: /* 2: * This code will emulate USB data 3: * 4: * 5: */ 6: // the setup function run
