Sobre este projeto

Como tudo funciona?

PASSO 1:codificando o Octopod principal

• Incluindo as bibliotecas:

  #include  // Incluir Biblioteca Blynk # include  // Incluir Biblioteca Blynk # include  // Incluir biblioteca do sensor DHT # define BLYNK_PRINT Serial  

  // Você deve obter o Auth Token no Blynk App.// Vá para as configurações do projeto (ícone de noz) .char auth [] ="Your Auth Key"; // Your WiFi credentials.// Set senha para "" for open networks.char ssid [] ="Your WiFi SSID"; char pass [] ="Your WiFi Pass";  

• Definição de pinos e inteiros:

  #define DHTPIN 2 // Qual pino digital de temperatura e sensor de umidade está conectado # define soloPin 4 // Qual pino digital de sensor de umidade do solo está conectado # define gasPin A0 // Qual pino analógico de sensor de gás está conectado to # define pirPin 12 // Qual pino digital do sensor de umidade do solo está conectado ao int pirValue; // Lugar para armazenar read PIR Valueint soloValue; // Lugar para armazenar leia Soil Moisture Valueint PIRpinValue; // Local para armazenar o valor enviado pelo Blynk App Pin V0int SOILpinValue; // Local para armazenar o valor enviado pelo Blynk App Pin V1  

• BLYNK_WRITE ():

  BLYNK_WRITE (V0) // O pino VO do aplicativo Blynk informa se a detecção de movimento está ATIVADA {PIRpinValue =param.asInt (); } BLYNK_WRITE (V1) // pino V1 do aplicativo Blynk informa se a umidade do solo está ATIVADA {SOILpinValue =param.asInt (); }  

• void sendSensor ():

  void sendSensor () {int h =dht.readHumidity (); int t =dht.readTemperature (); // ou dht.readTemperature (true) para Fahrenheit if (isnan (h) || isnan (t)) {Serial.println ("Falha ao ler do sensor DHT!"); // para verificar se o sensor não está enviando nenhum valor falso return; } // Você pode enviar qualquer valor a qualquer momento. // Por favor, não envie mais de 10 valores por segundo. Blynk.virtualWrite (V5, h); // envia umidade para o pino V5 Blynk.virtualWrite (V6, t); // envia temperatura para o pino V7}  

• void getPirValue () &void getSoilValue ():

  void getPirValue (void) {pirValue =digitalRead (pirPin); if (pirValue) // pino digital de PIR fornece alto valor na detecção humana {Serial.println ("Movimento detectado"); Blynk.notify ("Movimento detectado"); }} void getSoilValue (void) {soloValue =digitalRead (soloPin); if (soloValue ==HIGH) // pino digital do sensor de solo fornece valor baixo quando a umidade é menor {Serial.println ("Plantas aquáticas"); Blynk.notify ("Plantas aquáticas"); }}  

• configuração vazia ():

  void setup () {// Console de depuração Serial.begin (9600); Blynk.begin (auth, ssid, pass); // Você também pode especificar server://Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442); //Blynk.begin(auth, ssid, pass, IPAddress (192,168,1,100), 8442); dht.begin (); // Começa a leitura do DHT Blynk.tweet ("OCTOPOD IS ONLINE!"); // Tweating em seu Twitter Handle que você projeta está online pinMode (pirPin, INPUT); // Definir que Pir Pin deve receber apenas Input pinMode (soloPin, INPUT); // Definir que o pino do sensor de solo deve receber apenas entrada // Configurar uma função a ser chamada a cada segundo timer.setInterval (1000L, sendSensor);}  

• void loop ():

  void loop () {Blynk.run (); timer.run (); if (PIRpinValue ==HIGH) // O pino VO do aplicativo Blynk informa se a detecção de movimento está ATIVADA {getPirValue (); } if (SOILpinValue ==HIGH) // pino V1 do aplicativo Blynk informa se a umidade do solo está ATIVADA {getSoilValue (); }}  

ETAPA 2:codificando o RFID Smart Lock

• Vá para Sketch → Incluir biblioteca → Gerenciar biblioteca → Digite na barra de pesquisa MFRC522 e instale a biblioteca. Em seguida, vá em Arquivo → Exemplos → Bibliotecas personalizadas → MFRC522 → dumpInfo Sketch. No início você pode ler como conectar os pinos (Ou consulte a imagem). Em seguida, execute o código e abra o monitor serial e coloque seu cartão RFID na frente do Módulo MFRC522 e aguarde 5 segundos. Em seguida, observe o UID do cartão de maneira semelhante, observe os UIDs de seus outros cartões e chaveiros.

• Em seguida, baixe o código de sua preferência. Abra o código e vá para esta linha. Aqui, no lugar desses Xs, adicione o UID do cartão que deseja usar para abrir a porta. Agora que você está pronto, basta fazer upload do código.

  if (content.substring (1) =="XX XX XX XX") {}

• STEP 4:Setting Up Python Program

$ source ~/.profile $ workon cv  

$ cd Smart-Security-Camera  

$ pip install -r requirements.txt

STEP 4:Blynk App Interface Setup

• Downloading the Blynk App is the first obvious step. Download it from App Store or Google Play Store. Sign Up or Login in the app to get started.

• Click on New Project to create a new project. Name it whatever you like. In devices Choose NodeMCU. In connection type choose WiFi and click on Create.

• Now you will get a Auth key on your Email. Make sure to copy that and add that to your code.

• Now click on the + sign to add widgets. You may need to buy some energy!

• Now add three Gauge's. Click on of the Gauge's, name it Temperature. Choose a color of you choice for this gauge. In the pin choose Virtual Pin V6. Set the range from 0 to 50 °C ( not sure for °F), make the label °C/ °F and keep the reading rate to Push.

• Repeat this for other two Gauges using data as shown in the pictures.

• Now, add a zeRGBa and set R to digital Pin GP15, B to GP3 and B to GP1.

• Now add 4 Buttons, change there colors accordingly. Set them as shown in the pictures.

• Add a SuperChart, add 3 data streams Temperature, Humidity and gas, set there colors, there pins, Range and Suffix.

• Now, add tabs. Go to the second tab and add Twitter, Notifications, Email and Eventor. In Twitter add you twitter username and password. In Notifications, Switch on Notify when hardware goes off. In Email, set your Email address. In Eventor you can set many triggers, see the picture for the triggers that I have set up.

• You are done. now click on the play button to use the interface that you have created. You can change the interface as you like. It is really simple and fun process!

STEP 5:Making Octopod Structure

• Take your cardboard and draw a rectangle of 9 cm x 9.5 cm (You can change the dimensions as per your convince). Now, joining end to end draw 4 of theses similar rectangles (8 if your cardboard is long enough).

• Now make partial cuts (somewhat like paper creases) in between these rectangles and cut out this whole long piece. Repeat this process until you have 4 of these long pieces.

• Now, using a D draw a 135° and cut it out as shown in the images. Make 16 of these same angles.

• Using Glue gun glue these angles in between the small pieces. Repeat this for all the joints.

• Now using glue gun join 2 of these open structures to make a closed structure (somewhat octagon) .

• Now glue the other two open structure perpendicularly, making a 3-D shape.

• Now Cut 4 More pieces of of 9 x 9.5 cm and glue them in between all the empty spaces.

• Now you will be left with only 8 open triangles. Using Acrylic Butter paper cut 8 triangles, which will fit on these open areas, but don't glue them now.

STEP 6:Making Door Lock Enclosure

STEP 7:Assembling the Octopod

• We have connected the nodeMCU to a large size Solderless Breadboard. We have also connected Breadboard power supply on the breadboard. NodeMCU, all the sensors, LED's and other components are powered by the power supply.

• Following are the sensor connections:DHT11 → D4 / GP2 MQ2 → A0 / adc00 Soil Moisture Sensor → D2 / GP4 PIR → D6 / GP1 RGB R → D8 / GP15, G → Rx / GP3, B → Tx / GP1 RelayLn1 → D0 / GP16, Ln2 → D5 / GP14 Make the following connections.

• For powering this you can use Power Bank or a Wall Adapter, which will be connected to the breadboard Power supply.

• Now, take your Raspberry Pi along with the Raspberry Pi Camera. Make a small hole in one of the walls of the cardboard and glue or tape your Raspberry Camera.

STEP 8:Assembling the Door Lock
