Finally an Ultrasonic sensor is used to detect if the parking slot is available or occupied and send the data to ESP8266 accordingly. See our Privacy Policy and User Agreement for details. Begin i2c 16x2 LCD and set cursor position at 0th row 0th column.

Two servo motors are used as entry and exit gate, so whenever the IR sensor detects a car, the servo motor automatically rotates from 45° to 140°, and after a delay, it will return to its initial position.         s3_occupied = true;
int slot1  = D3; Begin connection with Firebase with Host and Secret Key as credentials. PROJECT   digitalWrite(TRIG, HIGH);        // make trig pin high

If you already know using firebase with NodeMCU then you can move ahead else you should first learn to use Google Firebase Console with ESP8266 NodeMCU to get the host address and secret key. Connect to WiFi and wait for some time till it gets connected.

The IoT has enabled the possibility of Smart Cities with it’s over the internet control feature.         It will show the entry time and exit time for every slot.

#include        retries--;        myservos.write(OPEN_ANGLE);     }.     delay(2000); for (pos = 45; pos <= 140; pos += 1) {       // change servo position If I hadn't gotten lucky that day I'd be half a million pounds poorer now and my life would be a hell of a lot different.

For test and try, with some limitation, Adafruit IO is free to use. There are many lanes for car parking, so to park a car one has to look for the all lanes. Check all the ESP8266 based Project here. Now days finding parking in busy areas is very hard and there is no system to get the details of parking availability online. #include

Connect the Entry and Exit Servo Motor to the D5, D6 Pins of the NodeMCU. int  hh, mm, ss; It involves two IR sensor, two servo motors, one ultrasonic sensor and one 16x2 LCD. The Pins for I2C in the ESP8266 NodeMCU are D1 (SCL) and D2 (SDA).       Serial.println("Occupied2 "); We previously used Adafruit IO cloud in many IoT projects, follow the link to learn more.           //Serial.print(EntryTimeSlot1); That's a life changing amount of money.    delay(3000); Publish the variable data to the Adafruit IO feed. Then increase the count for entry gate and decrease the count for exit gate and publish the data to the Adafruit IO dashboard.        } String Available = "";                                                  //availability string Adafruit_MQTT_Publish EntrySlot2 = Adafruit_MQTT_Publish(&mqtt,MQTT_NAME "/f/EntrySlot2"); Automatic Smart Parking System using IoT Vasanth Vidyakar. int slot3 = D7;                 

You can download the NTP client and Adafruit MQTT libraries from the below links: Then include the Wi-Fi and Adafruit IO credentials that you copied from the Adafruit IO server.    } int countYes = 0; int slot2 = D6; Adafruit_MQTT_Client mqtt(&client, MQTT_SERV, MQTT_PORT, MQTT_NAME, MQTT_PASS); //Set up the feed you're subscribing to The best i could do was able to find sevo library for esp32 and not for esp8266.. i really hope that you help me this library. You can change your ad preferences anytime. ix Industrial 10 position connectors feature Cat6A 10GBASE-T performance and PoE capability.     } 6. Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. From your entry to the payment and exit all can be done automatically. To find these values follow the previous tutorial on Firebase. Adafruit IO dashboard also has two buttons to manually operate the entry and exit gate. CarsParked.publish(count)) {}, if (s1 == 1 && s1_occupied == false) {                             mqtt.disconnect(); zenebe January 19, 2019 at 7:18 am. Here we are using firebase as Iot database to get the parking availability data.

Here we are directly checking for a specific word in our subscribed feed, and if the word matches with our specified word, i.e., ‘ON,’ it will rotate the servo motor to open the gate.   Serial.println(WiFi.localIP());                                            //print local IP address        s1_occupied = false; This system can completely automate the car parking system. 7,348 views; 8 comments; 23 respects; This parking sensor with Arduino is an easy project.   myservo.attach(D4);      // servo pin to D6    if (entrysensor == 1) {                     // if high then count and send data String fireAvailable = ""; LiquidCrystal_I2C lcd(0x27, 16, 2);         //i2c display address 27 and 16x2 lcd display Jul 19, 2019     for (pos = 140; pos >= 45; pos -= 1) {        // change servo position Dr. Falah Hassn | Fatheya Refat     countYes++;                             //increment count Moreover, the proposed system collects the raw data locally and extracts features by applying data filtering and fusion techniques to reduce …   while ((ret = mqtt.connect()) != 0) // connect will return 0 for connected   if(s2 == 0 && s2_occupied == true) { With growing popularity of Smart Cities, there is always a demand for smart solutions for every domain. For this project, we created a total of nine feeds for exit gate, entry gate, slot 1 entry & exit, slot 2 entry & exit, and slot 3 entry & exit.   }.   Serial.println(); Then convert it to the ‘cm’.
  int carExit = digitalRead(carExited);              //read exit ir sensor
