It indicates that the parking space is vacant And the distance between that cell and becoming empty is 5m + The car is reversing, and the distance is between 5m and 2.5m The yellow light will appear immediately, and the instruction will be to proceed deeper + When the car is less than 2.5m and larger than or equal to 1m, the red light illuminates and the message "Parking" appears + Finally, if the automobile backs into the parking lot for more than 1m, the buzzer will ring and the words warning will appear on the screen Here are some images of the gadget as it was developed in Tinkercad It aids us in determining if the circuit and equipment will operate consistently when put to use 7|Page Figure 1: Project demo on Tinkercad 1.1.2 Members and roles We have members include: Students ID Name Role GCS200763 GCS200252 GCS18268 GCS200454 Team leader Team member Team member Team member Ha Quang Thong Huynh Tran Anh Khoa Hoang Thanh Khoi Vo Hoang Hien Figure 2: Team working 8|Page 1.1.3 Project Plan Everyone on our team worked on the project for a total of four weeks • • • The first and second week: we came together to agree on the idea and contribute the code together The third week: we came up with the idea of building the model and assembling the components together Fourth week: We fix the bugs encountered by the device, test them one last time and write the report Nominate Designated participants Completion schedule Discuss and agree on the topic for the project All members Fully List of sensors and operating procedures Khoi, Thong Fully Coding Thong, Khoi Fully Assemble components build models All members Fully Testing the model Hien, Khoi Fully Create and modify a project demo video Khoa Fully Conduct a survey to gather comments Khoa Fully Write report All members Fully 9|Page 1.2 Project model design Figure 3: Smart Parking Sensor System 1.3 List of devices for the project 1.3.1 Arduino Uno R3 Figure 4: Arduino Uno R3 10 | P a g e Technical specifications − − − − − − − − − − − − − − Microcontroller: Microchip ATmega328P Operating Voltage: Volts Input Voltage: to 20 Volts Digital I/O Pins: 14 (of which provide PWM output) Analog Input Pins: DC Current per I/O Pin: 20 mA DC Current for 3.3V Pin: 50 mA Flash Memory: 32 KB of which 0.5 KB used by bootloader SRAM: KB EEPROM: KB Clock Speed: 16 MHz Length: 68.6 mm Width: 53.4 mm Weight: 25 g 1.3.2 LCD with I2C Figure 5: Display with I2C Technical specifications • Parameter: Value • Screen Type: Dual colour LCD • Screen Resolution: 128*64 Pixels • Screen Active Area (L*W): 47.1*26.5mm • Individual Pixel Size: 0.33*0.33mm • Communication Mode: I2C (100Kbit/s and 400Kbit/s) • Controller: STM8S005KBT6 • Operating Frequency: 16 MHz • Weight : 20g 11 | P a g e 1.3.3 HC-SR04 Ultrasonic Sensor Figure 6: Ultrasonic Sensor Technical specifications (lastminuteengineers, 2022) o Operating Voltage: DC 5V o Operating Current: 15mA o Operating Frequency: 40KHz o Max Range: 4m o Min Range: 2cm o Ranging Accuracy: 3mm o Measuring Angle: 15 degrees o Trigger Input Signal: 10µS TTL pulse o Dimension: 45 x 20 x 15mm 1.3.4 A Buzzer Figure 7: The piezo 12 | P a g e Technical specifications • • • • • • Color is black The frequency range is 3,300Hz Operating Temperature ranges from – 20° C to +60°C Operating voltage ranges from 3V to 24V DC The sound pressure level is 85dBA or 10cm The supply current is below 15mA 1.3.5 10 mm LED Figure 8: 10 mm LEDS LED specifications • • • • • • • Long Life: LEDs can last over 100,000 hours (10+ years) if used at rated specifications No annoying flicker likes from fluorescent lamps LEDs are impervious to heat, cold, shock and vibration LEDs not contain breakable glass Solid-State, shock and vibration resistant Extremely fast turn on/Off times Low power consumption puts less load on the electrical systems increasing battery life 13 | P a g e 1.4 Assembly 1.4.1 HC-SR04 Ultrasonic Distance Sensor with Arduino UNO Arduino Uno GND D2 D3 5V Ultrasonic Distance Sensor GND ECHO TRIG VCC 1.4.2 LCD I2C with Arduino UNO Arduino Uno GND 5V SDA SCL LCD 16 x (I2C) GND VCC SDA SCL 14 | P a g e 1.4.3 Piezo (Buzzer) with Arduino UNO Arduino Uno GND D7 Piezo Negative Positive 1.4.4 LEDs with Arduino UNO Arduino Uno GND D4 D5 D6 LEDs Cathode Resistor with Anode (Green) Resistor with Anode (Yellow) Resistor with Anode (Red) 15 | P a g e 1.5 Coding 1.5.1 Coding for Arduino 16 | P a g e 17 | P a g e 18 | P a g e 1.6 Clips and photos of the project (evidence) 19 | P a g e Figure 9: Project model Video of our project: https://youtu.be/fnhDlIcAtyo Run end user experiments and examines feedback (P6, P7) To get user input, our team decided to conduct a brief survey The primary goal of the poll was to determine how people interact with our cutting-edge sensor parking We plan to investigate in depth: - When the project is finished - The project's flawless score - The project's unfinished point Finally, we collected three clients and demonstrated how distance sensors for automobiles operate Then we asked them to fill out our survey 20 | P a g e Figure 10: Our survey on Google forms 21 | P a g e Here are a few of the comments we gathered: Full Name Student’s ID Score Hồ Thị Hà Phương GBH190324 Goods Dislike - This is a fantastic concept - The model is still a work in progress with a lot of patchwork - Effective execution - The signaling system is not functioning as planned - Applicable in practice Trần Minh Sang GBS190217 - Excellent Concept - The model is experiencing screen issues - The notice board and display lights are quite visible Lê Huỳnh Phương Thảo GBS210318 - Sensor not recognized - Excellent concept and design - When put into effect, it will secure everyone's safety - If the automobile reverses too rapidly, the light system reacts immediately 22 | P a g e Discuss the drawback in your system and solutions for improving (P6, P7) With our system, after testing and collect surveys and questionnaire from user’s feedback, we realize some problem and drawback below: Problem and Drawback Solutions for improving Sensor can’t identify exactly distance of car in Use more sensors to improve accuracy of every angle system, draw grid for each car Because each grid, each car need a device, Optimization area, calculate number of device that make cost of this system increase with can deploy for the best quantity of cars and quantity system Some errors can broke device of make car hit Regular maintenance and check the system device Maintenance duration is too long Maintenance each device by order Split device to maintenance by group Piezo and led can’t attention for drivers, We need to change the soundspeaker louder, brighter led that can attention drivers Drivers can’t read notification on LCD Use brighter and bigger LCD, can reverse letter to help drivers can read with rearview mirrors Conclusion In conclusion, after working together on this project, we now know what the Internet of Things is and how to use it We also know how to work together and are learning how to use various electrical devices with tools and hardware such as Arduino Furthermore, because it only mimics a portion of the actual parking system, our approach needs be greatly improved in order to be useful 23 | P a g e Here is the picture when our project applies of parking References https://www.manxtechgroup.com/10-x-benefits-of-smart-parking-technology-iot/ [Accessed July 25, 2019] https://www.plasmacomp.com/blogs/benefits-of-smart-parking-solution/ [Accessed June 27 2016] Seeedstudio, I2C LCD, https://wiki.seeedstudio.com/I2C_LCD/ [Accessed August 30, 2022] Make-it.ca, LED Specifications and Application Notes, https://www.make-it.ca/ledspecifications/ [Accessed August 30, 2022] Elprocus, What is a Buzzer: Working & Its Applications, Available at : https://www.elprocus.com/buzzer-working-applications/ [Accessed August 30, 2022] 24 | P a g e ...
