Project Title
WIFI BAsed Sensor System
Abstract
Internet of Things based GPS & GSM tracking system with a user-friendly web page interface that enables transportation industry to keep track of their vehicle with the timestamp. This project also involves the data collection from different sensors like the temperature sensor and the light sensor that can help to provide an alert if required conditions are not matched for carrying some sensitive goods like medicine.
Introduction
The project shows the implementation of Internet of Things based GPS tracking system with an add-on feature that is the collection of data from sensors attached to the microcontroller. The data is being stored on APACHE web server running on raspberry pi to eliminate the problem of memory storage space on the hardware. The output is being shown on the web page with a user-friendly interface that will show the latitude & longitude of the current location, temperature, and luminosity at every timestamp. The aim of this project is to make a tracking system with a user-friendly interface that can be used to track the route taken by the vehicle and ambience like temperature and light conditions so the owner need not worry about the illicit use of their vehicle.

Hardware Interface
The hardware design includes PCB designing using cadsoft Eagle(software for PCB board designing). The circuit of developed PCB board includes interfacing peripheral like SIM808(GSM/GPS module), ESP826( Wi-Fi module), LSM303(Accelerometer & Magnetometer) with ARM cortex-M3 microcontroller and raspberry Pi. I2C, UART and TCP/IP are the three communication protocols that are being used in the project for establishing communication between temperature/light sensor, SIM808/ESP8266 & raspberry pi and ARM microcontroller respectively.
Software Design
The software has been developed on FreeRTOS using C/C++ programming language including features of real-time embedded system. The software involves device driver development for I2C and UART protocol which are used to establish communication between SIM808(GSM/GPS module) & ESP8266(Wi-Fi) with the microcontroller. The code also includes implementation of fetching data like latitude & longitude of the current location, temperature, and luminosity at every timestamp. The data that is being collected on real time basis from the peripheral devices is continuously transmitted to the server(Raspberry Pi) by ESP8266 module using TCP/IP protocol. Socket programming is written on the server(Raspberry Pi) which is continuously listening to the ESP8266 module. On receiving data from the client(Microcontroller) the data is being manipulated and is being able to be displayed on the user-friendly web page using PHP language.
Implementation
This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.
Testing & Technical Challenges
Describe the challenges of your project.
- First and very important aspect for any project is requirement gathering.
Make a smooth transition to testing section and described what it took to test your project.
Include sub-sections that list out a problem and solution, such as:
Issues
#1 LPC17xx UART Rx FIFO
- LPC17xx UART not able to receive more than 16 bytes
- Resolution :
- Used interuppt to solve this problem.
Conclusion
The project is based on embedded platform, implementing the concepts of semaphore, Task scheduling, queues etc. Addendum to this we have also implemented features of networking like socket programming and interfacing our output with a user-friendly interface on the web page using Internet of Things. This project helped us in learning a complete embedded application from hardware design till user interface that can be used at a commercial level.
