This document describes a low-cost school bus tracking system using IoT technologies. The system uses an ESP8266 microcontroller with a GPS module to track the bus location and upload it to a database in real-time. An Android app then downloads the location data and plots it on a map. RFID tags on student ID cards are read to detect when students board and disembark, triggering push notifications to parents. The system costs less than $20 compared to $150-200 for similar systems. It aims to address issues like students missing buses or getting off at wrong stops by providing real-time tracking and notification.

- 1. INTRODUCTION METHODS AND MATERIALS DRAWBACKS CONCLUSIONS RESULTS REFERENCES The aim was to develop a low cost tracking system. The ESP costs $3 when Arduino costs $6 and Raspberry pi, $25. The entire system cost less than USD20 when Arduino +GSM systems cost USD150 and Raspberry Pi systems cost USD 200. Raspberry pi systems have been known to show packet loss rates as low as 0-0.50%. Packet loss rates of ESP8266 are close to that of Arduino at 1-2%. The components used for the tracker are ESP8266 microcontroller which has a built-in WiFi module, Ublox 6M GPS module and a MFRC522 RFID Reader. The microcontroller constantly uploads the location input by the GPS module to a mysql database hosted on an Apache server. A front-end android application downloads the data from the database and plots the location on a map in real time using Google Maps API for Android. The id cards of students are embedded with an RFID tag. The RFID reader in the tracker which is positioned at the entrance of the bus will automatically identify each student as they board/alight. The microcontroller will then invoke a PHP script which will send a push notification using Firebase Cloud Messaging (FCM) to the respective parents’ mobile app, notifying them of the drop off/boarding location and time. • The range of the RFID reader is as low as 3cm and hence impractical for commercial purposes. • The http connection is not encrypted and hence easily susceptible to hacking. • The project assumes WiFi to be ubiquitous without which, the system will fail. • There is an initial delay of almost 1minute for the GPS module to startup on power up. The commute of students from home to school and back has always been a source of concern for parents. Students often get on the wrong buses and get off at the wrong stops. Bus drivers maybe unable to identify all students and will not know in time if a student is missing. Parents have no way of knowing if their ward is safe until the evening when the bus returns. While some schools have already implemented GPS tracking of buses using GSM, that do not give real time updation or individual information of students. Raspberry Pi systems have been known to give real time information but the cost is too high for it to be a replacement for GSM systems. This project on implementation, will be a means to monitor school buses comprehensively including the speed, the people onboard, adherence to route, time etc. • Pham Hoang Oat, Micheal Drieberg and Nguyen Chi Cuong , Development of Vehicle Tracl<ing System using GPS and GSM Modem , 2013 IEEE Conference on Open Systems (ICOS), December 2 - 4, 2013, Sarawak, Malaysia. • Prof.Mr.Y.B.Mane, Advanced Vehicle Monitoring and Tracking System based on Raspberry Pi,, IEEE Sponsored 9th International Conference on Intelligent Systems and Control (ISCO)2015 Smart School Bus : An IoT Based School Bus Monitoring System Judy T Raj, CS8 Group no : 12 Reg no: 12141828 Guide: Prof. Annie Julie Joseph ABSTRACT The project aims to develop a low cost vehicle tracking system that will ensure the safe commute of school children. It involves Internet of Things application that tracks the geographic location of school buses in real time and display it on a map in a mobile app. The application gives information about the bus, speed and designated route. It is aimed at a user base which incudes the faculties, bus drivers and parents. It is expected to solve the problem of students missing the bus and ensure the safe pick up and drop off of students by providing the tracking facility at affordable costs.
