The output of GPS module is in NMEA format which includes data like location in real time. This module operates in L1 frequency (1575.42 MHz) and up to a fix territory of about 10 meters in sky, it generates accurate information. The connection between arduino uno and GPS module is set by connection transmit pin Tx of GPS to arduino uno Rx pin. The main function of this module is to transmit location data to the arduino uno. SIM28ML GPS module is preferred for this project. In order to make communication between GSM mobile and arduino uno we had only used Rx pin of GSM module and Tx pin of arduino pin. It is basically tri-band work on various frequency range (EGSM 900 MHz, DSC 1800 MHz and PCS 1900 MHz). SIM900 GSM module is preferred for this project for communication between accident detector and alert system and mobile phone. It basically gathers information from vibration sensor module and GPS sensor module, process it and display output to LCD and send message alert to the mobile. It is the central control unit for the project Accident detector and alert system. Now, let’s talk about the component used in this system and circuit connection. This circuit basically consist of arduino uno, GSM module, GPS module, vibration sensor module and LDC module. The circuit of accident detection and alert system is shown in figure 1. Parts List of Accident Detection and Alert System using ArduinoĬircuit Description of Accident Detection and Alert System using Arduino
The Accident Detection and Alert System using Arduino prevent the uncertain death after accident because this system send the message alert to the hospital or police station. Accident is increasing due to increase in number of vehicles as a result every year the number of death is increasing. The Accident Detection and Alert System using Arduino is very sufficient and worthy to be implemented in the vehicle specially in developing country like Nepal, India, Bangladesh etc. Introduction of Accident Detection and Alert System using Arduino
