This document summarizes a student project to develop a prototype black box device for passenger cars. A group of 5 students worked on the project under the guidance of a professor. The black box would help with post-crash analysis and quicker emergency response. It involved designing circuits and components for an emergency rescue system using a microcontroller, GSM and GPS modules. This would detect accidents and send alerts. It also included a front-desk video recording system using a WiFi camera and sensors to monitor vehicle maintenance parameters like temperature, oil level etc. The project was conducted in phases including literature review, design, prototype development, testing and presentation.

by providing safe and
secure traveling to the
travelers.

6. Problem Statement :
Whenever an accident is being met, the people
nearby call the ambulance. The problem associated
with this is that the victims depend on the mercy of
nearby people. There are chances where no people
nearby the accident spot or people who are around
neglects the accident. This is the flaw in the manual
system.

7. The objectives of the project work are stated as follows:
 To study existing black box design and configuration.
 To design prototype of proposed system of Black box for road vehicles.
 To develop a system to get maintenance alert.
 To get regular vehicle data parameters such as engine temperature, coolant level and
oil level.
 To develop a system that records the front desk videos for post crash analysis.
 To conduct testing of elements of developed prototype model followed by validation
of the proposed approach.

15. The ESP8266 module enables
microcontrollers to connect to 2.4
GHz Wi-Fi, using IEEE 802.11 bgn.
It can be used with ESP-AT
firmware to provide Wi-Fi
connectivity to external host MCUs,
or it can be used as a self-sufficient
MCU by running an RTOS-based
SDK.

Arduino Program for Emergency Rescue System

17. GSM - SIM800A
The SIM800A modem has a SIM800A
GSM chip and RS232 interface while
enables easy connection with the computer
or laptop using the USB to the Serial
connector or to the micro-controller using
the RS232 to TTL converter. Once you
connect the SIM800A modem using the
USB to RS232 connector, Once a serial
connection is open through the computer
or your micro-controller you can start
sending the AT commands. When you
send AT commands for example “ATr” you
should receive back a reply from the
SIM800A modem saying “OK”

18. GPS Module
Global Positioning System (GPS)
satellites broadcast signals from space
that GPS receivers, use to provide
threedimensional location (latitude,
longitude, and altitude) plus precise time.
GPS receivers provides reliable
positioning, navigation, and timing
services to worldwide users on a
continuous basis in all weather, day and
night, anywhere on or near the Earth

19. Results of Emergency Rescue System:

20. The ESP32-CAM is a small size, low
power consumption camera module based
on ESP32. It comes with an OV2640
camera and provides onboard TF card
slot.The ESP32-CAM can be widely used
in intelligent IoT applications such as
wireless video monitoring, WiFi image
upload, QR identification, and so on.
Front desk video recording system.

21. FEATURES OF LM35 ANALOG
TEMPERATURE SENSOR:
Provides analog output directly readable in
degrees Celsius
Output voltage corresponds to 10.0mV/°C
-55 to 150°C measurement range with
±0.5°C accuracy°
5V compatible. 3.3V uC compatible if the
sensor is run off separate 4 to 20V supply.
If you have a uC like an Arduino and you
want to measure temperature, the LM35 is
one of the more popular temperature
measurement ICs to use.

22. Tempreture sensor testing:

23. LDR (Light Dependent Resistor) as the
name states it is a special type of resistor
that works on the photoconductivity
principle means that resistance changes
according to the intensity of light. Its
resistance decreases with an increase in
the intensity of light. It is used to check
quality of oil.

24. Servicing alert testing :

25. Ultrasonic Sensor
An ultrasonic sensor is an electronic
device that measures the distance of a
target object by emitting ultrasonic
sound waves, and converts the
reflected sound into an electrical
signal. In our system this sensor
provides the exact oil level in the
engine.

27. Component Price (Rs.)
Arduino nano 1500
GSM Module 2500
GPS Module 750
WIFI Camera 500
Temperature Sensor 250
LDR - LASER 250
Ultrasonic Sensor 300
Casing 1000

28. Future Scope:
• With the further advancement as soon as the vehicle
meet the accident the message should be sent to
nearest police station and hospital.
• This system can be implemented by insurance
companies to do post crash analysis.

29. Conclusion:
The proposed system makes good use of GPS and Android
applications by providing safe and secure traveling to the
travelers. This is done using wrong path alert mechanism. It
helps to find the current location of the vehicle. Traveler’s
safety mechanism is also provided using temperature,
ultrasonic, smoke and accelerometer sensor. As per traveler’s
safety concern, the proposed system also gives alert massage
to authorized mobile so that authorized person also knows
about their traveler’s safety.
