- 3. INTRODUCTION In this modern era , technological development lead the creation of sky scraper buildings and dwellings which increase risks of losing life due to natural and manmade disasters. Many people died by trapping under debris as their presence cannot detect by the rescue team. PIR sensor based semi-autonomous mobile rescue robot is developed which can detect live human being from an unreachable point of disaster area. This project uses Bluetooth module and sends information to a website/Android device, as soon as soon a human is detected.
- 4. OBJECTIVE The objective is to develop PIR sensor based semi autonomous robot with a Bluetooth module and interface it with user application for detection of live human beings from unreachable parts of disaster area.

- 7. ARDUINO UNO Arduino uno is an open source micro controller based board. It is designed on the micro chip ATMEGA328P micro controller. It has 28 pins in which 14 are digital I/O pins,6 are analog pins. Arduino uno is a microcontroller board based on 8-bit ATmega328 microcontroller. Along with ATmega328p,it consists other components such as crystal oscillator, serial communication, voltage regulator, etc., to support the microcontroller.

- 9. PIR SENSOR PIR sensor are also called as PID(passive infrared detector). PIR are fundamentally made of a pyro electric sensor, which can detect levels of infrared radiation. PIR sensor works entirely by detecting infrared radiation effected by reflected from objects. PIR sensor has 3 pins: 1. VCC 2. Ground 3. Digital output pin

- 11. DTH11 SENSOR DTH11 is a basic ultra cost digital temperature and humidity sensor. DTH11 is a composite sensor that contains a calibrated digital signal output of temperature and humidity. It has a high reliability and excellent long term stability. Output digital signal indicates humidity values of surrounding environment. .
- 12. FEATURES OF DHT11 SENSOR Operating Voltage: 3.5V to 5.5V. Operating current: 0.3mA (measuring) 60uA (standby) Output: Serial data. Temperature Range: 0°C to 50°C. Humidity Range: 20% to 90% Resolution: Temperature and Humidity both are 16-bit. Accuracy: ±1°C and ±1%
- 13. BLUETOOTH MODULE • HC-05 is a Bluetooth module which can communicate in two way. Which means, It is full-duplex. We can use it with most micro controllers. Because it operates Serial Port Protocol (SSP). • The module communicate with the help of USART (Universal Synchronous/Asynchronous Receiver/Transmitter ) at the baud rate of 9600. and it also support other baud rate. So we can interface this module with any microcontroller which supports USART. • The HC-05 can operate in two modes. One is Data mode and other is AT command mode. • When the enable pin is "LOW" the HC-05 is in Data Mode. If that pin set as "HIGH" the module is in AT command mode. Here we operate this module in Data Mode. FEATURES: •Operating Voltage: 4V to 6V (Typically +5V) •Operating Current: 30mA •Range: <100m •Works with Serial communication (USART) and TTL compatible •Can be easily interfaced with Laptop or Mobile phones with Bluetooth
- 15. MOTOR DRIVE L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. FEATURES: •The operating voltage of this LCD is 4.7V-5.3V •It includes two rows where each row can produce 16-characters. •The utilization of current is 1mA with no backlight •Every character can be built with a 5×8 pixel box •The alphanumeric LCDs alphabets & numbers •Is display can work on two modes like 4-bit & 8-bit

- 17. WORKING The robot has two sides ,receiver side and the transmitter side. The transmitter side consists of ATMEGA328p microcontroller(Arduino uno). The inputs to the microcontroller are PIR sensor,DHT11 sensor and Bluetooth module. Power supply of 12V Battery is connected to the circuit. The output i.e., the detection of human beings and humidity values can be viewed in Android through Bluetooth receiver module. The PIR sensor detects the human radiations coming from the live human body. Once PIR sensor detects the signal from the victim it notifies the Arduino. The Arduino immediately sends the signals to the Android device through the Bluetooth receiver module and gives information about the victim and the surrounding humidity. By this, the user will know about the human beings stuck in the disaster. It monitors sensor data and sends to cloud through Bluetooth module.
- 18. ADVANTAGES This system is an effective and a safe system to ensure that there are no humans left behind in a rescue operation. The system is safe even for the user because of the use of robotics and no manual work in field. The design of this robot is simpler to understand. This system provides high reliability. They work efficiently in environment where it might be dangerous for humans. Precise positioning and repeatability of movement since good stepper motors have an accuracy of 3-5%of a step and this error is non- cumulative from one step to next.

- 21. CONCLUSION The development of robots for domestic environments is a challenging task. One of the most basic problems is how to enable them to detect and identify humans robustly. Live human detection using PIR sensor has been developed by integrating features of all the hardware components used. Presence of every module has been reasoned out and placed carefully thus contributing to the best working of the Unit. Secondly, using highly advanced IC’s and with the help of growing technology the detection of human being is done for protecting them in disaster prone area.
