  1. 1. V.LAKSHMAN KUMAR -20Q65A0240 N.CHAKRAVARTHI -19Q61A0220 N.KARTHIKEYA -20Q65A0230 G.DAYANAND -20Q65A0213 LIVE HUMAN BEING DETECTION USING RF MODULE 1
  2. 2. CONTENT  Introduction  Requirements  Features  Block diagram  Arduno microcontroller  Crystal oscillator  Helical Gear Motor  PIR motion sensor  Advantages  Disadvantages  Applications  Conclusion 2
  3. 3. INTRODUCTION  The advent of new high-speed technology and the growing computer capacity provided realistic opportunity for new robot controls and realization of new methods of control theory.  This technical improvement together with the need for high performance robots created faster, more accurate and more intelligent robots using new robots control devices, new drives and advanced control algorithms. 3
  4. 4. REQUIREMENTS  Power supply  Micro controller  Dc gear motor  Relays  PIR sensor 4
  5. 5. FEATURES  Compatible with MCS-51® Products  8K Bytes of In-System Programmable (ISP) Flash Memory  Endurance: 1000 Write/Erase Cycles  4.0V to 5.5V Operating Range  Fully Static Operation: 0 Hz to 33 MHz  Three-level Program Memory Lock  256 x 8-bit Internal RAM  32 Programmable I/O Lines  Three 16-bit Timer/Counters 5
  6. 6. BLOCK DIAGRAM 6
  7. 7. LIVE HUMAN BEING DETECTION USING RF MODULE 7
  8. 8. ARDUINO MICROCONTROLLER  Arduino microcontroller is based on UNO AtMega328.  It is used to receive commands sent by the user via the internet and processes according to the code and also used to control the motors.  Wi-Fi module ESP8266 is also connected with the arduino so that Wi-Fi facility can be provided to the robot. 8
  9. 9. CRYSTAL OSCILLATOR  A crystal oscillator is an electric oscillator type circuit that uses a piezoelectric resonator, a crystal, as its frequency-determining element.  To provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.  Crystal oscillators are having a frequency range from 32khz to 200mhz 9
  10. 10. HELICAL GEAR MOTOR  A unit which creates mechanical energy from electrical energy and which transmits mechanical energy through the gearbox at a reduced speed.  A gearhead and motor combination to reduce the speed of the motor to obtain the desired speed or torque. 10
  11. 11. PIR MOTION SENSOR  1,Wide Working Voltage Range: DC 4.5V- 20V  2,Detection Distance: 3 to 7m (can be adjusted)  3,Blockade time: 2.5s (Default)  4,Work temperature: -20-+80°C 11
  12. 12. ADVANTAGES  Less man power.  Saves human lifes.  Ranges upto 30HZ-300GHZ.  Fast in response.  Easy to maintain. 12
  13. 13. DISADVANTAGES  Not easy to operate on uneven surfaces.  Only skilled person can be control.  Voice command is absent. 13
  14. 14. APPLICATIONS  Used in military frequencies.  Used in wars.  Used in army bases to find hidden terrorists in buildings. 14
  15. 15. CONCLUSION  The project “HUMAN DETECTION ROBOT” has been successfully designed and tested.  Integrating features of all the hardware components used have developed it.  Presence of all reasoned out and placed carefully thus contributing to the best working. The controller makes use of a PIR based input sensor to sense the human being and give us an alert indication.  Also use of a remote which is used to control the robot. 15
