Human Detection by Live Body Sensor

December 28, 2011

HUMAN DETECTION BY LIVE BODY SENSOR projects main idea is to develop a application which can detect human body using sensors.This application can be mostly used in health care systems.

Working procedure : When a intruder is detected PIR sensor output increases which in turn is filtered to make sure that the increased output voltage is due to the human intruder.

  • This signal is amplified and converted to TTL logic 0-5v
  • Amplifier output is connected to the microcontroller, controller detects the transition from 0-5v as the presence of the human
    • Controller then activates the  siren (PWM driven from controller)

HARDWARE: 

1. Micro controller


2. interfacing human heat detection Sensor                                                                        

3. Power Supply

8.BUZZER Indication
