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)
