Introduction: Human Body Induction Alarm Based on Arduino With Arduino UNO, Infrared Sensor Module,Buzzer Module
ICStation team of research and development department have made this project about the human body induction alarm .It uses DC5V voltage to work. When someone is appearing in the inducing area of infrared sensor and the whole system will use both sound and light to alarm. The inducing distance is 7m.And it is a simple and cheap alarm which is suitable for a protection against burglars to home, office, warehouse and laboratory.
Features of human body induction alarm :
1.When the hardware initializes, the buzzer will sound and the LED lights will flicker.The whole process keeps for 3-5 seconds
2.If there is no one appearing in the inducing area of infrared sensor, the buzzer will not sound and the LED light will not flicker.
3.If there is someone appearing in the inducing area of infrared sensor, the buzzer will sound and the LED light will flicker.The alarm of both sound and light will keep for 5 seconds.
4.If there is someone appearing in the inducing area of infrared sensor and remain still, the alarm will stop after 5 seconds of sound and light alarm.And only when the human body is moving during the inducing area of infrared sensor and then will trigger the alarm again.
