Human body detection sensor based on Arduino
This detecter is based on Arduino human body induction experiment, the sensor detects human's body approaching, when the man reaches its induction range, it will trigger the alarm buzzer to make a sound.
Make the project, you will need the items below:
1. Kuamn Arduino Uno board*1
2. Kuman Buzzer*1
3. Kuman Human body detection sensor*1
4. Dupont cables
How to wire?
Buzzer:
Negative electrode（-）---------- GND
positive electrode（+）----------- VCC（5V、Connection development board Digital pin 8）
Human body detection sensor:
GND -------------------- GND
VCC -------------------- 5V
OUT ------------------- Connection development board Digital pin 2
General View:
Code:
int ledPin = 13;
int fengming = 8;
int sensor = 2;
int val = 0;
int i=0;
void delay1ms(void) //devintion -0.25us
{
unsigned char a,b;
for(b=190;b>0;b--)
for(a=2;a>0;a--);
}
void setup()
{
Serial.begin(9600);
pinMode(ledPin, OUTPUT); // set as output number pin
pinMode(sensor, INPUT); // set as input number pin
pinMode(fengming, OUTPUT); // set as output number pin
}
void loop()
{
for(i = 0; i <= 100; i++)
{
if(i==100)
{
i=0;
}
else
{ val = digitalRead(sensor); // read input pin
if(HIGH == val)
{
digitalWrite(ledPin,HIGH); // set LED high level
digitalWrite(fengming,HIGH); // set buzzer as high level
delay1ms();
}
else
{
digitalWrite(ledPin,LOW); // set LED high level
digitalWrite(fengming,LOW); // set buzzer as high level
delay1ms();
}
}
}
}
