Walkthrough IR thermometer

There is no need of persons to observe human temperature. it check s human temperature ,if more than normal body temperature it alerts

Things used in this project

Hardware components

Arduino UNO

PIR Motion Sensor (generic)

i have used the pir module's pyroelectric sensor because of the lack of online shopping are closed due to covid-19 pandemic.Pyroelectric sensor is less sensitive. if you use mlx90614 / gy-906 for accurate measurement of temperature and applicable in many places. i more prefer to use the mlx 90614 and gy-906

Digilent IR Proximity Sensor

Buzzer

LED (generic)

5 mm LED: Green

Resistor 1k ohm

Software apps and online services

Arduino IDE

Story

During the pandemic the ir-thermometers are widely used to detect body temperature(the fever is a main symptom of covid - 19 and body temperature is always will be more than the normal body temperature) . I seen in many places a person / health authorities checking peoples by using ir-thermometer.
Its very dispirited job , covid-19 may be affected to that person and its a dangerous attempt . In addition to all , these operations are against the social distancing.

Checking with ir thermometer

I think the Portable IR thermometer is helpful for government authorities and who needs / using ir-thermometers.
The Portable IR thermometer contains a pyroelectric sensor it only detect the human, a ir-proximity sensor to detect the person in front of the Portable IR thermometer , a buzzer and two LED's green and red.
( use mlx90614 / gy-906 )
In the case of using pyroelectric sensor you will need to cover one side of the sensor

use aluminium foil to cover one side

and it need a amplifying circuit

lm358 op-amp

The Portable IR thermometer is fixed in the entrance of the door .when people comes and stand in front of Portable IR thermometer ,the ir proximity sensor will detect and starts to measure body temperature , when the people have normal body temperature the Green LED will bright .when the people have more than the normal body temperature it will alerts and Red LED will bright

Code

code

int green = 10;
int red = 11;
int buzzer = 12;
const int proximity = 8;
const int tmpsensor = A1;
int sensorvalue = 0;

void setup() {
  Serial.begin(9600);
  pinMode(green,OUTPUT);
  pinMode(red,OUTPUT);
  pinMode(buzzer,OUTPUT);
  pinMode(proximity,INPUT);
  pinMode(tmpsensor,INPUT);

}

void loop() {
  boolean proximity = digitalRead(proximity);
  if(proximity == HIGH){
    sensorvalue = analogRead(tmpsensor);
    Serial.println(sensorvalue);
    if(sensorvalue > 500){
      digitalWrite(red,HIGH);
      digitalWrite(buzzer,HIGH);
      
    }else{
      digitalWrite(red,LOW);
      digitalWrite(buzzer,LOW);
      digitalWrite(green,HIGH);
      
    }
    
  }else{
    
    digitalWrite(red,LOW);
    digitalWrite(buzzer,LOW);
    digitalWrite(green,LOW);
    
  }
  
}
