Story

To help reduce local transmission of covid19, sanitizers should be placed and accessible at the first contact point of every home or organization which is the door/gate. This is only possible with an effective and affordable automatic sanitizer, BIYS. BIYS is an open-source easy to build automatic sanitizer. The idea is to create a self-discharging sanitizer that can be easily built by anyone while also ensuring it can be easily embedded in existing systems. The design features component already used by the DIY community making it easy for anyone to build a functional unit using locally available materials. BIYS make it easy for people to comfortably use sanitizers, all you have to do is place your hand below the discharge point for less than a few seconds and you have the sanitizer in your hand.

Key features

Contact through touching with sanitizer container can be avoided

No time is wasted trying to apply the sanitizer to the hand

The needed amount of sanitizer is discharged at a time reducing underuse or wastage.

Schematics

Code

BIYS demonstration code

/*the  obstacle status variable allow us to determine the  presence of a person's  hand*/
volatile byte obstacleStatus=LOW;
int buzzerPin=2;
int irSensor=1;
int pumpPin=3;
void setup() {
  //This is a program written to demonstrate BIYS
/*the IR pi*/
pinMode(OUTPUT, buzzerPin);
pinMode(INPUT,irSensor);
pinMode(OUTPUT,pumpPin);

attachInterrupt(digitalPinToInterrupt(irSensor),updateStatus,FALLING);
}
void  updateStatus()
{
  obstacleStatus=HIGH;
  }

void loop() {
  // put your main code here, to run repeatedly:
  if(obstacleStatus==HIGH){
    digitalWrite(pumpPin,HIGH);
    digitalWrite(buzzerPin,HIGH);
    delay(100);
    digitalWrite(buzzerPin,LOW);
    delay(1900);
    digitalWrite(pumpPin,LOW);
    obstacleStatus=LOW;
    }
}
