DISINFECTION MACHINE SIMULATION USING TINKERCAD

In this inscrutable we are going to see how to make a simulation of Disinfection Machine,Contact less Automatic Sanitizer is an disinfection machine because we wont use our hands to operate the machine instead the Proximity infrared sensor sense our hand movement near to it and dispense the sanitizer,This will be more helpful to the pandemic situation.Before getting into hardware it is a best practice to do simulation and check our circuit.

Step 1: Step 1:CONNECTING PIR SENSOR WITH ARDUINO

Connecting PIR Sensor to Arduino

PIR SIGNAL PIN--------------------->ARDUINO PIN 13

PIR POWER PIN--------------------->ARDUINO PIN 5V

PIR GROUND PIN------------------->ARDUINO GROUND

Step 2: Step 2:Connecting Output Device Bulb to ARDUINO

It is necessary to have an output device to indicate the hands close to PIR Sensor.

Bulb Terminal 1------------------------------------>Arduino PIN 12

Bulb Terminal 2------------------------------------>Arduino GROUND

Step 3: Output & Program for Step 1 & Step 2:

We can see that by sensing the hand movement near the PIR Sensor the controller actuates the bulb to turn on.

Step 4: Step 3:Adding Buzzer to the Circuit,Program & Output

In this one more output device Buzzer is added to pin No-7 of ARDUINO and the image clearly shows the connection and program

Step 5: Step 4:Adding Servo Motor With the Circuit.

To show the sanitizer open and closing a Servo motor is used.

CONNECTIONS

SERVO PIN POWER---------------------------------->ARDUINO PIN 5V

SERVO PIN GROUND-------------------------------->ARDUINO PIN GROUND

SERVO PIN SIGNAL---------------------------------->ARDUINO PIN 8

Step 6: Step 5 Final Output and Program

Here the PIR Sensor in the machine senses the hand movement and the hand movement sensed is indicated by a light and buzzer sound,The servo turns 180 degree right to indicate the opening of sanitizer ad back to 0 degree to show the closing of Sanitizer.

The PIR sensor has a Potentiometer back side to adjust the Proximity range and time to adjust as per our requirement.
