So ,when the sensor is in the vacuum, it will have a specific capacitance and when it is with virus the value of capacitance will change.
I found the value in the vacuum equal to 70,8pF and the value with virus equal to 10240F. So I will understand the difference of value on sensor.
Ιt's up to us whether we will use Arduino.

 

Please show your math. Those numbers for the virus are unrealistic.
