The capacitance increases when the human gets closer to the metal plate. By measuring this capacitance, the distance between the human and the sensing plate can be estimated.
A.C Bridges can be used to measure unknown capacitance like , Schering Bridge. To know how Schering Bridge can measure unknown capacitance , please go through the below link: www.electrical4u.com/schering-bridge-measurement-of-capacitance-using-schering-bridge/
Don't forget to check the Description .There is the main gist of whole story.
Very Good. Please suggest any working circuit diagram with component's value.
Good channel
Thank you Yogesh Patil
for the inspiring comments :-)
Howis capacitive measured? I mean, is the target object grounded.
What if we charge the plate with negative polarity
Sir how to measure CAPICTANCE
