 		 #175840 - yes, don't
Responding to: ???'s previous message
-I am using capacitive power supply, from Mains for this project so do not have option to use metal touch plates.

However any suggestion to implement this in 8051?

yes, don't.

to risk life and limb to experience some fancy stuff is ridiculous
a) a power supply is not that expensive
2) a power supply is reusable for ypur next project
