Sorry guys,if I have been sounding funny.My professor gave me this project.I found a dew sensor circuit on the internet.But he said that he needed a circuit that can display the humidity of the atmosphere on LCD/LED diplay.
About sensors,well,I have read a little about them.I understand that they work on capacitance principle.As I live in India,and more importantly in small city,I will have to rely on the sensor that my electronics dealer makes available.I am sorry that I dont have other options there.
So guys,I would be glad if you would point me to a circuit,which is simple enough for me to understand.
