ankit..again u r confusing urself. Be practical..just Dnot try to Copy our work 4m snap shot.just follow the ckt Diagram. During my work i used High Glow LED in each ckt. bt i found dat whn i supply all the 4 sensors ckt, ADC ckt n uC ckt 4m one 5v DC source, der is huge current drop at LCD, as a result LCD ddnt glow brightly .so i modifed the power supply section n gave 2 5v DC sources . one to al 4 sensors none to ADC n uC ckt. now u sudnt confused wid dat.

thanks MM and chinmay

i an working on humidity sensor actually i want to make it by my own

i don't want to use the direct sensor can u suggest me how to make humidity sensor

and one thing more in soil moisture sensor there are copper probes but there is one disadvantage of copper probe it will corrode after some time due to water can u suggest me some other type of probes which is not corrosible????
