    i am middle of engg project . to make an automatic irrigation system ,using plc , main problem is humidity sensor which i am using gives out put of 0-5 volt but plc require more output for better results,...can any one suggest a voltage amplifier or any circuit using op amp

    Try to use op amp non inverting amplifier with gain equal to 2V/V (R1 = R2).
