actually i am making water level controller. and receiving voltage by completing path from water. currently i am getting 3.34 volts on the base from the water. if i take output BJT acts as a inverting switch . but instead when i take output from emitter to behave it as non inverting switch i get the same voltage that is on the base. but i want to have 5v. fixed.
