This paper presents the design and realization of a ATMega8535 microcontroller based instrument for measuring soil moisture. Two probe for soil moisture sensor. This soil moisture sensor is connected to signal generator. When the soil moisture changes, then the impedance of sensor will change. This the frequency of output signal generator changes according to the soil moisture. This frequency change is then detected and used for knowing the soil moisture level. The instrument is also equipped with an on-off control signal that can be used for controlling the soil moisture level.
