The inference engine consists of four AND operators that select minimal value input for matlab output. This inference engine accepts four inputs from fuzzifier and applies matlab min max composition to obtain matlab output R values. The min max inference method uses min AND operationbetween matlab four inputs. Fig. 7 shows this variety of inference method. variables in engineering region corresponds to mapping of two purposes. The ultrasonic fogger circuit is not challenging to design. These foggers have very few moving parts and require no special temperature and force circumstances. This form of design and working of ultrasonic foggers makes them engineering low preservation and competitively priced equipment. Moreover, they are easy to set up and use. When used for agricultural functions, matlab is essential that there are no free water particles that can damage matlab plants and that water doesn’t condense on matlab plants or their growing mediums. Since ultrasonic foggers produce water particles engineering matlab size of 5 microns or less, there isn’t any chance of condensation on matlab plants’ surface or their transforming into medium.
