In part, Mimi will measure the pressure from the soil so as to follow the circuit below picture. Without pressure from the soil through the circuit voltage divided by the condition that the voltage passes through the ADC will be in the range of 0-5 volts, so it can be used only with RLV resistance 330 KB and RMV resistance ohm circuit voltage will be equal to the ratio of 5.6 ohm, which has 59 KB: 1 voltage divider circuit are supplied as by pressure from the soil is 300 volts when the pressure will break through. Bracket pressure equal to the RMV (335.6/5.6) x300 = 5.00 volts where the pressure will be a rectifier, AC voltage Rectifier and then transmitted by a visit to ADC, microcontroller, calculate, and compare the pressure value from the soil.
