Abstracts: The purpose of this project is to monitor the parameter of soil and control those parameter to improve the crop quality. Here the parameter like moisture and light intensity will be measured and will be given to pic controller for controlling purpose, based on the measured signal. As per the control signal dc motor turn on/off . The voltage induced in soil moisture sensor is propositional to the resistivity of the soil then these signal fed to the pic controller, then data displayed on LCD . Light intensity sensor produce voltage as the resistance of the LDR changes according to the intensity of the sun light .it is displayed on LCD. DC motor on /off as per the control signal from drive circuit. The action will be taken to maintain that parameter near to set point. For wireless data transmit zigbee used in this project.
