Smart irrigation system with GSM module using DC-DC converter with Regenerative Snubber
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 9
Abstract
To reduce the man power for irrigating the field. To minimize the wastage of water used for irrigation. To save the electricity cost by operating the water pumping motor by utilising solar power. At power supply unit, Z-Source converter is used to supply regulated supply with snubber to reduce the voltage drop due to leakage inductance and to achieve less switching loss. The simulation is done with MATLAB and hardware prototype is developed and tested successfully. The irrigation process is completely automated by using the Arduino Mega microcontroller with GSM module for sending the current status to the farmer. Solar is the major renewable source in India, is converted into electrical energy for supplying the entire system. Various sensors are used to measure the physical parameters in order to control flow of water to the field. The sensed signals are sent to the Arduino Mega to ON/OFF the DC motor pump set. GSM will give us information about the current status of the motor pump set i.e. whether the motor is in ON or in OFF state. In this proposal the water flow to field is improved by sensing the rainfall by using rain sensor. When the rain fall happens, the motor-pump set is switched off to save, both the water and electrical energy
