Atmega plant irrigation project


Irrigation is the most important practice and most intensive task in daily agriculture sector. To know when and how much to water the plants are two important aspects of irrigation. This can be done automatically using sensors and it can be determined when plants may need water. This plant irrigation system project is intended to observe the moisture content of the soil to provide a correct amount of irrigation to agricultural fields and make sure the effective growth within the plant. Irrigating the fields by switching the pump ON/OFF, this project automates the process manually. This project is implemented by using a microcontroller atmega328p, programmed like to collect input signals that measure the moisture content of soil through sensing arrangement. Because the capacitive moisture sensor is removed out from the water, the LCD indicates the dry condition. The microcontroller produces an output that drives a relay and operates the water pump on receiving the signal. Hence the system reduces human intervention and provides required irrigation to the field.
