AIM:  Design and development of “Automatic Plant Irrigation System” using Arduino microcontroller.




Monitoring field conditions is the foundation of modern agricultural management. In order to improve the efficiency of the data collection procedure, and to improve the precision with which agricultural operations are managed. This system automatically reports environmental conditions in real-time.

               In this project the temperature sensor and moisture sensor are interfaced to the microcontroller. The sensor continuously checking the moisture level in the soil and will be updated to the controller , and if it is less than the pre defined level then the motor will turn ON automatically. Here LCD is interfaced to display the status of moisture. Along with this temperature sensor senses temperature and for high temperature DC Fan will be ON.  

    This project uses regulated 5V, 1000mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer. Here Arduino uno is microcontroller.
