Abstract
Automatic plant irrigation system is created by assembling the electronic items like Arduino, GSM, transistors, receiver/ transmitters, sensors, etc. With the input of desired programme set by coding software. Arduino functions as a master brain of the system as it is capable of interpreting the programmes and data fed. Moisture sensors/ rain sensors sense the moisture content of the field and rain if any, the data is sent to Arduino via transmitters/receiver which intern analyse the data and switch on/off the motor based on the dryness/ wetness of the field. Our system is capable of sending SMS to user's mobile phones if field remains dry and if pumps isn't working. The system is also designed such a way that even an illiterate farmer can recognise the status of field watering via light signal.
