The irrigation of the agricultural summer crops plays a substantial role in the quality and quantity of the crop production. One machine that allows us to irrigate our crops correctly and easier than other means is the water reel. It allows us to irrigate uniformly without damaging the plants. It irrigates larger areas, it’s easy to transfer and install. The supervisor that we will build, provides advantages in order to make the irrigation simpler, with higher accuracy and without any risk damaging our crop. The user of the machine has the supervision of the water reel remotely with the help of short messages notifications (sms). He has the ability to know at any time the location of the machine, the speed, the exact time left to complete the irrigation and the distance left. The benefits that it provides us cover the financial part, time saving, safety of smooth operation and easier planning of the rest of our workload. It saves us time and money from the need of unnecessary trips to supervise the reel. It provides us the safety that if something happens and interrupts the normal operation of the reel we will be notified promptly, so that we can intervene and correct the damage, without destroying our crop. Knowing the exact time left to complete the irrigation, it gives us the opportunity to plan our schedule for the rest of our agricultural tasks. The implementation of the controller is based on the Arduino Uno R3, where 2 magnetic sensors have been connected in order to count the reel turns and detect the direction, a gsm sim 800l which sends the sms to the user to notify him about the reel operation and an 2X16 LCD screen which displays the parameters of our controller. The power is provided by a 12 v 7Ah zinc battery which is connected to a 10W solar panel through a charging regulator
