Thus, this project aims to improve the existing sprinklers by including wind compensation. To reduce the effect of wind on the irrigation pattern, the sprinkler velocity and radius of throw need to be adapted to the wind's velocity and direction. Our control valve box contains seven major components. Wind and rain sensors that will collect the weather conditions, an LCD where irrigation time will be displayed, additionally to a microcontroller communicating with a second MC at the sprinkler head box via Bluetooth and controlling an electrically actuated ball valve and solenoids connected to inline pressure reducers. These three latter components play an important role in supplying proper water conditions for the sprinkler by adjusting the pressure and water flow. The position of our sprinkler's nozzle will be detected with a magnetometer and compared to wind direction. The servo motor will rotate the sprinkler and this latter will start irrigating in a 180° pattern for couple of minutes before rechecking again all the conditions. When the sprinkler nozzle is facing the wind the velocity of throw will be increased, and after it is rotated and is in the same direction as wind, the velocity of throw will be reduced, because wind is already assisting the water droplet reach its radius. If the wind velocity is larger than the threshold value, or if it is raining, the system will not start although the switch is turned on. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication 'Bronze Leaf Prize' for an outstanding online video presentation in the category of 'Audience Choice' on January 26th, 2021.}, language = {en} }
