Vertical Assembled Sprayer for Supplying Water and Liquid Fertilizer

Article Preview

Abstract:

This paper proposes a vertical assembled sprayer for supplying water and liquid fertilizer. This proposed sprayer consists of both iron structure and hardware modules, including a microcon-troller, LCD, keypad, batteries, nozzles, and diaphragm pumps. The height of this proposed sprayer ranges from 1.5 to 4.5 meters so as to be adjusted by a user. The water quantity and the nozzle numbers can be specified by a user’s demand. Moreover, either manual or automatic operations can also be selected by a user. The experimental results have been shown that the average spraying times for using 1 - 4 nozzles are equal to 95.2 sec, 48.41 sec, 32.3 sec, and 24.5 sec, respectively. Moreover, the average spraying times from the experiments are close to the calculated spraying time of microcontroller where the errors are less than 2%.
