Development of a Prototype Water Storage Tank Pump for Watering Plant using Internet of Things (IoT) with Solar Energy

The lack of water causes the growth of plants to become stunted. Despite that, system of harvesting water supply for watering plant uses conventional methods that require manpower to control and monitor the process of pumping water. As a result, the automatic Harvesting Water in Storage Tank system can fix the problem. To address the problem of difficulty ensuring adequate water supply for watering plant, IoT and solar energy were developed. The ESP32 built with a Wi-Fi module utilized as a controller system to communicate with the system. The scope of the study was decided before the design was created to ensure that the prototypes produced could meet the objectives set. The goal of this project is to ensure that this water harvesting system can be controlled using wireless technology. The Blynk app is used on a smartphone to control the pump for harvesting water and monitor level of water in the storage tank. Users merely need to open the system in their smartphone to monitor the percentage of water capacity detected by the ultrasonic sensor. These conditions are indicated with three LED for each condition which red (low), yellow (medium) and green (full). The project also uses solar energy, which will save the farmers money and eliminate the use of petrol to produce power for pumping water supply. Therefore, it can be concluded that the study successfully developed a system that addresses the problem of making agricultural work easier.
