Smart Lawn with Water Sprinkler for Garden Using Arduino UNO

Abstract

This paper presents a system of smart lawn and garden water sprinkler using Arduino UNO, whose water tank can be monitored through smartphone. The main purpose of this system is to minimize the issue of water loss and water delivery system by using Internet of Things (IoT) as a platform to monitor the water tank level/status within range of 20 meters from the WIFI module. In this system, interface YFS201 Hall Effect Water Flow Sensor is used to measure the flow rate and volume of water, while ultrasonic sensor is used to detect water level inside the tank. Two systems (integrated) had been tested. Firstly is the proposed system, where the flow rate and volume of water are displayed on the LCD and the reading of the water tank is displayed on smartphone. The second system is watering clock system, which uses Real Time Clock (RTC) for timer setting purpose. The watering clock system shows the timer of watering session on LCD to ensure the user know their lawn and garden have been watered. The proposed system using the Arduino UNO, IoT Platform and Wi-Fi modules is able to immediately notify consumer to control water losses.
