Abstract
Automation the process of monitoring the garden can transform garden irrigation process from being manual and static to smart and dynamic one. This leads to higher comfortability, water using efficiency and less human supervision effort. This paper proposes a cloud based Internet of Things (IoT) smart garden monitoring and irrigation system using Arduino Uno. The watering requirement for a plant can be adjusted by monitoring the soil moisture. Measuring the soil moisture of the plant gives information if the plant is ideally watered, over watered or under watered. The proposed system monitors and maintains two quantities of the garden, the garden soil moisture content and light intensity. This is done using soil moisture sensors and light intensity sensor. The monitored data is sent continuously to ThinkSpeak IoT cloud. In the cloud the data gathered from the system is analyzed and when a target threshold of soil moister is reached, an action is sent accordingly from the cloud to the garden automatic watering system to irrigate the garden. Arduino Uno microcontroller is used to implement the system control unit. IoT is used to keep the garden owner updated about the status of the sprinklers. Information from the sensors is regularly updated on a ThinSpeack IoT cloud and the user can check the water sprinklers status at any time. In addition, the sensor readings are transmitted to a ThingSpeak channel to generate graphs for analysis.
