Spraying Agricultural Crops Based on Internet of Things (IoT)

Indonesia's Agriculture is a strategic sector in increasing economic growth. One of the efforts to increase agricultural production in Indonesia is through technology. Watering is an essential component in improving the quality of farming products. Developing farming models can improve the efficiency and effectiveness of watering in farmland management. The monitoring and watering system using IOT has many benefits, including time efficiency, work effectiveness, remote operation, simplicity, and better watering accuracy. In this study, Smart Farming System was used in watering arrangements in the chili plantation area. Data on the sensor is used to analyze the effectiveness of water spraying against soil moisture value. The Smart Farming Device was placed in a coastal area with a hot climate in the chili garden. The experiment was conducted 9 hours from 08.00 – 17.00 WIB (West Indonesian Time). The Device works in a modular manner controlled remotely by the internet network, which works by energy converted from the sunlight. The use of types of sensors and the sensors placed on the farmland will determine the accuracy of the information received by farmers. We found that the spraying water method does not raise the soil moisture from the sensors parameter. We also found that the temperature parameter is not correlated with the sunlight intensity. So we need to add a wind speed sensor to determine the effect of wind blow on the environmental parameters. We concluded that the watering method through soil surface seems more promising in increasing the soil moisture value rather than the water spraying system via air.
