Abstract

This research aims to design and implement a two-leaf automatic door sytem that opens towards the inside by utilizing an arduino microcontroller, HC-SR04 ultrasonic sensor and servo motor. The test results show that the system can work responsively and stably with a good level of detection accuracy and servo movement symmetry. This system has potential to be implemented on a small scale in residential homes, laboratories, or other semi-automatic public spased.

Abstract

The Internet of Things (IoT) technology has brought innovation to various fields, including agriculture and plantations. One of the main challenges in plant cultivation is maintaining consistent irrigation to ensure that plants receive an optimal amount of water. Improper watering can lead to either water deficiency or excess, negatively impacting plant growth and productivity. An IoT-based automatic irrigation system is designed to address this issue by utilizing soil moisture, temperature, and humidity sensors to accurately determine the water needs of plants. The data collected by the sensors is processed by a microcontroller, which then automatically controls the water pump. Additionally, users can monitor and manage irrigation through a smartphone application, allowing for more efficient and flexible watering. With the implementation of this system, it is expected that productivity and efficiency in plant management, both at the household and commercial farming levels, can be significantly improved.
