Development and Working Test of Microcontroller-based Automatic Seedling Tools for Hydroponic Systems

Abstract

The purpose of this study is to design a tool that is able to monitor moisture and light automatically and knowing the performance of lettuce seeding tools that are able to monitor moisture and light automatically, this research is descriptive research using the type of Research and Development (R &; D) research with the Waterfall method.  The variables controlled are light and moisture using soil moisture sensors and grow light. The automatic seedling tool modification process consists of 3 stages including making mechanical components, electronic comments, and functional checking and product testing. The data obtained from the sensor readings will be displayed through the LCD screen on the control box. The results showed that the seedling tool can monitor moisture when the moisture is below 60%, the pump will be on and when the moisture is above 60%, the pump will be off, and the light produced with grow light will turn on at 06.00 to 18.00 pm every day. Researchers recommend adding moisture to every shelf, growing lights or LED sensor lights, and fans for further research based on their findings. As a consideration and reference resource addressing the current science on the manufacture and performance test of seedling tools that are able to monitor moisture and light automatically. incorporating the most recent ideas and information on creating and evaluating seedling equipment with automatic light and moisture monitoring. It is anticipated that this researcher will serve as a seeding industry reference.
