Smart Farming System on Red Onion Plants Based on the Internet of Things

Abstract

How to plan tis a problem that until now still cannot be resolved. Planting crops now is very influential for farmers in today's life, because they have less technique and land to plant. One way to grow plantswel is to measure the quality of Ph and nutrients in hydroponic system. To monitor the hydroponic system manually is not very effective, so in this study a hydroponic monitoring system wa designed, wich can provide real time information, using a Ph meter sensor to measure the wet acid level of a solution, a TDS meter sensor to measure the ttal weight of all solids dissolved in a volume of water, a DHT22 sensor to measure the surrounding air and the signal out on the data pin, a sensor pin (ultra sonic HC04) to measure the distance of an object, and using ESP32 as a microcontroller. The final result of the tool made is that the tool will detect if a nutrient is present. The sensor readings in real time are then sent via the wifi module into the internet of things OVoRD (Online Value Of Real Time Data) platform and displayed web form. This system has the potential to be used as a hydroponic monitoing system
