Applying Internet of Things Technology for Aeroponic Plant Cultivation via an Android Application

This research is an application of the capabilities of Internet of Things technology and sensor technology to solve the problem of caring for plants while the caretaker is not at home or has no time to take care of them. The researcher has designed a set of aeroponic plant growing equipment. It is controlled by using a NodeMCU ESP8266 microcontroller to operate the water pump to automatically spray water to the roots of plants. Order LED bulbs for growing plants to automatically light plants and receive various values that should be known for caring for plants from the sensor. In this research, we tested the efficiency of plant growth using aeroponic growing kits compared to growing plants using soil. The average stem size and height of the plants used in the experiment were considered compared to those grown in general on soil. The sample plant used in this experiment was spring onion, by growing young shallots by soaking them in water to grow roots for 7 days, then putting the grown roots into a planting kit. 4 sets of aeroponics and regular planting in soil for 25 days. Then, the speed of the sensor displays and the speed of remote operation of the bulbs were measured. The results found that the average height and width of onion plants grown using aeroponic growing kits were 34.4 cm and 0.4 cm, respectively. Meanwhile, the average height and width of onions grown using conventional soil were 35.2 centimeters and 0.4 centimeters, respectively. The speed of displaying various values through the sensor is 2 seconds per time. From 10 experiments, it was found that the speed of operating the light bulb is the fastest at 2.4 seconds and the slowest at 6.8 seconds from the above. Then the above can be considered Aeroponic growing kits were similar in performance to growing plants using soil in the experimental situation.
