Sistem Monitoring dan Kontrol Tanaman Tin Berbasis IoT

Abstract

Tin plants have various health benefits and high economic value, but these plants need
attention in order to develop properly, so an IoT-based fig plant monitoring and control
system is created. The system can find out the temperature, soil moisture, soil pH, and fruit
color through sensors installed and forwarded to the owner's smartphone for monitoring the
plants through the Blynk application, and can water automatically when the soil starts to dry
and notify when the fruit is ripe. The system is also equipped with backup energy from a
6watt solar cell which from the test results is able to run the system with a load of +/- 17
hours. Solar cells are used if there is a disturbance in the main energy. The components
needed in building this system are a microcontroller, sensors, relays, water pumps, solar
cells, and batteries. The test results of the DS18B20 temperature sensor have an accuracy of
98.99%, the humidity sensor has an accuracy of 86.94% and the soil pH sensor has an
accuracy of 98.22%. With this system, information on the condition of tin plants can be
found through the Blynk application. The hope is that this tool can help plant owners to
monitor their plants and can optimize plant growth with good care.
