Abstract

This project aims to develop an Internet of Things (IoT) based plant monitoring and irrigation system powered by solar energy. The system will enable the efficient management of plants by continuously monitoring their environmental conditions such as soil moisture, temperature and humidity and transmit the collected data to the Blynk platform. The Blynk application can then display this data in the form of interactive widget, providing users with insights into their plants' health and growth. By employing IoT technology, the system will provide real-time data to users, allowing them to remotely monitor and control the irrigation process. The integration of solar energy will ensure a sustainable and environmentally friendly power source for the system, reducing dependence on conventional electricity. Overall, this project offers an innovative solution for plant care, enhancing productivity and conservation through the implementation of IoT and solar energy technologies. The performance of this system can be measured by conducting experiments. First, there is the solar charging test. Next, an assessment of the accuracy of temperature and humidity sensors was performed, achieving a temperature accuracy of 98% and a humidity sensor accuracy of 95%. Additionally, the soil moisture sensor for the irrigation system was tested, resulting in a measurement accuracy error of only about 2% to 3% for the water level sensor. A comparison of plant growth was also conducted, revealing that the plants exhibited slightly better growth, approximately 7% to 10%, compared to traditional farming.
