Plant Signal Extraction and Classification with Built-in Automatic Irrigation System

Irrigation has been practiced in India and other Asian countries from early times as they are primarily agriculture-based nations. Along with the requirement of external application of water, plant health also depends on factors like temperature, humidity, nutrition etc. In this paper, an automated plant Irrigation system that monitors soil moisture and controls the water suction pump is proposed. The system also has a plant health monitoring system that logs the temperature and humidity values from the DHT sensor and methane content in the environment from the MO sensor via an Arduino microcontroller. A real time clock (RTC) is used to maintain continuous time during the data log even when there is power disruption. The data is analyzed along with the plant's electrical signals that are amplified via an instrumentation amplifier, which can show how plants change their own growth in response to changes in their environment.
