This paper presents the development and evaluation of an Internet of Things (IoT)-based control system for small-scale greenhouse environments. The core of the system is the Arduino Nano 33 IoT (SAMD21 Cortex-M0, 32-bit), which integrates multiple environmental sensors to monitor temperature, air humidity, soil moisture, and light intensity. Based on user-defined parameters, the system automates plant care actions: activating an LED lighting matrix, powering a ventilation fan, and triggering a water pump for irrigation. System monitoring and control can be performed locally through an LCD interface or remotely via a cloud-based dashboard. Beyond automation, the study investigates the influence of various types of music - such as classical, techno, and meditation - on the germination and growth of lettuce and radish plants. Experimental results indicate that classical and meditation music enhanced plant development, while techno music had a negative effect, despite otherwise optimal environmental conditions. The findings demonstrate the dual potential of IoT systems for smart agriculture: enabling precision environmental control and exploring novel stimuli, such as sound, to support plant growth.
