The increasing demand for sustainable agriculture practices has led to the development of innovative technologies to improve crop yield and resource efficiency. One such advancement is the implementation of smart greenhouse monitoring systems. This paper proposes a smart greenhouse monitoring system utilizing the Blynk application, a user-friendly platform for IoT projects. The system integrates various sensors to monitor crucial environmental parameters within the greenhouse, including temperature, humidity, soil moisture, and light intensity. These sensors provide real-time data, which are wirelessly transmitted to the Blynk application running on a smartphone or tablet. Through the Blynk interface, users can remotely monitor the greenhouse conditions and receive notifications/alerts regarding any deviations from optimal parameters. Moreover, the system incorporates actuators for automated control of environmental conditions, such as adjusting ventilation, irrigation, and shading systems. These actuators can be remotely controlled via the Blynk application, allowing users to optimize growing conditions and respond promptly to changing environmental factors. The proposed smart greenhouse monitoring system offers several benefits, including improved crop yield, resource efficiency, and convenience for greenhouse operators. By leveraging the Blynk application, the system provides a user-friendly interface for monitoring and controlling greenhouse operations, thereby empowering users to make informed decisions and maximize productivity. The integration of Blynk IoT application with smart greenhouse monitoring is innovative and promises enhanced efficiency. The inclusion of actuators for automated control adds a layer of convenience and adaptability to the system.
