Smart Agriculture Monitoring System Using IoT

Abstract - The growing need for food security during climate change and diminishing resources requires a revolution in conventional agriculture practices. This paper proposes an all-encompassing Internet of Things (IoT)-based Smart Agriculture Monitoring System that can automate environmental monitoring and irrigation control. The system uses the ESP32 microcontroller and combines various sensors to sense temperature, humidity, soil moisture, soil pH, and water level. The collected data is transmitted to a cloud-based Blynk mobile application via GSM, enabling remote decision-making by farmers. The system also incorporates an automatic water pump operated through sensor limits, which greatly decreases labor, increases the efficiency of water use, and encourages sustainable agriculture. Field testing reaffirmed the effectiveness of the system for real-time use and remote data access.
