The integration of Internet of Things (IoT) technologies into plant care systems has gained significant traction due to its potential to automate and optimize maintenance processes. This study presents an IoT-based automated plant watering system comprising key components such as a NodeMCU (ESP8266) microcontroller, various environmental sensors, and a relay module. Central to the system is a soil moisture sensor, calibrated via the Blynk application, which facilitates real-time monitoring and remote control from any location. Users can actively manage irrigation by controlling the water pump through the app, ensuring efficient and timely watering based on actual soil conditions. The system has been designed for quick setup, requiring only a few hours and has undergone comprehensive testing to validate its reliability and performance. Its adaptability makes it suitable for both domestic and agricultural environments, offering an effective solution for conserving water and enhancing plant protection across a range of cultivation scenarios. https://www.agriculturejournal.org/volume13number1/iot-enabled-plant-protection-employing-design-thinking-for-effortless-growth/ Agriculture; Blynk; Components; Calibration; Irrigation
