iPlant: Implementation of An Automatic Plant Watering System Using NodeMcu ESP8266 and Blynk

This paper presents the design and implementation of an automatic crop irrigation system based on a NodeMcu ESP8266 microcontroller integrated with the Blynk platform. The system is designed to water plants efficiently and maintain plant health by providing a controlled and consistent amount of water. The NodeMcu ESP8266 serves as the main controller, and the Blynk platform provides an easy-to-use remote monitoring and control interface. The system features sensors for soil moisture level monitoring and a flexible watering schedule based on the monitored soil moisture conditions at all times. In addition, we detected the soil moisture to determine whether the visible plants needed water or not. Our test results show that the system is highly effective and efficient. This paper highlights the potential use of NodeMcu ESP8266-based systems integrated with Blynk for automated crop irrigation and successfully making automation with 3 activity which turn on pump based on the sensor, turn on based on command button and sending data to Blynk and has increased. The soil water content ranged from 4% to 80% throughout the experiment demonstrating good humidity level.
