Soil moisture is a critical factor influencing crop productivity, soil quality, and erosion risk. Changes in rainfall intensity directly affect soil moisture levels, which in turn impact water requirements in agricultural fields. Therefore, this study developed a system for “Monitoring the Effect of Rainfall on Soil Moisture Based on the Internet of Things (IoT) Integrated with Blynk Application.” The system was designed utilizing a rain gauge sensor, capacitive soil moisture sensor, DHT22 sensor, battery management system, monocrystalline solar panel, and NodeMCU ESP8266 microcontroller, all integrated into the Blynk platform.
The results of this study demonstrate that the monitoring system performed effectively, successfully transmitting real-time sensor data to Blynk. The recorded average rainfall intensity was 27.50 mm/h, soil moisture was 62.73%, temperature was 28.26?C, and air humidity was 85.56%. Based on these findings, it can be concluded that higher rainfall significantly increases soil moisture and air humidity, while the ambient temperature tends to decrease. Conversely, lower rainfall results in reduced soil moisture and air humidity, accompanied by an increase in temperature.
