IoT-Based Real-Time Soil Moisture and Temperature Monitoring System
摘要
An IoT-based Real-Time Soil Moisture and Temperature Monitoring System is incorporated with ESP32, Soil moisture sensor, Temperature Sensor (DS18B20), LCD and Blynk Cloud. The primary goal is to deliver timely soil condition updates to farmers and gardeners so that, they can make better choices and preserve the amount of land that they have. These devices wirelessly send the data to the Blynk cloud platform, where a user-friendly interface and makes it available further. The Blynk framework is connected to the ESP32 and used as a remote control. The on and off switches are created in the Blynk framework and can be accessed using a smartphone, laptop, tablet, or desktop. The detected data is exhibited in hybrid mode, wherever the low soil moisture value is detected, the motor turns on and vice versa the high moisture value is detected the motor automatically turns off. According to the moisture level sensed by the soil moisture sensor, the on/off signal is sent via the Blynk platform to ESP32 which activates the relay. The relay is connected to the motor and it starts/stops the water supply according to the on/off signaling.
