This IoT Smart Agriculture System uses the RS485 Industrial Water Sensor Module 7 IN 1 to monitor soil conditions in real-time. It measures pH, EC (Electrical Conductivity), Soil Nitrogen (N), Phosphorus (P), Potassium (K), Temperature, and Humidity. The OLED 0.96-inch display provides instant readings, while RS485 communication ensures stable data transmission. Integrated with Blynk IoT, the system enables remote monitoring, helping farmers optimize irrigation, fertilization, and crop health efficiently.
