The surge in popularity and expansion of the Internet of Things (IoT) has brought about revolutionary advancements in agriculture. In this work, a system is proposed that optimizes irrigation and fertilization practices, leading to healthier crops, increased yields, and efficient resource utilization. The present work focusses on the design of a system to monitor soil moisture and nutrient levels for optimal plant growth. For soil moisture detection, we employed a soil moisture sensor with ESP8266, which senses moisture levels in the soil. If moisture levels are low, the system triggers watering to maintain suitable conditions for plant growth. Additionally, for nutrient detection, we utilized a color sensor with ESP32 to detect Nitrogen (N), Phosphorus (P), and potassium (K) values in the soil, aiding in the assessment of soil fertility and nutrient balance. This integrated approach aims to support healthy plant growth by ensuring proper hydration and nutrient availability in the soil.
