Agrilink: Design and Evaluation of an IoT-Based Smart Agriculture System for Plant Watering and Humidification

The Smart Water Management for PlantPal: IoT Plant Watering and Monitoring System is an innovative automated solution that helps to maintain an optimal growing environment through real-time monitoring. The work implements IoT technology which integrates ESP32 and ESP8266 microcontrollers with multiple sensors including ultrasonic sensor, soil moisture sensor and DHT22 temperature/humidity sensors. These sensors continuously retrieve important data to assess plant needs. The work consists of two major components, which is the smart water control device assist in control water usage and the mist maker contributes to create an optimum humidity for the plant. Local LCD display will be used to display critical data while web dashboards ensure reliability and user convenience. The testing phase demonstrated the effectiveness of the work, reducing water waste while promoting healthier plant growth. This work offers practical applications particularly for home gardening, small-scale agriculture and urban farming where automation of plant care and efficient water usage are needed.
