IOT based Smart Agriculture-plant watering system with ESP32 and blynk platform

  • Unique Paper ID: 176729
  • PageNo: 7651-7653
  • Abstract:
  • This article presents a real-time agricultural monitoring system based on the NodeMCU microcontroller coupled with IoT-based sensing technology. The system tracks key environmental parameters such as soil moisture, temperature, humidity, and light intensity using DHT11, LDR, and soil moisture sensors. Sensor data is processed and communicated through Wi-Fi to a cloud platform (ThingSpeak) for remote monitoring and visualization. Seamless connectivity is enabled by the NodeMCU ESP8266, allowing real-time updates and alerts. Data analytics on the cloud platform provides insights into precision farming and irrigation planning. The system prevents wastage of water and increases crop yield through timely interventions. Power efficiency and modularity enable the solution to be scalable for large-scale farms. Low-cost hardware and open-source platform implementation ensure cost-effectiveness for small-scale farmers. Performance testing ensures accurate sensor readings and efficient cloud transmission of data. The proposed system demonstrates a viable solution for smart agriculture.
