Automatic Petition Spraying System That Refers to The Parameters of Wind Speed and Time

Abstract

This research aims to design and implement an automatic pesticide spraying system based on wind speed and time using the NodeMCU ESP8266 microcontroller. The system is built to operate only when environmental parameters meet ideal conditions, specifically when the wind speed is between 4–6 km/h and the time is within the operational window of 06:00–08:00 WIB. The system integrates several components, including an anemometer, wind direction sensor, voltage sensor, LCD I2C, relay module, and a DC water pump. Additionally, a push button is used as a manual override feature to cancel spraying. Data is displayed via LCD and sent in real-time to a web server for remote monitoring. The testing process, conducted on a red onion farming field, showed that the system successfully executed spraying only under the defined safe conditions. The push button feature worked reliably as a manual override, and the system responded accurately to changes in wind speed and time. This innovation offers a more efficient and safer alternative for pesticide application, minimizing human exposure to chemicals and reducing pesticide waste. The system is suitable for further development in precision agriculture, with potential enhancements such as GSM integration, solar power, and mobile app connectivity.
