Automatic Weed Detection & Sprayer Robot

The traditional method of weed removal in agricultural fields involves spraying herbicides across the entire area, which leads to contamination of crops and reduced yield, as some productive plants may die alongside the grass. Thus, a clever weed control technique is required. Crop rows are photographed at regular intervals for this investigation using an image processing method. Once weeds are identified in the photos, herbicide is sprayed just and precisely on the undesirable plants. The container in which the herbicide is kept has water pump motors attached to spray nozzles. When weeds are found, the Raspberry Pi sends a signal to the motor driver IC controlling the water pump motors to spray the chemical directly onto the weeds. This innovative system minimizes herbicide usage, reduces environmental impact, and enhances crop productivity through precision farming.
