Modern methods of pesticide application in agriculture, such as hand pumps and drone systems, have significant limitations. Hand pumps are labor-intensive, time-consuming, and expose farmers to harmful chemicals, making them unsuitable for large farms. On the other hand, drones, while technologically advanced, are expensive and ineffective in orchard environments due to structural and operational constraints.

To overcome these challenges, we have developed a low- cost, automated pesticide spraying system specifically designed for small and marginal farmers, particularly those engaged in orchard farming. This system features a sprinkler-based spraying mechanism combined with an automatic height adjustment function, ensuring efficient and uniform coverage of plants at varying heights. Additionally, the integration of soil moisture sensors enables the system to assess soil conditions and estimate the required nutrients, allowing for precise and timely application.

This innovative solution offers the benefits of automation, mobility, and precision. It reduces labor requirements, minimizes farmers' exposure to harmful chemicals, and lowers overall operational costs.
