SMART PESTICIDE SPREYER

Wastage of chemical inputs and environmental degradation have been a serious issues with conventional methods of pesticide application in agricultural and horticultural engenderment, resulting in fruit poisoning. A tractor-operated low-cost, ultrasonic sensor predicated selective pesticide sprayer was developed and tested for efficient spraying on the plant canopy and to abstain from spraying in canopy absentia. Sensing technology was interfaced with programmed Atmega328P for automatic spray control through pump, solenoid valves and nozzles. The sensing signals instigated the microcontroller system for desired spraying. The spreyer is designed to adjust spreying direction by determining crop height by the sensors. The technology was provisioned for boom height and nozzle angle adjustment as per canopy geometry. The ultrasonic sensor sprayer was designed for low cost and precise pesticide spraying especially for marginal farmers, thereby reducing both costs and environmental pollution by plant protection products.
