Resumen

Fumigation is one of the most important activities in agriculture. The manual spray bag is the most used spraying tool, with prices above 100 dollars. The constant use of manual spray bags presents health problems in the lumbar areas and the joints of the hands. This research aims to develop and implement a battery-powered fumigation module for manual pumps to reduce physical problems for farmers in the Valle del Tambo in Arequipa, Peru. The module is implemented on the one hand with a leveling of variables with the water level census, and on the other one with the process of the system by power stage. The module is implemented with an Attiny85 microcontroller, 0.48Mpa electric pump, ultrasonic sensor, and power Mosfet. A 12v 7Ah battery powers the system, and the motor is controlled through PWM signals. The farmers approved the module of the Valle del Tambo area and verified the implementation operation, contributing to the approach to technological innovation in the zone. As a result, the module implementation was obtained in 3 manual spray bags of 10, 16, and 20 liters of capacity with an efficiency of 8 hours/hectare, adequate use of the battery, and an ideal temperature for the implemented circuits.
