Sensor monitoring of planting with output parameterized \"characterized by a sensory system applied equipment configured to planting of seeds with application in precision agriculture.If it differs from the other sensors present on the market by the presence of signal conditioning circuit, system of protection against reverse polarity of input,The new arrangement of emitters \/ receivers, with four transmitters and four fototransistor infrared receivers, and implemented system of change of pulse (PWM).In practice, the sensor is composed of two plates, transmitters (7) and receivers (8) positioned parallel to the driver of the seed (11) as in Figure 8.When the equipment is operating, the transmitter emits the infrared beam which is received by the receiver on the other side of the driver.When the seeds are by the driver, the infrared beam is interrupted, and according to the time of beam interruption, the processor identifies the size of the seed.A seed or how many seeds passed through the conductor.This work shows accuracy of the equipment in the counting of seeds and increases the quality of planting, therefore, for the registration of seeds planted.Disregards the passage of the half seed or seed broken, identified as a fault in the planting, impacting on increasing quality and productivity of seeding.“sensor de monitoramento de plantio com saída parametrizada” caracterizado por um equipamentos sensorial aplicado configurado ao sistema de plantio de sementes com aplicação na agricultura de precisão. se difere dos demais sensores presentes no mercado pela presença de circuito de condicionamento de sinais, sistema de proteção contra inversão de polaridade de entrada, novo arranjo de emissores/receptores, contando com quatro transmissores de infravermelho e quatro receptores fototransistor, além de implementado sistema de variação de pulso (pwm). na prática, o sensor é composto por duas placas, emissores (7) e receptores (8), posicionadas paralelamente no condutor de
