The present invention patent relates to a solution for avoiding errors during the seed-metering process in planters, and comprises the following six steps: autonomous electricity generation to power the monitoring system； monitoring the seed charge in the metering disk (pre-sensor)； monitoring the clogging of the metering disk by seeds (post-sensor)； monitoring obstructions in the seed duct (post-sensor)； processing the monitoring data； transmitting the processed data wirelessly to the central monitoring unit for follow-up and decision-making by the operator. One of the aims of the present invention patent is that of providing a solution for avoiding errors during the seed-metering process in planters, allowing the operator of the machine to be automatically alerted immediately after the error occurs, and also for permanently monitoring the quality of the planting process by means of a wireless data transmission system powered by an autonomous electric unit, dispensing with external batteries and power cables.
