| A capacitive sensor method for measuring billet spacing uniformity with sugarcane (Saccharum officinarm L.) billet planter is investigated in this paper. Therefore, an electronic device based on capacitive sensor was designed and developed to predict the planting spacing of sugarcane billets. It consisted of four components: a rectangular parallel plate capacitor, electronic circuitry, microcontroller, and display unit. Accordingly, a prototype of the precision metering device for sugarcane billets was developed. After calibrating the monitoring system, the results were verified with calibrated curve by means of linear regression and paired T-test. The performance of the device, including quality of feed index (QFI), multiple index and miss index was... |

| The essential functions of a planter are to open the planting furrow, meter the seeds, deposit them in the furrow, cover them and compact the soil around them. The planter precision is affected, in some way, by each of those functions. Function analysis is a tool used in the conceptual phase of product design which allows an abstract formulation for the function of the technical system, thus making it very useful in product design and in the analysis of existing products. Therefore, the technique of function analysis makes it possible to identify, in the various concepts of planters sold in the Brazilian market, which function is not well implemented when considering precision planting of small grains, being this the main objective of this study.
